PREMASGARD
Patented quality product (patent no. DE 10 2015 015 941 B4)
Calibratable dual pressure sensor PREMASGARD
in one), housing with pressure connection nozzle from impact-resistant plastic, optionally with/without display, with cable gland or M12 connector
acc. to DIN EN 61076-2-101 for measuring overpressure, underpressure or differential pressure of the air. The pressure measuring transducer
automatically detects the required output type and converts the measurands into the required standard signal of 0–10 V or 4...20 mA (Automatic
Output Switching).
It is used in the clean room, medical and filter technology, ventilation and air conditioning ducts, spray booths, large-scale catering facilities, for filter
monitoring and level measurement or for triggering frequency converters. Media measured with this pressure measuring transducer are clean air
(non-precipitating), or other gaseous, non-aggressive, non-combustible media.
Both pressure sensors with piezoresistive measuring element are temperature-compensated and guarantee a high level of reliability and accuracy.
The device has a push-button for manual zero point matching as well as an offset potentiometer for correcting the final value. The sensor is factory-
calibrated; an environmental precision adjustment by an expert is possible. The delivery includes a connection set ASD-06 (2 m connection hose, two
pressure connection nipples, screws).
