FCI switches receive SIL-2 compliance rating from TUV Nord
San Marcos, Calif., January 22—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 classified 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.
FCI’s new SIL-2 safety compliance ensures its customers that the third-party testing organization (TUV NORD) has tested the FLT93 Switch Series, and when the product is in use, the process risk is reduced to the designated level.
The advanced FlexSwitch FLT Series monitors flow, level or interface and can perform flow and level sensing simultaneously. The Flow/Level (FLT) Flow Switch monitors the flow, level and interface of liquids, gases, slurries, syrups, lubricants, coolants and more. It is ideal for tank level monitoring and pump low-flow protection applications. This instrument is designed for heavy-duty industrial environments, pump protection and small process connections.
Applications for these switches include pump protection for low flow levels and empty pipe, wet/dry detection, sump level detection, high/low level alarm and control, interface control in separation vessels, foam and sediment interface control, and agitation detection.
It is suitable for use in hazardous (FM, CSA and ATEX classified) locations and is rated for NEMA Type 4X (IP66) environments.
