Dual pressure sensor as pressure transmitter and differential pressure transmitter PREMASGARD® 722x
Patented quality product (patent no. DE 10 2015 015 941 B4)
Calibratable PREMASGARD® 722x dual pressure transmitter (series) with 2x 8 switchable measuring ranges, 2 automated output signals (32 devices in one), housing with pressure connection nozzle made of impact resistant plastic, optionally with/without display, with cable gland or M12 plug-in 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). We have patented this unique technology.
The device is used in cleanroom, medical and filter engineering, ventilation and air conditioning ducts, spray booths and large-scale catering facilities, in filter monitoring and level measuring or frequency converter triggering. Media measured with this pressure measuring transducer are clean air (non-precipitating) or other gaseous, non-aggressive, non-combustible media.
Both pressure sensors have a piezoresistive measuring element, are temperature-compensated and guarantee a high level of reliability and accuracy. The sensor device provides a push-button for manual zero-point matching as well as an offset potentiometer for correcting the final value. The transmitter is factory-calibrated and can be fine-tuned to ambient conditions by an expert. It is supplied with an ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
