The contact pressure gauge allows to visually check the pressure in the cylinder on which it is mounted.
The built-in contact is electrically connected to the extinguishing control panel (ECP).
The pressure gauge contact is open when the pressure is equal to the nominal pressure of the cylinder. The contact closes when the pressure falls below the switchover point.
The contact pressure gauge is designed to be mounted on vibration-free units.
The contact pressure gauge is designed to be fitted and removed safely when the cylinder is pressurized.
