FCI provides pressure switches that include a hermetically sealed sensing element and integral or remote electronics that provide indication of pressure above or below a predetermined threshold at the sensing location. The pressure element is directly installed into pipes, ducts, tanks, reservoirs, sumps and gearboxes on commercial and military aircraft, spacecraft, vehicles and marine applications. It can be specified to indicate absolute, gauge or differential pressure values as required for the customers application
