Thermal Flow and Level Switch Fox SW100

Thermal Flow/Level Switch Fox SW100

Thermal Flow/Level Switch Fox SW100 offers a rugged yet economical flow and level switch for gas, liquid and slurry applications. The Thermal Flow/Level Switch Fox SW100 is also designed for use in hazardous areas. It is FM and CE approved and there are no moving parts.

The Thermal Flow/Level Switch incorporates Thermal Technology that operates on the law that fluids absorb heat. A reference RTD measures the fluid temperature. The Active Element is heated above the fluid temperature and the electronics measures the differential temperature. As flow increases, the molecules of the fluid cool the heated element resulting in a reduction of the temperature differential. An RTD contained in the Active Element measures this differential temperature reduction and the electronics translates this into a flow signal. A single potentiometer is used to set the switchpoint. An SW100 can easily detect liquid level.
