Fire-fighting equipment
Amenics FF5-8 series of pressostats are suitable for a wide range of industrial and commercial applications. Their functions, as pressure switches, limiters or cut-outs can be utilized for:
· Monitoring and controlling the pressure of liquid orgaseous media in pipelines, tanks,vats,pressure vessels and apparatus.
· Duties in process control, cooling,pneumatics and hydraulics.
· Automatic switching of pump motorsfor supplying water to dwellings, booster pumps, fire-fighting equipment.
Mode of operation
The pressure of the monitored medium operates against a flat diaphragm, bellows or a plunger(depending on pressure range).A system of levers and springs works on a snap-action cascade switch of high resistance to vibration, ensuring flutter-free switching.
