In this instruction manual the reader can get explanation about output, calibration routine, the calibration routine, sensor, and sample. There are many information such as resistor, application, etape sensor, actual characteristics, and level sensor are explained inside the instruction manual.
The instruction manual gives the reader discussion about the etape sensor, circuit, sensor output, voltage divider, and sensor length. Here are taken from the instruction manual:
The Milone eTape liquid level sensor is an innovative solid state sensor that makes use of printed electronics instead of moving mechanical floats. The eTape’s envelope is compressed by hydrostatic pressure of the fluid in which it is immersed resulting in a change in resistance which corresponds to the distance from the top of the sensor to the fluid surface. The eTape can be modeled as a variable resistor (60 – 550 Ω ± 20%). In operation, as the liquid level rises and falls, the measured resistance decreases and increases, respectively. It is important to remember this basic principle of operation: The lower the liquid level, the higher the resistance. The higher the liquid level, the lower the resistance.
Furthermore, this instruction manual tells the reader more regarding theory, sensor circuit, digital voltage, program, and calibration.
