8.7. Ntc
It is a component which is used to measure the water temperature inside the drum
and resistance of which decreases when the temperature increases.
When the water temperature reaches to the adjusted temperature, heater is disabled
by means of the heater relay on the card.

8.8. Water Level Sensor
An analog water level sensor which is fed by 5 V voltage is used. This sensor
ensures that the water level is determined instantly with the frequency values which it
generates against the pressure created. There are frequency values corresponding
to the all pressure values. An infinite number of levels can be determined in the
analog water level sensor. Water levels change according to the wash criteria of the
designed program depending on the selected program, temperature and auxiliary
function.
Analog water level sensors are pressure
– displacement inverter components in
general.
Analog water level sensors generate frequency modulation as output.
