Quality product for HVAC sector, accuracy ± 1.5 %
The electronic pressure sensors and switches PREMASREG® 1141 are equipped with eight switchable measuring ranges, one switching output, one continuous output and with 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 level of reliability and accuracy. The pressure sensor is used in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, large-scale catering facilities, for monitoring filters and level measurement or for triggering frequency converters. The medium measured by the pressure measuring transducer is air (non-precipitating) or gaseous, non-aggressive, non-combustible media. The pressure sensor has a manual zero point pushbutton and an offset potentiometer for correction of the final value and the switching point. 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.
