Get couponsElectronic flow and temperature switch-SN12B
Product introduction
Based on the thermal principle, the sealed probe contains two resistors, one of which is heated to act as a detection resistor and the other unheated to act as a reference resistor. When the medium flows, the heat is carried away from the heated resistor and the resistance value is altered, with the difference between the two resistances being used as a basis for determining the flow rate. No moving parts, maintenance-free, easy to install, one model for a variety of pipe diameter requirements, switching volume continuously adjustable, very low pressure loss, compact structure, LED display flow trend and switching status.
