K-TEK”s MT5000 Series of guided-wave radar transmitters have been certified for use in SIL2/3 (Safety Integrity Levels 2 and 3) applications. To obtain SIL certification, the products must be analyzed based on quantitative data and tests, indicating the length of time between failures and expected performance in the field. This certification emphasizes quantitative measures for reducing risk at the process measurement level when implementing Safety Instrumented Systems (SIS) in process plant environments. The MT5000 devices feature an integrated graphic display for quick and easy viewing of waveform screens. The user-friendly setup menu supports a wide range of languages for fast setup in virtually any region of the world. A concentric waveguide directs the radar beam, alleviating divergence problems and echoes from tank walls and surrounding structures. In addition, the devices are unaffected by variations in specific gravity, and accurate level measurements are provided even with widely varying temperatures and pressures: up to 5000 PSI (344 bar) or 800 F (427 C). The two-wire, loop powered design reduces wiring costs and provides a strong signal over distances.
