PREMASREG 716x
The electronic PREMASREG ®
monitoring and liquid level detection based on pressure measurement in clean air. The devices with a housing made from impact-resistant
plastic, with cable gland or M12 connector according to DIN EN 61076-2-101 and with metal pressure port nozzles (quick connect optional) are
fitted with one switching output, one continuous output and one 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 delivery includes the connection set ASD-06 (2 m connection hose, two pressure port nipples, screws).
