1 PREURE- TIGHT FAMEPROOF FOR HYDROGEN ATMOPHERE READY FR- eries FOAT TYPE EVE WITCH OUTINE FR- is a float-rod type level switch which applies for wide range of pressure and temperature. FR- is suitable for the monitoring of liquid levels in various process tanks, boiler feeding water, etc. FEATURE Wide selection range for temperature and pressure. Variety of material selection for float and chambers for suitable anti-corrosive capability. Perfect isolation between pressurized part and electric component by magnetic coupling for high reliability and safety. In addition to watertight construction, pressure tight and intrinsically safe versions are ready to meet hazardous application. Especially, pressure-tight flameproof suitable for Hydrogen atmosphere (Ex d IIC T) is available which eliminates the necessity of safety barriers. MAIN APPICATION Boiler Feeding drum water control Fuel oil tank level control Process control for petrochemical plants Water treatment plants Oil rig's platform ealing liquid level control for generators and turbines Other liquid level control
