Switches rated to high safety standard
Built to comply with process industry precision requirements for flow, level and interface sensing in liquid, gas or foam, Fluid Components International’s FLT93 Switch Series is now rated Safety Integrity Level (SIL) 2 compliant. The SIL-2 compliance rating is designated in the failure analysis report with FMEDA techniques by testing laboratory TUV NORD CERT GmbH. The FLT93 Switch Series has been clas-sified as Type A subsystem in accordance to IEC 61508-1 with a hardware failure tolerance of 0. The Probability of Failure on Demand (PFD) meets SIL-2 capability standards. This instrument is ideal for heavy duty industrial environments (FLT93S), pump protection and small process connections requiring a fast, high-responsive switch.
