Dual pressure sensor as pressure transmitter and differential pressure transmitter PREMASGARD 7225 Q LCD

Patented quality product (patent no. DE 10 2015 015 941 B4)
Calibratable dual pressure sensors/dual differential pressure transducers and volume flow transducers PREMASGARD® 722x (series) with 2 x 8 switchable measuring ranges, 2 automatic output signals (32 devices in one), housing with pressure connection spigot made of impact-resistant plastic, optionally with/without display, with cable gland or M12 plug connector in accordance with DIN EN 61076-2-101 for measuring positive, negative or differential air pressures. The pressure transmitters automatically detect the required output type and convert the measured variables into the required standard signal of 0-10 V or 4...20 mA (Automatic Output Switching). We have had this unique technology patented.


They are used in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths and commercial kitchens, for filter monitoring and level measurement or for controlling frequency converters. The measuring media of the pressure transmitters are clean air (non-condensing) or gaseous, non-aggressive, non-flammable media.
Both pressure sensors with piezoresistive measuring element are temperature-compensated and guarantee high reliability and accuracy. The devices have a button for manual zero point adjustment and an offset potentiometer for final value correction. The sensors are calibrated at the factory; fine adjustment by a specialist is possible depending on the environment. The delivery includes the ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
