Potentiometer-Type Displacement Transducers

Potentiometer-Type Displacement Transducers

PTDT Displacement Transducers are designed to measure displacement by converting expansion / contraction of a sensing wire to electric signal by potentiometer with bridge circuit. Those models are available with rated capacity 250 mm to 4000 mm, all providing a high rated output of 5 mV/V. In addition, measuring force of the wire is constant, thereby making these transducers easy to use.

The PTDT Displacement Transducers provides a voltage signal linearly proportional to the extension of a retractable stainless steel cable. Used for indicating the displacement of the test structure, member or part to which the cable is attached, installation is quick and easy. Simply attach the base of the sensor to a reference surface, the cable to the component being displaced, and the electrical leads to any instrument accepting strain-gage signal inputs. With the certified calibration data and wiring instructions provided with each sensor, you will be making displacement measurements in minutes.
