Low pressure transmitters series MicroBar

Low pressure transmitters series MicroBar

Low pressure transmitters series MicroBar

The Micro-bar range are two-wire loop powered 4 to 20mA transmitters based on a built-in capacitance based differential pressure cell for low range measurement on air and other dry gases.

More details:

Standard pressure connections are push-fit sockets but units are also available with ¼"NPTF threads. The Liquid Crystal Display shows the measured pressure and status of the alarm outputs. Alternatively, when used in conjunction with Orifice plates, Pitots or other DP based flow sensors, units can be configured to provide root extraction of the pressure measurement, to display flow rate. Two switch outputs are programmable as flow or pressure setpoints or, for flow measurement, to provide a totaliser output pulse.
