Force measurement - Import export

The force measuring chain has been developed for applications where the requirements for precision are not the primary focus, but rather where an economical purchase price and simple functionality are the key criteria. The sensor‘s strain gauge technology allows both static and dynamically changing forces to be measured. The large display means that the force acting on the sensor can be read easily. The four integrated threaded holes allow the sensor to be integrated quickly and easily into existing production and assembly equipment. Typical applications include: —Testing the strength of welded joints —Sports medicine —Monitoring the clamping force of hose connections The body of the sensor is a flat, cylindrical disk, into which a domed force application knob is integrated. It is important that the force is applied axially to the center of the sensor.

The newly developed sensor PROFIBUS module model 9221 is predestined for the integration of various analog sensor output signals into complex, net worked and peripheral automation structures. This module finds its fields of application in the industrial automation technology as well as the test rig technology based on its secure and reliable transfer mode, the fast transfer speed and its simple construction. The inputs (e.g. PLC signal gauge) and outputs in addition to the external control allow a zero compensation by trigger via proximity switch or fast alerting on passing of set point values. Industrial type connection and mounting techniques enable the user the adaption and integration in the existing mechanical and electrical environment. The excellent quality of measurement together with the high grade capture of mean values also enable the application in research and development. The use of standardized PROFIBUS protocols makes the connection an easy task for the programmer.

Inside the multi-component force transducer are two webs, each offset by 90°, each with a strain gage full bridge, which convert the radially acting X / Y forces on the guide bush into an electrical signal. Due to the sensor body made from a block with its special structure, the sensor has a very high degree of dimensional accuracy and low crosstalk between the two forces. Due to the special design, the sensor has excellent linearity properties and is designed for a long service life in dynamic applications. The two independent signal connections allow flexible adaptation and further processing. Features: — Measuring ranges: 0 ... 4448 N / 0 ... 2224 N (0 ... 1000 lbs / 0 ... 500 lbs); 0 ... 8896 N / 0 ... 4448 N (0 ... 2000 lbs / 0 ... 1000 lbs) — Further measuring ranges on request — Non-linearity < 0.1 % F.S. — Low cross talk < 0.75 % F.S. — High dimensional accuracy, because sensor is made from one part — Excellent price/performance ratio

LOAD CELL AND TORQUE SENSOR – X/Y/Z - Model 8565 In robotics and automation engineering, the requirements for precise, tactile handling are constantly increasing. The robust 8565 multi-axis sensor with its low crosstalk enables you to monitor and evaluate your process at any time, regardless of the sensor’s orientation. With just one sensor, you can obtain accurate three-dimensional load information. Its six independent outputs let you selectively evaluate the direction of action of the loads (axial force [Fz] / lateral forces [Fx/Fy] / torque [Mz] / bending moment [Mx/My]). Thanks to its compact design and adaptation via the standardized robot flange in accordance with DIN ISO 9049-1, the sensor can be integrated into many applications quickly and easily. When the slightest deviations are detected in your fast-moving and complex production processes, you can intervene immediately to make adjustments. This helps to prevent faulty parts and reduce manufacturing costs.

The SENSORMASTER 9163 covers a wide range of applications in which process values need to be measured, displayed, analyzed and transferred to higher-level control systems. Typical applications include measuring geometric values in production, for instance differential measurements, or testing material properties in the laboratory. The measured values can be transferred via USB, RS232 or analog output. Features: — For force, pressure or torque measurements using strain gauge sensors — For position or angle measurement using potentiometric or DC/DC sensors — For temperature measurement using Pt 100 sensors or thermocouples — Optional multi-channel model — Optional Profibus or serial interface — 0.1 % measurement accuracy plus sensor-specific linearization — Range of mathematical functions (e.g. differential measurement) — OK/NOK feedback on multi color display and via 4 alarm limit outputs — High sampling rate (500/sec.)

The range of functions has been limited deliberately to ensure operation is simple and self-explanatory. With its unique, large and clear digit height of 20 mm, the digital display can be installed easily in process control panels and control cabinets. Thanks to the large choice of measurement signals that can be indicated, the display is ideal for use in a huge range of industry-based applications. As a simple and compact digital display, it can also be used as a multi-channel solution in laboratory or test systems, where several different measurements may need to be taken and displayed simultaneously. Specific characteristics: — Less expensive digital display — For force, pressure or torque measurements using gauge sensors — Two limit alarms optionally available — Extremely easy-to-read display with 20 mm digit height — Display range -1999 to + 9999 — TARE function — Scaling possible using teach-in procedure or by entering sensor data directly

The force to be measured must be introduced axially and perpendicularly to the entire surface of the inner and outer bands of the sensor in the opposite direction. Conversion of the acting force into an electrical output signal is performed by strain gages connected together in a full bridge circuit. To achieve optimal accuracy, the base of the sensor should rest on a smooth level surface, hardened to at least ≥ 58 HRC with sufficient dimensions. The base cover welded to the surface has a stabilizing effect on the sensor element. Lateral forces must be avoided anyway as they distort the measured results. Tension and bending relief for the sensor cable is to be carried out on the machine side. FEATURES: — Measuring ranges from 0 ... 100 N to 0 ... 200 kN — Centric throughout hole — Flat disc design — Made of stainless steel — Completely welded sensor body — Nominal characteristic value standardization possible — burster TEDS optionally available

The force measuring chain is an universal reference measuring chain for the calibration of press-fit force measuring equipment. It finds applications in the quality assurance, commissioning and equipment monitoring fields. A DAkks calibration certificate is included so that the force measuring chain can be traced back. The calibration is traceable through accreditation at the German Accreditation Body. The calibration certificate records the displayed values for mounting positions at 0°, 120° and 240°. During calibration in field, the reference load cell is inserted in line with the flux of the press-fit measuring equipment. The force application is of central significance here for the quality of the measurement. Special force application parts are required, so that the line of action of the force agrees as exactly as possible with the geometrical axis of the load cell that is to be measured (central loading).

This, related to its measuring range, miniaturized load cell enables an universal and reliable operation in industries and laboratories. It is well suited for compression measurements in very restricted structures. The load cell is a compact construction and made of superrefined steel. Therefore it can be used in many fields of industry, like. Examples are: — Press-in force measurements on longitudinal and transversal connections — Compression force measurements on punch and roller applicancy — Spring tension measurements on shock absorbers for cars — Contact pressure determination in push rods — Compression force measurements on compressed-air knee-lever presses Thanks to the rounded top, in shape of a little hat, the force to be measured is led into the sensor centrically and free of lateral force. Specific characteristics: Very small dimensions Drug chain qualified cable Made of stainless steel burster TEDS optionally available

Due to their small dimensions and sturdy construction, these miniature compression load cells made of stainless steel can be used in a wide range of industrial applications and in laboratories. This compression load cell is easy to handle and its installation is uncomplicated. Its small size makes it perfect for use in very restricted structures for both static and dynamic compression force measurements. The miniature compression load cell model 8415 is a flat cylindrical disc, the bottom of which is closed with a cover. The load application button for receiving the compression forces is an integrated part of the sensor. A strain gage full bridge is applied in the gauging member of the measuring element. This produces bridge output voltage directly proportional to the measured force. The small diameter of the sensors results in high rigidity and a short measurement range. The measuring force has to be applied centrically and free from lateral forces.

This force measurement chain was developed for applications where a low cost solution is more important than achieving high levels of accuracy. The sensors strain gauge technology allows the measurement of static and dynamic forces. The load cell is also designed for applications that provide only little space due to its compact design. These properties, together with the sensors dust protection, make the measuring chain suitable for a wide range of applications, such as Industrial manufacture Manufacture of customized machinery Geological investigations Motor vehicle engineering Commercial agriculture Bridge building The body of the sensor is a flat, cylindrical disk, into which a domed force application knob is integrated. It is important that the force is applied axially to the center of the sensor. The domed form, however, minimizes the effect of a force that is not exactly axial.

The precision Pt100 simulator is used wherever measuring instruments or controlling systems have to be tested or calibrated with great precision. The standard version model 4506 simulates 24 set temperature values. Totally different temperature ranges are required in the case of special applications, such as in the food industry, the medical science etc. Model 4506 S is recommended for these applications and can be fitted with 24 temperature values according to customer specifications. A distinctive feature of these simulators is their simple operation. The resistance values required for simulation are directly set in °C. There is no need to use loof-up tables. Today in many cases a certificate is needed more than ever force measurements. This certificate is available under order code 45DKD-.. . Features: 24 set temperature values Calibration per DIN EN 60751 Resistor material: MANGANIN®, TK ≤ 10 ppm/K Pt100, Pt500, Pt1000 Available with DKD Certificate if required

Due to their extremely compact design, these load cells can be used wherever static or dynamic load forces have to be measured in very tight spaces. Model 8416 is perfect for use in micro-technology and just as suitable for measuring tasks in the research and development sector. The ultra-miniature compression load cell model 8416 is a flat, circular disc, the bottom of which is sealed with a cover. The load application button for receiving the compression forces is an integrated part of the sensor. The sensor element inside the body carries a strain gage full bridge which outputs voltage directly proportional to the measurement variable upon application of force. The short nominal measurement distance of the ultra-miniature compression load cells due to their design provides a high degree of rigidity. If needed, the nominal characteristic value can be standardized in the sensor connection cable.

These models are among our most precise and yet mechanically robust miniature load cells. High accuracy, finely graded measuring ranges, small dimensions and the simple introduction of force via opposing threaded pins open up a wide scope of laboratory and production applications. Their sophisticated engineering with integrated support membranes and overload protection reduces additional design expense in many applications, e.g. for external overload protection or guiding the parts introducing force to the cell. The result is that less space is required, less material is used and less weight is involved. Last but not least, there is hardly any friction on components that could falsify the measurement result. The force to be measured is introduced centrally and axially to the cylindrical sensor body in the tension or compression direction by means of the two threaded pins. This requires the sensor to be mounted without any elements touching the end faces of the sensor housing.

The tension & compression load cells from the 8523 series are designed for a wide range of uses. The sensors feature many benefits, including three point-contact mounts for tilt-free installation. Thanks to this feature, excellent measurement results can be achieved even with a sub-optimum mounting surface. The force to be measured is applied to the central threaded hole in the tension or compression direction. For measuring purely compressive loads, using load buttons from our accessories range saves the need for complex sensor-integration mechanisms. Tensile loads in rods or chains can also be detected with ease using the optional pull plate. Inside the sensor is an elastic membrane, on which are applied strain gages connected in a full Wheatstone bridge. FEATURES Measuring ranges from 0 ... 20 N to 0 ... 5 kN Tilt-free installation thanks to point-contact mounts Excellent price/performance ratio Easy mounting burster TEDS optionally available

Thanks to its compact shape and three fixing holes on its underside, the 8526 compression load cell can be used in a variety of applications. With its wide choice of measuring ranges from 0 ... 100 N up to 0 ... 1 MN, it really can cover a wealth of measurement tasks, from the laboratory to use in heavy industry. The integral load button provides an easy and reliable means of applying the force to be measured. Angle errors in the load application with a deviation from the measurement axis of up to 3° have only a minor influence on the measurement signal. For ideal measurement accuracy, the load cell should be mounted on a surface that has been ground and has a hardness of at least 60 HRC. The model 8526 load cell is designed with an internal elastic membrane, to which strain gages are attached. When a compressive load is applied to the load cell, the membrane is elastically deformed and transfers its tension to the strain gages.

The load cell measures the compression forces between the circular contact surfaces of plunger and tool. The pin on its top side and hole on its lower face are simply provided for mechanical fixing and centering the components correctly. To provide as large a range of mechanical compatibility as possible, the pins/holes are available in different diameters. Attachments are available which clamp onto the press sensors to enable easy mounting of displacement sensors according to the circumstances of use. FEATURES: — Measuring ranges from 0 … 100 N up to 0 … 25 kN — Small, compact design — Pin/hole diameter from 8 mm to 16 mm — Different diameter for pin and hole can be combined — Mechanical overload protection for all measurement ranges

The model 8527 high-precision compression load cell is the ideal load cell for reference measurement chains where highly precise measurement results are required. Its very high production quality and extremely low non-linearity of just 0.035 % F.S. make it a dependable choice for comparative measurements and calibration tasks. Designed for a dynamic stress of up to 100 % of the full scale value, the model 8527 load cell is also suitable for situations where a rapid signal change with high amplitude occurs and has to be measured. The model 8527 high-precision compression load cell has a domed load button on top, onto which the compressive load being measured is applied. Inside the load cell is an elastic membrane, on which strain gages generate a resistance change in the measuring bridge and an output signal proportional to the load. For the best possible measurement results, the force should be applied axially and centrically to the load button.

This low cost tension/compression load cell is an especially robust component, which can be easily integrated in a girder assembly between two cables or chains for measuring force. The standard model comes with internal thread, allowing any adapter parts, for instance eye brackets, to be fitted in the axis of symmetry. Alternatively, the optionally available adapters with external thread can be used for quick and easy screw-fitting into a threaded hole made for the purpose. The radial connection cable is extremely flexible and designed for a wide range of motion. In order to achieve the greatest possible stability for such a small sensor, making it suitable not only for the laboratory but also for industrial use, all parts have been welded together including the cable guide bush in the sensor housing. burster TEDS with an electronic sensor datasheet or standardization of the output signal in the sensor connecting cable are offered as options

The Load cell model 8451 has been developed for measuring the forces that occur during press operation. The internal measuring elements have a rugged design, which mean they can cope reliably with the steep force curves that are typical of press applications. They can be fitted or replaced quickly and easily on the press ram without the need for additional components around them. The force sensor is placed between the tool and the press ram and can thus measure the actual compression force directly in the axis of operation. The load cell measures the compression forces between the circular contact surfaces of plunger and tool. The pin on its top side and hole on its lower face are simply provided for mechanical fixing and centering the components correctly. The connecting cables are suitable for drag chains, designed for many movements and stably fastened in the sensor housing.

The SM71 series force sensors were specially developed for measuring clamping forces. The short measuring path of 0.019 - 0.14 mm (depending on the measuring range) and a natural frequency in the kHz range guarantee optimal results even for highly dynamic tasks. Typical applications include the simple determination of screw preloads, where the force sensor is used as a “measuring washer”. The very good reproducibility is less than one percent of the nominal load. The sensor is available in measuring ranges from 20 up to 2000 kN. Hardened washers are already included in the scope of delivery for quick and easy installation. The extremely simple and robust design is made entirely of stainless steel (protection class IP68).
