The calibrateable compact pressure sensors of the
PREMASGARD
®
111x ⁄ 112x ⁄ 112x - SD
series are equipped with eight switchable measuring
ranges and with or without optional display (eight devices in one) and are used for measuring above-atmospheric, below-atmospheric, or differential
pressures 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 pressure sensor has eight selectable measuring ranges and therefore, minimizes the
diversity of types and inventory levels 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).
