Pressure sensor switch To/in - a design and the principle of functioning

The principle of functioning of the sensor switch of pressure To/in

1 — Shtyrevaya the plug
2 — Contact points
3 — the Directing pin

4 — the Pusher
5 — the Disk spring of a high pressure
6 — the Disk spring of low pressure


The sensor switch of pressure is switched on in the line of a high pressure of a receiver dehumidifier and serves for shutdown of the K/V compressor at excessive increase or pressure drop in the line.

So lowering of pressure in the high-pressure line is lower than 177 kPas the sensor switch perceives as a signal of development of leak of coolant and stops the compressor in order to avoid irreversible losses of a working body, excessively high pressure in the line (over 2940 kPas) can lead to destruction of components of a refrigerator path and also demands shutdown of the compressor.
