Thermal flow switch FS211

for waterfor oilfor gas

Principle Structure: There are two resistors in the enclosed probe based on the thermal principle. One of them is heated as the detection resistor and the other isnot heated. As the reference resistance, when the medium flows, the heat on the heating resistor is taken away. The resistance value is changed, the two resistance differences are used as the basis for judging the flow rate. Features: No moving parts, maintenance-free, easy to install, one type can meet a variety of diameter requirements. Switching value is continuously adjustable, very low pressure loss, compact structure, LED display flow trends and switch status. Application: Gas-liquid dual-use type, used for pneumatic and hydraulic systems, circulating water, cutting fluidand lubricating oil flow monitoring, and pump idling protection.
