FST330 Electronic EX type flow switch

FST330 Electronic EX type flow switch Based on the thermal principle, the sealed probe contains two resistors, one of which is heated as the detection resistance and the other is not heated as the reference resistance. When the medium flows, the heat on the heating resistance is taken away and the resistance value is changed.
