Fluid Components International has released a tank level switch that is rated for Safety Integrity Level (SIL) 2 compliance service.
The SIL-2 compliance rating for the Tank Level Switch has been documented in a failure analysis report with FMEDA techniques by the testing laboratory TUV NORD CERT GmbH.
The Tank Level Switch has been classified as a 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.
The switch is said to have an unmatched industry record of superior performance and reliability in rugged industries that include chemical processing, oil/gas refining, nuclear power and more.
Depending on the model chosen, the switch measures tank level or interface up to ±2.5 mm accuracy with a repeatability of ±1.3 mm.
It operates within temperatures from -73ºC to 260ºC and has been hydrostatically proof pressure tested to 240 bar (g).
The switch is also said to feature a FlexSwitch design that can monitor flow and temperature.
The switch monitors the flow, level and interface of liquids, gases, slurries, syrups, lubricants and coolants.
Fluid Components International’s products are distributed by AMS instrumentation and Calibration.
