Float Level Sensors
Magnetic Float Level Sensors with Reed Switches (series)
SHR’s float level sensors use hermetically sealed magnetic reed switches inside plastic or stainless steel stems. As liquid level rises or falls, the magnet-equipped float moves along the stem and actuates the reed contacts — delivering millions of dependable on/off cycles for liquid level control.
