Model FM, HM - Side Mounted Float Sensor

General Description

The FM series, side-mounted level sensors, are manufactured specifically for level detection in clean liquids such as oils, water and chemicals. They are designed for horizontal mounting in a tank or vessel through flanged or threaded connections. To suit many different level sensing

Operational Description

The FM series contain a hermetically sealed reed switch within the stem or flange and a permanent magnet in the end of the shaft. As the float rises or falls with the liquid level, the magnet activates the reed switch. Changing the mounting orientation can reverse switch action. They work well as high or low level alarm or control for light-duty applications. The FM series can be used in any non-hazardous tanks or vessels. However they can be used in hazardous location by connecting with intrinsic safety barriers. (Local approval for the combination system use of Intrinsic Safety standard is required.)
