It's a small electrical device that senses pressure in systems like air compressors, water pumps, boilers, or refrigeration units. It automatically turns equipment on or off (or triggers an alarm) when the pressure reaches certain levels you set.
| Specification | Details |

| Main Range | It works from low pressure (vacuum, like -0.2 bar) up to about 7.5 bar (around 108 psi) |
| Differential | You can adjust the gap between "turn on" and "turn off" pressure (0.7 to 4 bar) |
