There are basically 2 capacitors, 1 coil and an inverter circuit on itself or the control
system to which it is connected.
Pressure increase pushes a ferrite part inside the sensor into the coil. Therefore L
(inductance) value of coil winding changes and the output value of the sensor
–
inverter system changes. Therefore pressure value can be measured in an analog
manner.
The amount of water to be taken in for the programs is controlled by the water
meters. Water level sensor serves the basic functions of deciding to take in water
again, control the heater safety level, door opening level or foam level.
Also, if there are any error in the water meters or its connections, water is taken in
with the water level sensor.

Cable inputs
5VDC / Data / GND.
Operating Voltage : 5 VDC
When it is empty, 625 ± 2 Hz frequency value should
be read from the Data and GND terminals.
