4 KSR Magnetic Float Switches are used to control distinct levels of a liquid. They are based on the float principle with individual contacts for every level to be monitored. float with a built-in magnetic system actuates a small reed contact through the wall of the guide tube. Thus the switching operation is without direct contact to the liquid, free of wear and tear, and does not require any power supply. KSR Magnetic Float Switches are available with multiple switch points. Contact denomination always refers to rising level of the liquid: S - closing on rising level O - opening on rising level - change-over y using one float up to a maximum of switch points the switching behaviour is bistable i.e. the switching state will remain the same even when the liquid moves further up or down. Contacts are volt-free. Technical advantages The simple operating principle is suitable for a wide variety of applications. Suitable for virtually all liquids. Measurement of liquid levels independent of physical or chemical changes of the liquid, e.g. foam, conductivity, dielectric constant, S.G., pressure, vacuum, temperature, vapour, condensation, bubbles, boiling effects. niversal signal processing PLC Initiator circuit (NMR) Signal amplifiers/protection relays -point controls S-Interface available, Ex/non-Ex. Multiple switch points in one unit (up to 8). High repeatability of set points. Long service life. Suitable for rough environments. Interface and product level measurement possible at -S.G. 50 kg / m. Simple installation and commissioning, maintenance-free. pplication limits: T = -96 C to + 00 C P = vacuum to 00 bar S.G. 400 kg/m High availability of corrosion resistant materials for applications in all industries: Chemical, petrochemical, and pharmaceutical industry, liquid natural gas, off-shore, ship-building, power plants, manufacturing industry, water treatment, food and beverages. pplication specific designs available. Explosion-proof designs. Float switches are simple devices without certification according EN 5000/5.4. s such, they are allowed to be used in Ex-area Zone, on condition, that they work with a certified intrinsically safe circuit in protection class EEx ib or higher.
