Page 4: Regulation Use
MM series, NBK-transmitter options 4 Regulation Use Kobold level transducers are used for the continuous level indication and level control of all kinds of liquids. The simple design with only one moving part (the float) is suitable for applications that demand reliability. Kobold level transducers allow the continuous level indication and level control of liquids unaffected by electrical conductivity, temperature, pressure. -
Page 5: Operating Principle
The Kobold-liquid Level Transducers model MM consist of a tube around which a float travels with inserted magnet, like the Kobold level float switch model M, models without float around the tube, the float is placed in an adjacent bypass tube to actuate the reed chain contacts inside the tube. -
Page 6: Maintenance
MM series, NBK-transmitter options 9 Maintenance In liquids that can cause deposits, the float has to be cleaned at regular intervals. In this case the measuring tube and float should be cleaned from such deposits (valid for models where float is directly guided on the reed chain). Other maintenance jobs are not required. - Page 7 MM series, NBK-transmitter options Model LCD touch screen (KMDFON) Exi Option D (MM): Version with display model D: 14,5…35 Vdc Ex ia parameters: Ui:30 Vdc, Ii:100 mA, Pi:0,75 W, Li:10uH, Ci:15nF Model LCD touch screen + relays (KMDFON) non Ex Option R (MM): Version with display model R: 14,5…35 Vdc...
