Aquasensor

New-generation dishwashers come with a number of
standard programs, as well as with additional programs and functions. One of these is a rinse automation that is controlled by an integratedoptical sensor.

One of these is rinse automation that is controlled by an integrated optical filter. This results in an optimal setting for the duration and water consumption and so in energy savings.

An optical sensor consists of an infrared photodiode and a phototransistor facing each other on the same board. The board is protected by a casing. An infrared beam is emitted by the photodiode and captured by the phototransistor.

If the water is clean, a signal is sent to the control board, resulting in a change to the rinse program: clean water is reused instead of adding new water, and the additional rinsing of the dishes is stopped.

If on the other hand the water is soiled, the beam intensity is insufficient to trigger the phototransistor. In this case, the microprocessor of the optical sensor system sends information about the lack of a system from the phototransistor to the control module.

An optical sensor can save up to 4 liters of water per washing cycle without affecting the quality of the washing.
