P90S Series Vacuum Switch

P90S Series Vacuum Switch
The P90S features an extremely sensitive silicone on silk diaphragm that senses air or inert gas pressure in fractions of an inch of water. The P90S can be panel mounted to eliminate pressure fittings thereby increasing packaging efficiency, or traditionally mounted via a port fitting. This unit is perfect for use in monitoring exhaust vent pressure.
