Relay output thermal flow switch sensor FS-E01 for water oil air
The product is on the basis of the principle of thermal, the sealed probe contains two resistors, one is heated, as the detecting resistor, another is not heated, as the benchmark resistance. When the fluid flows, the heat of detecting resistance will be taken away. Resistance is changed. The differential resistance value is used as the basis of flow velocity.
No moving parts, maintenance free, easy installation, a model can be suitable for a variety of pipe diameters. Adjustable setting point of flow switch, extremely low pressure loss, compact structure. LED light shows the flow trend and switch state.
