industrial pressure transmitter is a standard
and most
popular transmitter applied in air and liquid
pressure measuring. A high
sensitivity silicon pressure chip is employed
in the sensor. The most important
specification for industry application is
long term stability. The PRM300
pressure transmitter is designed for industry
application with perfect long term
stability.
