AST46DS Pressure Transducer
Brand: American Sensor Technologies IncAST46DS explosion proof pressure transducers features the latest advances in transducer technology.
With a power supply as low as an 8 Vdc 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.
