Features
Spring-free magnetic toggle structure, vibration resistant, no contact chatter or sticking, high stability in boiler conditions. Hermetically sealed package, contacts fully isolated from process media, moisture and steam cannot corrode contacts. Magnetic coupling drive, no mechanical linkage through pressure vessel, eliminating external leakage risk. Independently replaceable mechanism; when float body is intact, only SK50 needs replacement to restore level switch, reducing maintenance cost. Suitable for normal and boiler hazardous conditions, with explosion-proof housing available for hazardous areas.
Applications
Power plant boiler drum water level monitoring, pressure vessel high/low level alarms, pump start/stop control, petrochemical tank farms, water treatment pressure vessel level interlock protection.
