Eclipse 705 level transmitter

The Eclipse 705, 2-wire Guided Wave Radar is type approved to the newest European norms for steam drums, EN 12952-11 (water tube boilers) and EN 12953-9 (shell type boilers) as ''primary safety '' and ''secondary safety'' device. These norms complete the PED construction guidelines with functional directives, typical for use on steam drums. As a secondary safety device, it fulfils all general control functions on the steam drum; such as the controlling of the hot feed water to the boiler. In its function of ‘primary safety’ device, it operates as a safety switch and turns off the boiler in a safe way in case an emergency / dangerous situation occurs. The number of primary and secondary safety devices on a steam drum depends on the type of boiler, the manning of the boiler (permanently manned, semi-manned or not manned at all), its process pressure, capacity, etc.
