PREMASGARD 1140 ⁄ PREMASREG
Quality product for HVAC sector, accuracy ± 1.5 % or ± 3 %
The calibrateable compact pressure sensors PREMASGARD
display (4 devices in one).
Electronic pressure sensors and switches PREMASREG® 1141 are equipped with four switchable measuring ranges, one switching out-
put and one continuous output, and a display for setting the switchpoint and to display the ACTUAL pressure (four 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-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 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.
