The SLX series is derived from the SL series and has been especially for use in applications in the pharmaceutical, medical and food industries. To reduce machine downtimes, CIP and SIP ("cleaning in place", "sterilization in place") cleaning and sterilization processes are state of the art today. For this purpose, the machine interior is cleaned thermally and/or chemically with high temperature, pressure and aggressive media. The devices of the SLX series are perfectly equipped for use in this area and guarantee maximum reliability and service life thanks to their extremely robust design, a completely sealed stainless steel housing and high media and temperature resistance. KeyFeatures ■ Measuring ranges 10...300 mm ■ Linearity up to ±0.10 % of measuring range ■ High protection class IP68/IP69K ■ Operating temperature sensor up to 200 °C ■ High resistance to aggressive media ■ Customized designs

Based on the SL series, the SLT probes are also characterized by an ultra robust construction and a fully stainless steel housing which makes them suitable for harsh environments. The combination of a hardchrome plated shaft with 6 mm in diameter and precision bearings guarantees highest resistance to lateral forces on the push rod. There are three different functional variants available to meet the demands of most measuring tasks: ■ Spring loaded mechanism: The push rod is fully extended by an internal spring. ■ Pneumatic version 1: The push rod extends by applying pressurized air. An internal spring retracts the push rod after releasing the pressure. ■ Pneumatic version 2: The push rod retracts by applying pressurized air. An internal spring extends the push rod after releasing the pressure. Each sensor requires a carrier frequency measuring amplifier to operate, which evaluates and transforms the sensors signal to a standardised analog output signal of 0...10 V or 4...

The SL series offers ultimate reliability and precision in a small size, and is designed for industrial and lab use. The sensors can also be used under water because of their high protection class and the stainless steel housing. ■ Measurement ranges 10...600 mm ■ Housing ø20 mm ■ Linearity up to ±0,10 % of full scale ■ Protection class IP67, optional IP68 ■ Sensor working temperature up to 200 °C ■ External, or cable electronics with cable break detection ■ Customized versions available ■ Predestined for use in harsh industrial enviroments

he greatest challenge in the use of inductive displacement transducers is the optimization of linearity. Usual linearity deviations are around 0.30 % of the measuring range of the sensors. Values that are significantly below this can hardly be realized. With the help of the LVDT digital controller from eddylab, to which either one or two sensors can be connected, the linearity deviation of inductive displacement transducers can be almost completely eliminated. KeyFeatures ■ Improves linearity up to 0.01%. ■ High resolution (16 bit) ■ High dynamic range ■ Digital output CAN, USB interface ■ Analog output ■ High noise immunity

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). To manufacture self-supporting coils, we use self-bonding wire. During winding, the surface of the wire is bonded using hot air. To ensure the coil connections can be soldered, they are then stripped of insulating enamel using a fully automated milling process. PRUFREX is able to make air core coils with wire thicknesses from 0.045 to 1.6 millimetres.

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors detect when a filling level is exceeded or falls below a limit. Water-based liquids like coolants, AdBlue®, fresh water, waste water, bilge water and oil-based liquids like motor oils, hydraulic oils, fuels and brake fluids can be monitored. Since they contain no mechanical moving parts, their function will not be influenced by dirt particles or other influences. No electrical current is sent through the medium via an electrode with BEDIA sensors, an electrolysis of the medium is not possible. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator. This signal is processed by a microcontroller-based evaluation circuit which activates or deactivates an output stage.

Areas of Application and Advantages BEDIA CLS 10 stands for special versions of our well-proven CLS 40 series for heavy duty applications. Currently, the BEDIA CLS 10 series includes a variety of sensors, which are compatible replacement parts for level switches from Cooper Standard and Robert Shaw which are obsolete nowadays – and this in well proven BEDIA quality. This also includes sensors with 2 complementary CMOS outputs. It should be emphasized that the water sensors with two complementary outputs can be operated with a supply voltage of 4.75 V DC – 32 V DC. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that arises when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator, causing it to oscillate (at a frequency of approx. 600 kHz). Then this signal is processed by a microprocessor-based evaluation circuit.

LVDT sensor with free moveable plunger. The non-contact measurement is completely wear-free. LVDT sensors are primarly used for measurement of movement, displacement and position in vehicles and machines.

Sensors can be adapted to suit customer-specific applications. Particularly for a large number of pieces, customized sensors can be produced efficiently, which results in considerable cost reductions. The compact PCB which contains the sensor element and the evaluation electronics is responsible for the signal preparation, signal evaluation and signal output. The type of measurement (distance or rotational speed measurement) and the required frequency response are adaptable. In addition, the interfaces offer numerous connectivity options. There are several outputs such as current, voltage, PWM and further digital outputs. The design of the housing, the material and the protection class can be adapted to the specific requirements. In cases where space is limited, the side shifted measurement offers a space-saving alternative. For harsh environments, the sensor is designed with a fully sealed stainless steel housing that withstands high pressure, dirt, aggressive chemicals (acids)

The sensors of the MDS-40-MK series are a new generation of cost-effective and flexible magneto-inductive sensors for serial or industrial applications. In addition to the pre-configured preferred types, a combination of further options (power supply, output, plug,...) is possible. The appropriate sensor can be combined from numerous configuration options.

The magneto-inductive MDS-35/-45 sensors are specially designed for industrial environments. The sensors are available in M12, M18 and M30 stainless steel housings or with a flat plastic housing. The pressure-resistant, stainless steel housing is ideally suited to harsh, industrial environments (dirt, oil, chemicals) and the food industry.

mainSENSOR is based on an innovative measuring principle, which has been developed by Micro-Epsilon in order to combine the advantages of both inductive and magnetic sensors. Magneto-inductive sensors are frequently used as alternative to inductive sensors and proximity sensors in process automation, the packaging industry and in machine monitoring. Measuring the distance to a magnet which is fixed at the measurement object, the sensor outputs a continuous, linear signal. As different strength magnets are applied, measuring ranges of between 20 mm and 55 mm can be achieved. However, in order to adapt the measuring range, it is only necessary to change the magnet.

Application examples are often found where the standard versions of the sensors and the controller are performing at their limits. One of our special strengths is having the possibility to adapt our sensors to the individual requirements of our customers. The various measuring principles can be modified in different ways. Changes requested include, for example, modified measuring ranges, integrated controller, modified designs, mounting options or integration of different interfaces. Together we will find the best solution for your measurement task.

The sensor elements of the EDS series are protected by a pressure resistant stainless steel housing. As target, an aluminum sleeve is used which is integrated into the piston rod and is passed without making contact and wear-free over the sensor rod.

The MSC controllers are designed to be operated with LVDT and LDR measuring gauges and displacement sensors. Due to the robust and compact aluminum housing, the controllers are ideal for industrial measurement tasks. A large variety of compatible, inductive displacement sensors and gauges combined with an optimized price/performance ratio opens up multiple fields of applications in automation technology and machine building.

The LVP-25-Z20 and LDR-14-Z20 sensors are used for monitoring the clamping position in machine tools. These inductive sensors are integrated in the release device and directly measure the clamping stroke of the drawbar onto which the target ring is glued. Due to their extremely compact design, these sensors are used for different types of tools while providing high-precision and continuous monitoring. No adjustment is necessary when changing the tool.

The specific sensor configuration of the linear displacement sensors in the LDR series is characterized by a short, compact design with small diameter. The compact design and the small sensor diameter facilitate the installation of the measurement systems in locations where space is restricted.

LVDT gauging sensors are equipped with a plunger and fitted with a return spring. The measuring probe can be interchanged with commercially available measurement probes. Measurement probes are primarily used for the measurement and inspection of work-piece geometries (length, width, diameter, thickness, depth, height, etc.).

The compact DTD inductive sensor system consists of a gauge with a plunger guided by a plain bearing and a controller, which are connected to each other with a 3 m long cable. The controller has a diameter of just 18 mm and the 3m-long cable enables flexible installation. The DTD sensor system is based on an established LVDT measuring method. It impresses with outstanding precision and provides high signal stability and resolutions down to the micrometer range. Thanks to its high temperature stability, resistance to shock and vibration, and insensitivity to dirt, the induSENSOR DTD is ideal for industrial measurement tasks. Modern fieldbuses such as Ethernet, PROFINET or EtherCAT are supported via optionally available interface modules.

Micro-Epsilon offers a large range of inductive sensors for displacement and position measurement from conventional LVDT sensors and inductive sensors with integrated controller to customer-specific high-volume versions. The induSENSOR displacement sensors from Micro-Epsilon are used in automated processes, quality assurance, test rigs, hydraulics, pneumatic cylinders and automotive engineering.

Modifying the standard eddyNCDT sensors is sometimes necessary particularly for small and large series. Therefore, we modify the measuring systems according to your specific requirements, e.g., changes to the cable, sensor material and design, and to the controller. In particular, sensors with integrated electronics in a miniature housing or special sensor designs are often requested by systems integrators.
