15: PRESSURE SWITCH 1 CHANGE-OVER CONTACT ⅜” BSP M 10A IP65

DESCRIPTION

Pressure switch 1 change-over contact ⅜” BSP M 10A IP65 is realized and tested in our seat. Code 15.
It is used when there is the necessity to organise the distribution through the manifold, in according to NFPA12, which provide the protection of one local or more locals.
It is installed directly on the main manifold and on the system lines where there is the flow, through the translation of a small piston inside the pressure switch (which commutes the contact), it resends an electric signal to the centralized control panel, in order to confirm the pressure inside the pipe and therefore the start of distribution.
