2.3.5 Sensor
diagrams
Sensor diagrams are available for determining the admissible measuring range depending on the
gap between transmitter and receiver (Ax) and the material. Ax is specified as follows:
Fig. 1: Transmitter-receiver gap Ax
The marked areas represent the working ranges of the sensors. For all combinations of sheet
thickness and sensor distance Ax within the range a double sheet condition will be reliably
detected, if the switching thresholds are set “tight”.
The working ranges of the sensors depend very much on the material properties, they can deviate
from the sensor diagrams shown below.
Note
The stated measurement ranges are only valid for units of type
„Standard“. For details refer to chapter 3.2.
