F31-1**, -2**, -3**, -4** Series Flange mount vertical switch Flange mount for installation from outside of tank II 1 / 2 G D Ex d IIC T4 (Tamb = -50ºC to +100ºC) Ex tD A20/A21 T110ºC IP6X Max Process Temp 100ºC for use in Zones 1 and 2 One, two, three, or four switch levels Switch configurations of SPST or SPDT reed switch contacts for high reliability Enclosure Stainless Steel IP68 All are custom built to suit particular applications, based on information provided The F31 series are vertical float switches that are top mounted, via a flanged connection, from the outside of the tank. Access to the inside of the tank is not required for fitting the float switch. These can be made with either 1, 2, 3 or 4 point level switches of either SPST or SPDT action. The electrical loom is fully insulated and encapsulated within the stem of the device. Designed to withstand the most arduous applications, they are suitable for use in Water, Diesel, Oil and hydraulic tanks and reservoirs, as well as Chemical and Petrochemical storage and process control. The float or floats follow the level of the liquid and operate the SPST or SPDT switch elements within the stem.

Please contact Cynergy3 with your requirements. Information that is normally required: The application and fluid in which the float switch will be used The Specific Gravity, SG, of the fluid The maximum temperature of the fluid Will the float switch be fitted in a tank that is pressurised The required flange size (If unknown we can specify) The distance from the mounting face of the float switch to the switching point or points. The switching action required at the switch points 'make on rise' or ‘make on fall' Email:[email protected] ISO9001 C E R T I F I E D www.cynergy3.com © 2013 Cynergy3 Components, All Rights Reserved.
