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
database – add a new target material
to the component database. The target material can not be changed if
33010x is selected for Input → Sensor. When using the EZ1900-ADAP-90
adapter to connect an EZ108x-xx-xx-xxx sensor, select 42CrMo4.
CAUTION
This parameter is important for the linearity of the measurement. Ensure
that the selected material matches to the material of the measuring
object.
Eddy current sensors mounted too closely together influence each other.

situation. In some cases, it is necessary to detune – changing of the
oscillator frequency – one AMS 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 and if an AMS EZ 1000 Sensor with a cable
length of 15 m or 30 m is selected. When using the EZ1900-ADAP-90
adapter to connect an EZ108x-xx-xx-xxx sensor, select No detuning.
•
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
The detection of an open sensor circuit, such as due to a sensor cable
break or missing sensor, is not available if Detune frequency high is
selected.
