Absolute pressure transmitters with 4-20mA output for measuring pressure with an absolute type reference.
Absolute pressure transmitters generate a 4mA output signal when the pressure corresponds to a perfect vacuum. An absolute pressure transmitter is used in applications where the pressure of a gas or liquid is isolated from atmospheric pressure changes, for example when testing a sealed pressure vessel for leaks over a long period of time.
