American Sensor Technologies Offers SIL2 Certified 4-20 Pressure Transmitters with Hazardous Location Ratings for Upstream/Downstream Applications


American Sensor Technologies (AST) has received SIL2 certification for its 4-20mA pressure transmitters with hazardous location ratings including explosion-proof, intrinsically safe and non-incendive areas. The SIL (Safety Integrity Level) certification was conducted through Exida and meets IEC 61508 standards.



The following products are available in SIL2 configurations:

• AST4300 Non-Incendive Pressure Transmitters

• AST43LP Non-Incendive Pressure Sensor, Class 1 Div 2 Groups A, B, C, D

• AST4400 Intrinsically Safe Pressure Transmitter

• AST4401 Intrinsically Safe Pressure Transmitter, Groups A and B

• AST44LP Class 1, Div. 1 Intrinsically Safe, Low Pressure Transmitter

• AST4500/4510 Submersible Pressure Sensor, Intrinsically Safe, Class I Div 1, Groups C and D

• AST4520 Flush Diaphragm, Non-Clogging Level Sensor/Transmitter

• AST4530 Submersible Pressure Transducer for Chemical Tank Level

• AST4600 Explosion Proof Pressure Transmitters, CSA Class 1, Div. 1



The SIL process and rating simplify what systems use to predict failure and system maintenance. SIL2 devices were traditionally used in the downstream oil and gas and chemical process industry, but have seen greater importance in upstream applications to ensure safety and reliability requirements are met.
