Thermal Flow Sensor-3220 Principle & Structure

3220 type thermal flow sensor, based on thermal principle in closed probe contains two resistors, one of them is heated as a detection resistance, the other is not heated as a benchmark resistance, when the medium flows, the heat on the heating resistance is taken away, the resistance value is changed, the two resistance differences are used as the basis for judging the flow rate. 3220 type thermal flow sensor, based on thermal principle in closed probe contains two resistors, one of them is heated as a detection resistance, the other is not heated as a benchmark resistance, when the medium flows, the heat on the heating resistance is taken away, the resistance value A ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u në a ye tɔ̈u

Ajuiɛɛr

3220 ye digital thermal flow switch ye looi në thermal exchange principle. Probe built-in heating module and heat sensing module, flow switch's thermal conduction is closely related to the medium's flow speed, when measured, heat is emitted by the heating module, if there is no medium flowing in the pipeline, then the induction module receives the heat is a fixed value.
