The signal conditioner supplies the potentiometric sensors with a highly stable constant voltage. The wiper signal is picked off without load via a high-resistance input stage and transformed into a proportional standardized output signal. The excellent linearity and low temperature drift ensure full utilization of the outstanding benefits of conductive plastic potentiometers, guaranteeing the reliable, interference-free transmission of signals in installations with close sensor proximity even over long distances. The zero point and range can be adjusted independently of each other within wide limits using spindle trimmers. This facility permits standardized output signals to be adjusted even if the maximum path of the sensors is not completely utilized. The electronic circuitry is accommodated in a polyamide housing designed for clipping on a standard DIN EN 50022 mounting rail. The wide operating voltage range permits to be supplied by unstabilized direct voltage sources. High-grade DC/DC transformers are used in the models with electrically isolated supply voltage and signal conditioning . Both for the unipolar and bipolar standard output signals, only one configuration is required. In addition, the sensor offers an additional voltage source of ?15 V (only MUP 150). This can be used, for example, to supply the electronic circuits of AW series potentiometers.
