Application examples mainSENSOR 01/28/2016 These patented sensors have found applications in automation, machine building and OEM. They are suitable where large measuring ranges at low cost and high volumes are required. The range of different sensors comprises simple board sensors through to a completely encapsulated high-pressure version.

An indirect measurement of the damper displacement is much more cost effective, realized with a magneto-inductive MDS-40-LP-F displacement sensor, which is directly integrated in the damper. The suds container sinks when the washing machine is loaded, which generates a change of displacement on the damper. This absolute measuring principle detects the position of the piston in the damper continuously and with high dynamics. This load measurement enables an optimum and maximum load for the machine to be determined, as well as the appropriate dosage of detergent. During the washing process, the mainSENSOR dynamically controls the imbalance of the drum and detects the rotational speed during the spinning process, without requiring any additional hardware. Device operation and spinning are improved and the service life of the machine is increased. Rotational speed measurement In addition to displacement and distance measurement, mainSENSOR can also be used to measure rotational speed. In order to do this, one or two magnets are mounted on the rotating measurement object. Regardless of the direction of rotation, the sensor measures the speed of the target object. Customer-specific models enable the recognition of the direction of rotation. This effect is useful for measuring the rotational speed of gear wheels in marine diesel engines.

The sensor measures the valve lift of the filling line and requests several switching points in a measuring range of 35mm. The sealed stainless steel housings of the MDS-45-Mxx series are ideal for the food industry. Here the mainSENSOR replaces several inductive switches which would have to be mechanically adjusted in a complex process before. The continuous, analog output signal enables this adjustment in the control system in an easy way. Source: Uhlmann Pac-Systeme GmbH & Co. KG Foreign body detection in medical technology In this application, the MDS sensor recognizes foreign bodies in blister machines during the tablet packaging process. Via the movement of overhead touching rollers, foreign bodies between the blister packaging and covering material can be detected. Exceeding a pre-defined point triggers an alarm. Further application examples include wear measurement in paper mills, stroke measurement in pneumatic cylinders, position measurement on construction vehicles, building monitoring, filling level measurement and valve lift measurement.
