Oil flow switches FSF seriesoil flow switchis mainly used to monitor and control the flow of the medium in pipes. FSF seriesoil flow switchis control switches that directly get signals from the flow of medium. FSFseries oil flow switch can be widely used in foodstuff industry, water-cooling air-condition, petroleum and petrifaction, etc. FSF seriesoil flow switch has lots of advantage, such as simple usage, small bulk, light weight, sensitive and reliable action, and etc. Technical parameter Max. ambient temperature: 80 Max. fluid temperature: 110 Max. fluid pressure: 2.5 MPa Max. working voltage: AC 220V Max. working current: 1A Available medium: R134a, R22, R407C, R404A/R507, oil and mixture of oil and refrigerant.
