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 and Volume flow 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). You can find further device types under
