Introduction
The MPM426WPC level transmitter is a fully welded,
submersible level measurement device. It uses a
piezoresistive OEM pressure sensor with proven
long-term stability and reliability, and a special digital
compensation circuit that are built into a stainless steel
housing. The integrated structure and standardized
output signal make it easy for the on-site use and
automatic control. The vented Teflon® jacketed cable
and the housing are hermetically sealed, which can be
used in the liquids that are compatible with the sensor
material for a long time. It is mainly applied for the
pressure measurement and control of multiple chemicals.
