Bestech SIL2-rated pressure transmitters

Bestech Australia has introduced its 4-20 mA pressure transmitters with SIL2 certification for 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 SIL process and rating simplify what systems to 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.

A suffix is added to the end of the models requiring the certification. For standard hazardous location ratings and SIL2, the suffix will be '-SL'; if customers require SIL2 and ASME B31.3, the suffix will be '-Y'.
