PREMASREG 7111-U/W

Item No. 1302-7111-4011-200
EAN 4 251325 612836

The electronic PREMASREG® 711x pressure sensors and switches are equipped with eight switchable measuring ranges, one switching output and 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 button for manual zero point calibration (automatic zero point calibration optional) and one offset potentiometer for setting the switching point and one for final value correction. Fine adjustment by the user is possible. The delivery includes the connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).
