PREMASGARD
1000 series calibrateable compact pressure sensors are equipped with eight switchable measuring ranges and with
display (4 devices in one) and are used for measuring above-atmospheric, below- atmospheric, or differential pressures in air. The piezo-
resistive measuring element is temperature and pressure 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 sen-
sors are in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering fa-
cilities, for monitoring filters, for level measurement or for triggering frequency converters. Media measured with these pressure trans-
ducers are air (non - precipitating), or other gaseous non-aggressive, non-combustible media. A PREMASGARD
sensor has 4 selectable measuring ranges and therefore, minimizes the diversity of types and stockkeeping while covering a greater
range of applications. The differential pressure sensor is supplied including connection set ASD-06 (2 m connection hose, two pressure
connection nipples, screws).
