The differential pressure transmitter 629 series can monitor differential pressure of air and compatible liquids and gases with 0.5% accuracy. The design offers dual pressure sensors that convert pressure change to a standard 4-20mA output signal to be transmitted to two wire circuits.
It has minimal moving parts and small internal volume resulting in exceptional reliability and response. Span adjustments and terminal block zero can be accessed easily under the top cover. It also meets the NEMA 4x or IP66 construction requirements.
