Microsensorcorp MPM4730 Intelligent Pressure Transmitter

Microsensorcorp MPM4730 pressure transmitter is a highly accurate and stable intelligent pressure transmitter. It uses digital temperature compensation, non-linearity correction technics, and the most advanced transmitter production technique, the whole product has a compact size, high accuracy, lightweight and wider pressure range, which can be used for flow pressure precise measurement.

The product will instead of the 2-wire working 4mA~20mA DC output analogous signal.
