Microsensor Corp MPM4700 Level Transmitter

Microsensor Corp MPM4700 level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses a highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation, and linearity correction technics for production.

The water-proof cable connects with housing sealed, with vented tube putting in, the transmitter could be used in the water or liquid for a long time. Integrated construction and standard output signal could provide easy operation and good automatic control.

With 2-wire working, compact size, lightweight and easy installation and operation, it is widely used for industrial field instead of normal 2-wire 4mA~20mA DC analog output transmitter.
