Optical sensors detect temperature, turbidity, conductivity and speed when used in washing machines and dishwashers so as to enhance the washing and cleaning results and to reduce water and energy consumption. In addition to cleaning performance, important information can also be provided for service personnel.

Conductivity sensor

  • Determination of the water hardness in the fresh water
  • Adaptation of the detergent concentration in the cleaning process (auto-dosage)
  • Allergy protection by specific rinsing function
  • Adaptation of the washing program on the basis of the detergent concentration

Rotation sensor for top-loader washing machines

  • Motorized transmission control
  • Transmission unit with speed sensor for top-loading washing machines
  • Switching between washing and spin speed sensing
  • Wear-free and robust operating principle of the optical sensor
