PREMASGARD 1140 ⁄ PREMASREG
Quality product for HVAC sector, accuracy ± 1.5 % or ± 3 %
The calibratable compact pressure sensors PREMASGARD
with or without optional display (eight devices in one) and are used for measuring above-atmospheric, below-atmospheric, or differential pressures
in air. The piezoresistive 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
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).
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 a single device). The pressure sensor is used for above-atmospheric,
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 1141 has a manual zero point pushbutton and an offset potentiometer for final value and 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.
