PREMASREG 7111
Quality product for HVAC sector, accuracy ± 1.5 %
The electronic PREMASREG ®
one 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, 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 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. The delivery includes the connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).
