Product brief introduction
Thermal flow switch is based on the principle of heat exchange design, probe the built-in heating module as well as the thermal module, heat dissipation of heating module and the flow velocity is closely related to the body. If there is no medium flow in the pipe ,thermal circuit receives a fixed value, when the fluid flows through the probe, thermal circuit receives the signal changes over medium velocity, thermal circuit will convert the temperature difference signals of heating module and thermal module into electrical signals, the processor will convert it into PNP/ NPN/ Relay signal output, etc.
LED indicate the velocity
No movable parts, free maintenance
Various length of sensors can be chose
One type for various pipe diameter
Continuously adjustable switch value
Almost no pressure loss
Overall protection grade IP67
