Thermal Flow Switch
1) Range 1…150cm/s(water )，3…300cm/s(oil)，20…2000cm/s(air ).
2) Signal output:PNP,NPN, Relay Normally Open + Normally Closed (SPDT)
3) Power supply:24V±20%DC or 230V±15%AC
Application
Pneumatic and hydraulic dual purpose, low flow rate alarm, can be used for pneumatic and hydraulic systems, can be used for circulating water, cutting fluid and lubricating oil cut-off detection, and pump idling protection.
Product Details
Based on the thermal principle, the sealed probe contains two resistors, one of which is not heated as the detection resistor, the other is not heated as the reference resistor. When the medium flows, the heat on the heating resistor is taken away, the resistance value is changed, and the difference between the two resistors is used as the basis to judge the flow rate. No moving parts, maintenance-free, easy installation, one model is suitable for a variety of pipe diameter requirements, switching continuously adjustable, extremely low pressure loss, compact structure, LED display flow trend and switch status. Most of the components are imported to improve the stability of the products.
