Flow switch range caters for larger diameter pipes and higher flow rates

In addition to inline flow switches, the series now includes paddle type flow switches, including a new stainless steel version. Inline and paddle type flow switches are suitable for installation in both small and large size diameter pipes. The flow switches can be used to control pumps, valves and other control equipment in a variety of industrial processes. Typical applications include pipes in water storage systems, food and beverage processing plants, chemicals and refrigeration/cooling systems. The FSH range of paddle type flow switches includes two series: the FSH10AR and FSHPLC. The FSH10AR series is a general purpose paddle flow switch for loads up to 4A inductive. The switch can be used to control a pump, valve or process via a relay output. If the switch is installed in a pumped system, the device is fitted in the pipe after the pump. The switch is ideal for controlling a circulating or centrifugal electric pump that is providing increased pressure or flow within water systems with storage tanks. The flow switch is designed to be installed in a horizontal pipe with the switch mounted through a side entry. The FSHPLC series works in a similar way to the FSH10AR series, but provides a signal level, volt-free contact for output to a PLC. This switch is also suitable for pipe sizes G1" to G4". The FSH10AR and FSHPLC series are constructed in reinforced polyamide with brass screw mounts and are protected to IP54. Maximum pressure is 10 bar and maximum operating temperature is 100°C.
