Feb 16, 2009
American Sensor Technologies' (AST) AST46HA is a media-isolated explosion-proof sensor with digital compensation and single-seal approval.
It is made of stainless steel and is approved to CSA30 (UL1203/FM3615) Class 1, Division 1 and Zone 1 Group IIB Explosion Proof, groups C and D.
The AST46HA is suitable for extreme temperature applications, including arctic environments and off-shore platforms.
It applies digital compensation and utilises Krystal Bond technology.
It utilises a one-piece stainless steel non-oil-filled sensor design, which offers continuous operation at temperatures that cause other sensors to fail.
The AST46HA is suitable for applications where linearity and repeatability are critical.
The AST46HA is versatile and suitable in a variety of applications.
These applications include: oil and gas pipelines, well optimisation, drilling platforms, CNG/LNG fill stations, paint booths and remote transmitter units (RTU).
The AST46HA operates at a wide ambient temperature range -40 to +85C, offers a compensated temperature range of -30 to +55C and a media temperature range of -40 to +125C.
All AST46HA units come standard with +/-0.1 per cent 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.
