PREMASREG 716x - VA
The electronic PREMASREG ®
filter monitoring and liquid level detection based on pressure measurement in clean air. The devices with a housing made from stainless steel V4A,
with cable gland or M12 connector according to DIN EN 61076-2-101 and pressure port by stainless steel quick connect (pipe fitting optional) are
fitted with one switching output, one continuous output and a backlit display for setting the switching point and displaying the ACTUAL values. The
piezoresistive measuring element guarantees a high degree of reliability and accuracy.
This pressure sensor is used 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. The medium measured is air (non-precipitating),
or other gaseous, non-aggressive, non-combustible media. It has a manual zero point pushbutton and an offset potentiometer for final value correction.
Parameter entry is menu-based and is easy to perform using three buttons with the help of the display. The sensor is factory-calibrated; an environ-
mental precision adjustment by an expert is possible.
