Remote Resistance Transducers

Posted on Posted in Transducers


DIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN  rail cases


Used to convert various inputs into standard DC signals for driving panel meters and for use in control devices.


Selection Guide

M100-RPM Resistance measurement

Typical Applications

The M100-RPN is designed to measure the resistance of 3 wire potentiometers, where the resistance value is proportional to the position of the wiper of the potentiometer. The output value from the M100-RPN is directly proportional to the resistance value at the wiper. A typical application is monitoring remote resistance of potentiometer used in manual valve control.
