This Flow Switch has a 316L Stainless Steel Field Wireable Connection Head - Back Entry housing with DPCO / DPDT (2x Form C) , volt free contacts. It has a maximum switching current of and can be used for switching multiple voltages in AC or DC. Utilising proven dry contact switch technology allows them to be used across a wide temperature range whilst providing output signals suitable for PLC monitoring and/or driving beacons or sounders where the 24A in-rush capability ensures that the switch can safely handle any start-up current surge.
The FL-A Series flow switch is a robust paddle type design utilising stainless steel 316L wetted parts guaranteeing long life. Designed to be mounted in horizontal pipework this switch model is supplied without a tee so it is ready to screw the switch unit directly into an existing 1" BSPT process connection.
FL Series are fully compatible with our battery powered Euroswitch Wireless Technology to enable transmission of condition monitoring and alarm signals in mesh networks and via IoT protocols such as SigFox in all applications including hazardous and explosion-proof environments.
