Pressure switch FF4
The pressure-dependent switch of the line FF 4 are suitable for a wide range of applications in industry and trade. They work in ther function as regulators, switches or limiters:
- to monitor and control the pressure conditions of liquid or gaseous media in pipelines, tanks and boilers.
- in process control, cooling, pneumatics and hydraulics.
- to control the pressure in cooling systems and lubrication systems for machinery.
- their task is next to the automatic monitoring and relief, for example, the stabilization of a certain pressure, to initiate and end of different regulation and control operations, the release of functional processes and generate signals.
- Pressure Switch FF 4 are used to separate on and off of motors on pumps and compressors in household water, pressure boosting systems, oil and compressed air supply systems.
