Introduction
The MPM426WPF 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 cable and the housing are hermetically
sealed, 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 petrochemicals.
