KSR Magnetic Float Switches1003-5KSR Magnetic Float Switches are used to control distinct levels of aliquid. They are based on the float principle with individual contactsfor every level to be monitored.A float with a built-in magnetic system actuates a small reed contactthrough the wall of the guide tube. Thus the switching operation iswithout direct contact to the liquid, free of wear and tear, and doesnot require any power supply.KSR Magnetic Float Switches are available with multiple switchpoints.• Contact denomination always refers to rising level of the liquid:• S - closing on rising level• O - opening on rising level• U - change-over• By using one float up to a maximum of 2 switch points theswitching behaviour is bistable i.e. the switching state will remainthe 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 ofapplications.• Suitable for virtually all liquids.• Measurement of liquid levels independent of physical or chemicalchanges of the liquid, e.g. foam, conductivity, dielectric constant,S.G., pressure, vacuum, temperature, vapour, condensation,bubbles, boiling effects.• Universal signal processingPLCInitiator circuit (NAMUR)Signal amplifiers/Protection relays2-point controls• AS-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 possibleat ∆-S.G. ≥ 50 kg / m 3 .• Simple installation and commissioning, maintenance-free.• Application limits:T = -196 °C to + 300 °CP = vacuum to 100 barS.G. ≥ 400 kg/m 3• High availability of corrosion resistant materials for applications inall industries:Chemical, petrochemical, and pharmaceutical industry, liquidnatural gas, off-shore, ship-building, power plants, manufacturingindustry, water treatment, food and beverages.• Application specific designs available.• Explosion-proof designs.• Float switches are simple devices without certification accordingEN 50020/5.4.As such, they are allowed to be used in Ex-area ‘Zone 1’, oncondition, that they work with a certified intrinsically safe circuitin protection class EEx ib or higher.4
