Optical low rinse-aid sensor (optional)
The optical low rinse-aid sensor consists of a transmitter diode and
a receiver diode.
A light beam is transmitted from the transmitter diode (A) to the
receiver diode (B) via a prism (C). If the dispenser is full, the light
beam in the prism is scattered. The received signal is weaker than
the transmitted one.
