Explosion-Proof Pressure Transducer / Transmitter with LCD Display

AST46DS

explosion proof pressure transmitter with display

AST46DS explosion-proof pressure transducers feature the latest advances in transducer technology. Capable of using a power supply as low as an 8VDC and low current consumption, the AST46DS pressure transducer can operate in remote areas with minimal power. The re-zeroing function, allows for field calibration in a safe environment to further enhance well site or system readings. Pressures are available up to 20,000 PSI; AST46DS pressure transducers and transmitters are designed for all common oil and gas pressures from shallow to deep wells.
