Explosion-Proof
Pressure Transducer / Transmitter with Display
AST46DS explosion proof pressure transducers features the latest advances in
transducer technology. With a power supply as low as an 8VDC and low current
consumption, the AST46DS 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. Pressure ranges are available up to 20,000 PSI; these
explosion-proof pressure transducers and transmitters are designed for all common oil
and gas pressures from shallow to deep wells.
Explosion Proof: Class I & II Division 1 / 2 Groups A, B, C, D, E, F, G
