Extended
range
factor
Target
material
The standard measuring range of several eddy current sensors can be
extended. Use this list field to select a factor for the range extension. The
available factors depend on the selected sensor (see Input > Sensor). The
standard measuring range is multiplied with the selected factor. Example
with EZ 108x with standard range of 2.0 mm (absolute) and selected factor
of 2.0:
Extended range = Standard Range * Factor
Extended range = 2.0 mm * 2.0 = 4.0 mm
Click the button behind the display field to open the selection dialog for
the material of the measuring object. The measuring object is the machine
part the sensor is facing, such as machine shaft, measuring collar, or
trigger wheel. The dialog lists all materials contained in the components
database. Select the appropriate
material,
and
click
OK
.
See
Section 8.8
how to add a missing target material to the component database. The
target material can not be changed if 33010x is selected for Input > Sensor.
This parameter is important for the linearity of the measurement. Ensure that
the selected material matches to the material of the measuring object.
Detune
frequency
Output
sensitivity
Eddy current sensors mounted too closely together influence each other.
Section 5.5
explains this mounting situation. In some cases, it is necessary
to detune – changing of the oscillator frequency – one EZ 1000 converter.
Use the list field to select a detune level. The available detune levels
depend on the selected sensor (see Input > Sensor). If detuning is activated,
use the calibration method Multipoint calibration. Detuning can not be
activated if 33010x is selected for Input > Sensor.
• No detuning
No detuning.
• Detune frequency low
Use this level to detune, for example, one converter if two sensors
are mounted close together.
• Detune frequency high
Use this level if three sensors are mounted close together. Example
for a three sensor setup:
Converter 1: No detuning
Converter 2: Detune frequency low
Converter 3: Detune frequency high
Select the output sensitivity.
• ISO
Example sensitivity EZ 108x with standard measuring range: 8.0 V/
mm
• API
Example sensitivity EZ 108x with standard measuring range: 7.87 V/
mm
