SIL Rating Pressure Switches

12/22/2006 4:35 AM

Does anyone know of a pressure switch with SIL2 or better certified rating.

Manufactures will make a statement to the effect that 'according to the MTBF figures this unit is suitable for use in a SIL2 environment' but they will not provide a SIL Declaration of Conformity as they do with pressure transmitters.

Try SOR with Heretically seal (encapsulated) micro-switches.
