                                         Thermal conductance Flow Switch RTF

Product Description

RTF thermal conductivity type flow switch is based on the principle of heat exchange design, the heat conduction of the flow switch and the measured fluid flow rate are closely related, if no medium is flowing in the pipeline, the heat received by the thermal sensor is a fixed value, but when the fluid medium flow overflow switch when the probe is to heat as measured by the thermal sensor with the changes in the flow rate of the medium varies, then this temperature differential signal is converted into an electrical signal, the built-in A / D processing circuit will set the flow and the instantaneous flow rate, compared to output contact signals. Trends in thermal conductivity flow switch integration for the flow probe and signal processors, six LED indicators provide a flow state switch action value can simply protect the screw potentiometer on the front panel to adjust the switch output form.
