170710 Analog ultrasound sensor<br />
2/2<br />
The sensor is protected against reverse polarity.<br />
The sensor output supplies an impressed current and is loaded during short-circuit operation.<br />
Ideally, the output should be loaded with a resistance of R L =0Ω.<br />

The oszillations at the beginning and the end of the characteristic curve are caused by<br />
the type of sensor construction.<br />
For the characteristic curve displayed, the distance between the sensor and the bottom<br />
of the container was adjusted to 330 mm.<br />
