PREMASGARD
The calibratable pressure sensors PREMASGARD
impact-resistant plastic, optionally with ⁄ without display, with cable gland or M12 connector according to DIN EN 61076-2-10, with metal pressure
port nozzles (quick connect optional), are used to measure positive, negative or differential pressures in air.
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 filter monitoring and 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 piezoresistive measuring element
is temperature-compensated and guarantees a high degree of reliability and accuracy. The pressure sensor has a button for manual zero point
calibration (automatic zero point calibration optional/standard for 25 Pa) and an offset potentiometer for final value correction.
The delivery includes the connection set ASD-06 (2 m connection hose, two pressure port nipples, screws).
