Is the BarScreenSensor also suitable for coins?

No, we recommend the BarScreenSensor only from a weight of 100 grams and coins do not normally reach this value. If the test objects are too thin, the path length of the ultrasound is not long enough to perform a sufficiently precise measurement.
The GoldScreenSensor which can test smaller objects like coins and bars up to 100 grams, is an excellent addition to the BarScreenSensor.
