PREMASGARD
The calibrateable compact pressure sensors of the PREMASGARD
ranges and with or without optional display (eight devices in one) 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 PREMASGARD
212x - SD (3-conductor connection) with switchable output (0 -10 V / 4...20 mA).
