Characteristic

Piston flow switch, Highly reproducible, Insensitive to dirt.

Adjusted switching value descending off point.

It is used to monitor the oil level within the screw compressor.

Functional description

The magnet ring-containing plunger will be pushed out automatically when the flow of the liquid increases, the isolation promoting reed switch located on the on the magnet ring of the plunger is actuated;

When the liquid flow decreases, the plunger regresses under the effect of the spring, which causes the reed switch to break.

The reed switch is completely isolated from the liquid within the valve.

The permanent magnet ring is able to endure high temperature, as well substances like Freon, oil, water, etc.

Installation and connection

Please install in accordance with the flow direction of the liquid, and Make sure that cable outlet points up. When connecting the copper pipe, use one of the spanner to stabilize the valve, and the other spanner to twist the nut. Note that the torque cannot exceed 75Nm.
