Ranco dual pressure switch, -0.3 – 7.0 bar & 7.0 – 30.0 bar, differential pressure 0.6–4.0 bar / 3.5 bar fixed, automatic, flare 1/4" SAE

The Ranco dual pressure switch provides reliable monitoring of both low and high pressure systems in a single compact unit – perfect for commercial refrigeration and HVAC applications.

Two separate switching ranges:

• Low pressure range: -0.3 to 7.0 bar (differential pressure adjustable: 0.6–4.0 bar)

• High pressure range: 7.0 to 30.0 bar (fixed differential pressure: 3.5 bar)

The automatic reset ensures that the switch automatically returns to its original position after being triggered – for uninterrupted operation .

With the 1/4" SAE flare connection, the device can be quickly and safely integrated into existing systems – without any soldering work.
