　　The signal conditioner supplies

　　the position transducer with a

　　highly stable,constant voltage.

　　The wiper signal is picked off

　　without load via a high-resistance

　　input stage and transformed into

　　a displacement-proportional

　　standardized output signal.

　　The excellent linearity,low tem-

　　perature drift and sensor-proximity

　　of the signal conditioning process

　　ensure full utilization of the out-

　　standing benefits of the position

　　transducers,guaranteeing

　　reliable,interference-free

　　transmission of signals over long

　　distances.

　　In the adjustable models,the

　　zero point and range can be

　　adjusted within wide limits using

　　spindle trimmers.This permits

　　standardized output signals to

　　be adjusted even if the maximum

　　path of the transducer is not

　　completely utilized.

　　The electronic circuitry is inte-

　　grated into a socket to fit the

　　DIN 43650 appliance plug.A

　　wide range of operating voltages

　　can be supplied by an unstabi-

　　lized direct voltage source.

　　Selected SMD components

　　with a wide temperature range

　　guarantee maximum operating

　　reliability even under extreme

　　environmental conditions.

　　The MUW is connected by

　　means of a four-pole terminal

　　strip.It is possible to orient the

　　connecting cable as required by

　　turning the housing insert in 90°

　　steps.
