The calibrateable PREMASGARD
®
1210 series compact pressure sensors with Modbus connection are optionally equipped with display and are used for
measuring above-atmospheric, below-atmospheric, or differential pressures of air. The piezo-resistive measuring element is temperature-compensated
and guarantees high reliability and accuracy. The pressure transmitters are provided with a pushbutton for manual zero point calibration and an adjust-
able offset. Applications of these pressure sensors are in cleanroom, medical and filter technology, at ventilation and air conditioning ducts, at spray
booths, in large-scale catering facilities, for filter monitoring and 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. These differential pressure sensors
are supplied including connection set
ASD -06
(2 m connection hose, two pressure connection nipples, screws).
