SIL2 Rated Pressure Transmitters

The SIL (Safety Integrity Level) certification meets IEC 61508 standards.

The SIL process and rating simplify what systems use to predict failure and system maintenance.  TE offers various products with 4-20mA output signal that meet the IEC 61508 requirements.  SIL2 devices were traditionally used in the downstream oil and gas and chemical process industry, but have seen greater importance in upstream applications to confirm safety and reliability requirements are met. A suffix is added to the end of models requiring the certification. For standard hazardous location ratings and SIL2, the suffix will be "-SL;" example: AST4600A05000P4U1000-SL. If customers require SIL2 and ASME B31.3, the suffix will be "-Y."
