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.

Feature

LED indicate the velocity

no moving parts, free maintenance

various length of sensors can be chose

easy to install

various pipes can use only one type of sensor

the set-point can be adjust continuous

almost no pressure loss

protection grade IP67
