Description

Hot Flow Switch Safety Explosion Proof High Precision

Measuring Principle Of Hot Flow Switch

Thermal flow switches are designed based on the principle that the temperature change of the probe produces a difference. A heating element and two thermal sensors are built into the probe, which are in contact with the medium. When the thermal flow switch is working, the heating element emits constant heat. When there is no medium flowing in the pipeline, the heat received by the thermal sensor is a constant value. When there is a medium flowing, the heat received by the thermal sensor will follow. The flow rate of the medium changes, and the thermal sensor converts the temperature difference signal into an electrical signal. When the flow rate reaches a certain set point, the thermal flow switch outputs a switch signal.

Applications Of Hot Flow Switch


Gas-liquid dual-purpose type, can be widely used in industrial automation/mechanical equipment/air compression industry/refrigeration and air-conditioning fields, and industrial applications are specifically used in water-cooled welding machines, laser equipment cooling systems, vacuum coating machines, electric furnaces, polysilicon ingot furnaces, etc. . The water flow switch magnet is not in a flowing waterway and can be used in sewage systems and works properly.
