DET Series Displacement Sensors
DET series Displacement Sensor is based on the principle of differential inductance, which converts linear moving mechanical quantity into electric quantity, so as to automatically monitor and control displacement. It has the advantages of high temperature resistance, small size, high accuracy, stable performance, reliable operation and long service life. It can run continuously for one overhaul cycle of steam turbine without maintenance and replacement.

NOTES
1. Sensor wires: primary: brown yellow, sec1: black green, sec2: blue red.
2. Linear range: within two scale lines of the sensor rod (based on “Inlet”).
3. The sensor rod number and shell number must to be consistent, supporting the use.
4. Sensor fault diagnosis: measure PRI coil resistance and SEC coil resistance.
5. Keep sensor shell and signal demodulation unit away from strong magnetic fields
