Pressure and differential pressure measuring transducer PREMASGARD® 121x - Modbus
The calibratable, compact pressure measuring transducers of the PREMASGARD® 121x - Modbus series with Modbus connection can be equipped with an optional display and are used for measuring above-atmospheric, below-atmospheric or differential pressures in the air. The piezoresistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy.
The pressure transmitters feature a configurable offset and a button for manual zero adjustment. Applications of these sensor devices are found in cleanroom, medical and filter engineering, in ventilation and air conditioning ducts, in spray booths and large-scale catering facilities, in filter monitoring and level measuring or frequency converter triggering. Media measured with these pressure transducers are air (non-precipitating) or other gaseous, non-aggressive, non-combustible media. The devices are supplied including an ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
