Calibrateable pressure sensors PREMASGARD® 1000 are equipped with four switchable measuring ranges 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. These pressure sensors are used 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 triggering of frequency converters. Media measured with this pressure measuring transducer are air, (non-precipitating), or other gaseous non-aggressive, non-combustible media. The pressure sensor PREMASGARD® 1000 has 4 selectable measuring ranges and therefore, minimizes the div ersity of types and stockkeeping, covering a greater range of applications. This differential pressure sensor is supplied including connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).
