American Sensor Technologies, Inc. (AST) offers 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 Proof, Groups C and D, the AST46HA is the cost effective solution for extreme temperature applications, including arctic environments and off shore platforms. By applying digital compensation and utilizing Krystal Bond Technology, this product offers top performance in the most extreme temperature conditions. 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 that cause other sensors to fail. If linearity and repeatability are critical for your application, this product will exceed your expectations at an affordable price.

The AST46HA is extremely versatile and suitable in a variety of applications. These applications include: 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)]. All AST46HA units come standard with ±0.1% BFSL accuracy, EMI/RFI protection of 100V/meter and a variety of output options including 4-20mA, 1-5V, and 0.5-4.5V ratiometric.
