PREMASREG 711x - VA
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 with a housing made from stainless steel V4A, with cable gland or M12 connector according to DIN EN 61076-2-101 and with
pressure port by stainless steel quick connect (pipe fitting optional) is used to measure positive, negative or differential pressures in clean air, with
limit value switching. The piezoresistive 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 filter monitoring and 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 button for manual zero point calibration (automatic zero point calibration optional) as well as one offset potentiometer for
setting the switching point and one for final value correction. The sensor is factory-calibrated; an environmental precision adjustment by an expert is
possible.
