  • Page 19: Measuring Methods

    Turbimax CUS51D Device description Measuring methods Four-beam pulsed light method The method is based on two light sources and four light receivers. Long-life LEDs are used as monochromatic light sources. To eliminate interference from extraneous light sources, these LEDs are pulsed.
  • Page 20 Device description Turbimax CUS51D 135° backscattered light method The transmitted light beam is scattered by the solid matter particles in the medium. The backscattered beams are detected by scattered light receivers, which are arranged next to the light sources. The turbidity of the medium is determined by the amount of backscattered light.

  • Page 21: Calibration

    Turbimax CUS51D Device description Calibration CAUTION Risk of injury caused by acid or medium • Switch off the cleaning unit before removing the sensor from the medium. The sensor enables measurement in a variety of ways that are adapted to suit the specific measurement problems.
  • Page 22 Device description Turbimax CUS51D 5.4.2 Stability criterion During the calibration process, the measured values returned by the sensor are checked to ensure they remain constant. The stability criterion defines the maximum amount the measured values may deviate during calibration and still be accepted.
