Analog Output
Analog outputs can either be used for distance or thickness measurements. Only one
type of measurement can be transmitted at any given time. The analog output has a
resolution of 16 bit.
Output signal
Distance 1, 2
/ Dis-
tance 3 ... 6 /
Difference 1 - 2
/ Diffe-
rence 1 - 3 up 5 - 6
With the distance measurement program
only Distance 1 can be measured
Output range
4 ... 20mA / 0 ... 5V /
0 ... 10V / -5 ... 5V /
-10 ... 10V / inactive
Either the voltage or the current output on
the controller can be used at any given time.
Scaling
Standard scaling
Distance measurements:
scaled to 0 ... measuring range
Thickness measurements:
scaled to 0 ... 2 * measuring range
Two-point scaling
Start of range (in mm):
Value
End of range (in mm):
Value
Output value scaling depends on which measuring program was selected for the rel-
evant output range:
-
for distance measurements: 0 ... measuring range
-
for thickness measurements: 0 ... 2 * measuring range
The first value corresponds to the start of the measuring range and the second value to
the end of the measuring range. If the analog range needs to be moved, we recommend
to use zeroing or mastering.
Two-point scaling enables the user to specify separate start and end values (in millime-
tre) for the sensor's measuring range. The available output range of the analog output
is then spread between the minimum and maximum values. This allows for decreasing
.

Only every n-th value is used (n = 1, 2 ... 1000). All
other measured values are discarded.
