The second generation Eclipse 705, 2-wire guided wave radar level transmitter is type approved to the European norms for steam drums, EN 12952-11 (water tube boilers) and EN 12953-9 (shell type boilers) as primary and secondary safety device. As a secondary safety device, it fulfills all general control functions on the steam drum; such as the controlling of the hot feed water to the boiler. As primary safety device,it operates as a safety switch. The transmitter combines reliability,repeatability and an efficient process seal. It uses the technology of guided wave radar to measure independently of process parameters such as density, conductivity, dielectrics, pH. The device resists a process pressure of 155bar at an equivalent temperature of 345°C in saturated steam applications. For non-steam applications, it can be used inprocess conditions from –196 up to 430°C /full vacuum up to 430bar. The transmitter can be configured for both measuring level and liquid-liquid interface in level units or volume units. It is available as a SIL2 version offering a SFF (Safe Failure Fraction) of 91%. It is suitable for SIL2 loops as 1oo1 device and allows for Fieldbus, AMS ,Hart,FDT/PACTware communication.
