Pneumatic Switches
The Moniteur Sentinel VPT is available with
pneumatic switches for applications requiring
pneumatic signaling. Features and benefits of
the unit:
> The pneumatic switches withstand air and
inert gases and can handle pressures up
to 120 psi.
> Compact switch design (using the V3
pattern) allows easy cam setting.
> Full range of Moniteur visual
indicators is available.
> Flat cover with no external plastics
available.
SW1 SUPPLY SW2
for hazardous areas
Principle of Operation
> Three ports are provided on the back of the switch housing, labeled SW1, SW2, and Supply. The
pneumatic pressure input is connected to the "Supply" port. Inside the housing, the supply pressure is
connected to both of the switches (SW1 and SW2). When either of the switches are tripped, the
pneumatic path is opened and the switch provides output to either the SW1 or SW2 port, depending
on the switch tripped.
> To set the switches, simply adjust the touch-set cam in the same fashion as standard Moniteur units.
> Note: Output air is for signal pressure only.
