American Sensor Technologies Inc. (AST) has released the AST46HA, a media-isolated explosion-proof sensor with digital compensation and single-seal approval. Featuring all stainless-steel construction and approved to CSA30 (UL1203/FM3615) Class 1, Division 1 and Zone 1 Group IIB Explosion Proo, Groups C and D, the AST46HA is a solution for extreme temperature applications, including arctic environments and off shore platforms.

While oil filled sensor technologies can experience freezing or boiling at extreme temperatures, the AST46HA pressure sensor utilizes a one-piece stainless steel, non-oil filled sensor design offering continuous operation at temperatures. The company says it is ideal if linearity and repeatability are critical for your application.

The AST46HA is suitable in a variety of applications, including oil and gas pipelines, well optimization, drilling platforms, CNG/LNG fill stations, paint booths and remote transmitter units (RTU). Moreover, the AST46HA operates at a wide ambient temperature range [-40 to 85°C (-40 to 185°F)], offers a compensated temperature range of” [-30 to 55°C (-22 to 131°F)] and media temperature range of [-40 to 125°C (-40 to 250°F)].
