There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...

The new intelligent, two-wire transmitters provide precise, reliable measurement of absolute or gauge pressure and transmit a 4 to 20 mA output signal with a superimposed HART digital signal for ...

Designed to combine high accuracy measurement with high overload protection at reduced cost, Keller’s new PD-39X differential pressure transmitter employs two absolute pressure sensors to measure the ...
