The SMFC1 (Self monitoring float control) in combination with the float switch BA75-1 is a failsave self-monitoring low level limiter for steam generators according to TRD 602 or 604. During the periodic and automatically controlled functional test the float device is lowered beneath LWL via a magnetic coil and the correct function of the LWL controller is tested.
Function BA75-1The water level controller is a float actuated unit. The transmitter magnet connected with the float via the float rod actuates without direct contact the magnetic switch in the switch housing. The float device is equipped with additional displacement elements to facilitate the buoyancy. These displacement elements move together withthe transmitter magnet in a mercury filling.
The product according to PED directive 97/23/EEC annex VII (module B+D, Category IV), 89/336/EWG, 73/23/EWG has the CE-mark no. 0035 of the notified body. Applied rules as per TRD/AD2000/Wasserstand 100 or ASME Boiler.
