 MP101 Liquid Level Sensor - Millivolt O/p:

GENERAL

Micron's Model MP100 is a small diameter, high-stability (water/liquid level) pressure transducer. These are made of corrosive resistant titanium (6AL4V) and utilize high reliability bulk type semiconductor strain gages bonded directly to the inside surface of the machined diaphragm.

 Liquid Level Sensors 

 

Model MP101 is a constant current excited transducer recommended for high accuracy applications where the input resistance to the transducer may vary due to temperature induced line resistance changes as occurs in long cable lengths. The MP101 automatically corrects for such changes.

With a diameter of only 0.375 inches, the transducer can easily be installed in holes of a half inch in diameter. Transducers are available with cable lengths up to 1000 feet; greater lengths are possible through splicing.

This product is available with an internal hermetic seal that dramatically improves reliability and accuracy. At the cable exit, titanium armor is provided to improve cable pull strength while retaining a liquid seal. A moisture insulator located near the end of the cable is available and eliminates inter-conductor condensation.
