Functional engineering application
The Air Break / Mobley Water Level Switch is a critical magnetic float-operated safety control designed for steam boilers, feedwater tanks, and industrial pressure vessels. Utilizing a glandless magnetic coupling mechanism, the internal float moves with liquid level changes to trip an external snap-action air-break switch without mechanical seals. This eliminates low-water dry-firing hazards across steam plants in Kenya, Uganda, Tanzania, Rwanda, and Burundi.
Industrial Mobley air break magnetic water level switch for steam boilers, feed tanks, and pressure vessels to prevent dry firing.
