PREMASGARD® PREMASGARD 2328

Item No. 1301-12C4-0910-200
EAN 4 251325 618319

The maintenance-free microprocessor-controlled PREMASGARD® 232x - Modbus - T3 (series), with Modbus connection, impact-resistant plastic housing, housing cover with quick-locking screws, optionally with/ without display, is used for detecting positive, negative, or differential pressure measurement in clean air.

The piezo-resistive measuring element is temperature-compensated and guarantees high reliability and accuracy. The pressure transmitters are provided with a push-button for manual zero point calibration and an adjustable offset. Applications of these pressure sensors are in cleanroom, medical and filter technology, at ventilation and air conditioning ducts, at spray booths, in largescale catering facilities, for filter monitoring and level measurement, or for triggering frequency converters. Media measured with these pressure transducers are air (non-precipitating), or other gaseous non-aggressive, non-combustible media.

The pressure sensor has a manual zero point pushbutton. Fine adjustment by the user is possible at any time. The delivery includes the connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).
