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.

This miniature force sensor was optimised with respect to its height and is, at only 3.4 mm, the lowest known sensor with strain gage technology. Hardly higher than the diameter of its connection cable, it can also be housed in conditions where space is limited. Along with its minimal geometry, the force sensor is also particularly light. It has a high resonance frequency to follow quickly changing load alternations. Despite its extreme miniaturisation, in its application it remains completely robust and suitable for industry, not only with regard to the highly flexible cable connections or the full welding of sensors for the measurement ranges ≥ 0 … 10 N. The miniature compression force sensors are flat, cylindrical discs with covered bottoms. The central load application button for taking on compression forces is an integrated part of the top, which is the sensor‘s membrane.

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 high precision torque sensor is designed for both static and dynamic measurements on non-rotating applications. It is particularly suitable for torque measurements on, for instance, extremely small electrical actuating drives and micro-mechanical actuator elements, or for measuring reaction torques e.g. on micro-motors. The high accuracy of measurement also makes this sensor ideal for use as a reference in many fields of industrial manufacture as well as laboratory research and development projects. Not containing any rotating parts, it requires no maintenance if properly used. The strain-gage based sensor’s modular design allows precise configuration for the desired application. With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ±10 V that is proportional to the torque. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function.

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.

This high-precision torque sensor is designed for both static and dynamic measurements on non-rotating parts. The 10mm diameter throughhole can be used to feed parts such as cables or Bowden cables through the sensor. The mounting flanges contain threaded holes and through-holes so that the sensor can be fitted at either end. With no rotating parts, this sensor needs no maintenance when used correctly. The modular design of this strain-gage sensor allows precise configuration for the desired application. With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ± 10 V that is proportional to the torque. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function. With the USB option, in addition to the voltage output, the measurement function is available via USB as well.

This high-precision torque sensor can be used to perform both static and dynamic measurements on non-rotating parts. The internal and external square drive design make this sensor especially easy to fit in existing or new screw-fitting applications. Quality assurance and monitoring of screw-fastening tools are just two applications that can take full advantage of sensor features such as USB port, built-in amplifier and side-load absorbing bearings. With no rotating parts, this sensor needs no maintenance when used correctly. Available accessories include mounting brackets and flange adapters, which enable quick, easy and practical integration of the sensor into existing or newly developed setups and test benches.

The new strain gage amplifier with IO-Link interface enables digitalization of the measurement technology right from the sensor. Its compact design and high degree of protection allow the instrumentation amplifier to be used practically anywhere in the field. Strain gage sensors typically have an output voltage of a few millivolts. In industrial environments, e.g. in the vicinity of electric motors or frequency converters, interference can affect the measurement result when transmitting analog signals. This is reliably avoided using the new strain gage amplifier with IO-Link interface. The analog link between the sensor and instrumentation amplifier is kept as short as possible, the standardized IO-Link communication is fully digital and interference-free. The amplifier is powered directly via the IO-Link interface – a standardized 5-wire cable with M12 socket. Strain gage sensors can be connected via a 4-pin M8 connector.

The amplifier module model 9243 is used wherever measurement signals from strain gauges, potentiometric sensors or DC/DC sensors have to be converted into standard signals. Simply by mounting on conventional DIN-mount rails, it is possible to position the amplifier module on location, in the proximity of the sensor. Especially for rough environments a IP65 version is available. The broad auxiliary power range and the choice between AC or DC permits operation on standard power supplies used in switch gear cabinets. A highly precise reference voltage source is built-in for calibration purposes. A calibrating shunt can also be connected via two separate terminals. This permits deliberate detuning of a strain gauge sensor for calibration or merely to check the measuring chain.
