3.4: Sensor Variables
You can read out internal device data with this parameter group. The displayed values
depend on the respective application. You can access the following data:
3.4.1: Raw Value (for service purposes only)
Distance from the flange to material
The measured distance from the flange to the surface of the material.
3.4.2: Echo Amplitude
Measure of quality of reflection
This dimensionless value is an absolute measure of the strength of reflection at the
material. Its display can be evaluated as follows:
• x > 1:
• 1 > x > 0.5:
• 0.5 > x > 0.05: satisfactory
• x < 0.05:
