Thermal Flow Switch - China

price: contact company for price

VF-S Thermal Flow Switch is based on the theory of heat exchange. Heat

and thermal module is built inside the probe. The heat conductivity rate

of the device is closely related to the flow rate of media. If no media

flows through the pipe, the thermal module gets the fixed heat quantity

from the heat module. While there is flowing through the probe, the

thermal module gets the heat quantity which varies with the flow speed.

The thermal module converts the differential temperature signal into

electric signal .Then the signal processor exports 4-20mA current signal

or the signal of the switching point. It provides display, transmission

control and remote monitoring in one unit. Operating range: Water: 0-5

m/s Oil: 0-10 m/s Air: 0-100m/s Operating voltage:
