There is no standard solution and it cannot be guaranteed that the sensor will be able to measure through the glass in every application.
The glass delivers a certain amount of energy back to the sensor. If this energy is sufficient to detect a signal, the sensor will output the distance.
There are some adjustment points which can be tested in the application.
Adjustment points | Description |
|---|---|
Speed | One option may be to adjust the speed settings of the sensor. The slower the sensor is set, the more measurements are integrated. This leads to a more accurate result. However, it can also lead to a too high energy level of the glass. The optimal setting depends on the glass. Faster can provide better results in this case. |
Distance to the glass | Moving the sensor further away from the glass might help as well. |
Tilt | It is important that the tilt is chosen in such a way that the reflection of the glass is not directed into the transmitter of the sensor. A downward tilt will therefore not bring as much as an upward tilt or a tilt to the right or left. |
However, the individuall points must be checked in the application on site to find the best settings.
There can be two effects that should be considered as well:
If the glass is dirty, it is possible that enough energy is reflected back from the glass.
Sensor detects the glass as an object -> the energy reflected back from the glass exceeds the energy of the object.If the target does not reflect back enough energy (note the energy loss of the glass), the sensor cannot detect the object anymore (maybe it detects the glass as a result).
