PREMASGARD 1140 ⁄ PREMASREG
Quality product for HVAC sector, accuracy ± 1.5 % or ± 3 %
The calibrateable compact pressure sensors PREMASGARD
ally with or without 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- ggressive, non-combustible media. A PREMASGARD
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).
Electronic pressure sensors and switches PREMASREG
continuous output, and a display for setting the switchpoint and to display the ACTUAL pressure (eight devices in one plus differential pressure
switch ⁄ differential pressure monitor and continuous pressure sensor in one and the same device). The pressure sensor is used for above-atmos-
pheric, below-atmospheric, or differential pressure measurement in clean air with limit value switching. The piezo-resistive measuring element
guarantees a high degree of reliability and accuracy. 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 PREMASREG
switchpoint correction. Fine adjustment by the user is possible at any time. A connection set ASD-06 (2 m connection hose, two pressure connection
nipples, screws) is included in the scope of supply.
