                name£º400 Series the UE mechanical pressure switch


                Weather series pressure switches have a variety of micro switches and a variety of process connection options, making the 400 series UE pressure switches to meet a variety of different needs.
                Because of its characteristics, the 400 series pressure switches are widely used in the protection and control, industrial process equipment and pumps, gas turbines, compressors, pulp and paper, water and sewage treatment industries.A wide variety of microswitch and process connection options, along
                with a weather-tight enclosure, make the 400 Series an ideal choice
                for most ordinary location applications. Its worldwide use is assured
                with approvals and certifications to agency standards.
                Widely used throughout the process industries, the 400 Series
                provides threshold protection and control for many critical functions.
                Typical installations are found in industrial gas production, energy
                generation including pumps, turbines and compressors, pulp and
                paper, and water and wastewater treatment.
