PREMASGARD
The calibrateable compact pressure sensors of the PREMASGARD
ranges, 2 switchable output signals (16 devices in one) and with or without optional display and are used for measuring above-atmospheric, below-
atmospheric, or differential pressures in air. The piezo-resistive measuring element is temperature-compensated and guarantees a high degree of
reliability and accuracy. These pressure transmitters have a pushbutton for manual zero point calibration and an adjustable offset. Applications of
these pressure sensors are in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering
facilities, for monitoring filters, for 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 differential pressure sensor is supplied including connection
set ASD-06 2 m connection hose, two pressure connection nipples, screws).
