Industry Flow Sensors Water Flow Sensor Flow Switch Relay Output

الوصف

The FCT heat exchange flow switch monitors the liquid flow in the pipeline in real time, provides switch output, and 6 LEDs display the fluid status in real time, which can realize the following monitoring functions: medium reduction/increase flow rate; medium presence/absence; It is suitable for monitoring the fluid velocity and flow cutoff in the pipeline to prevent the idling of the pump. It is widely used in petrochemical, electric power, metallurgy, steel mills, papermaking, food processing, water treatment, battery factories and other industries.

FCT flow switch features:
1. Effectively prevent entanglement.
2. Full waterproof shell design.
3. It is suitable for a large range of pipe diameters, and the set point can be adjusted arbitrarily.
4. The indicator light directly displays the flow change.

FCT thermal flow switch can easily set the flow alarm node, unscrew the protective thread, and adjust the bottom knob with a screwdriver.
Set the flow alarm point. For the flow switch with output form of PNP, NPN and relay, the meaning of LED indication is as follows:
        - Red light on Flow rate below set point (transistor not conducting/relay not operating)
        - Yellow light on Flow rate equal to or higher than set point (transistor on/relay action)
        - Yellow and green lights The extent to which the flow rate exceeds the set point (green lights 1, 2, 3 or 4 are on together with the yellow lights)
