Quality product for HVAC sector, accuracy ± 3 %
PREMASGARD

1110 series calibratable compact pressure sensors 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. A PREMASGARD
®
1110 series 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).
