6 Analogue output signals
Each channel’s output sign al is a ±5 VDC analog voltage. The output voltage is proportional to the probe-target
gap. As the probe-target gap increases, the voltage becomes more positive. See the included calibration
certificate for specific information.
Interpreting the Output Voltage
Output voltage change for a given change in the probe-target gap is called sensitivity. The sensitivity of the
sensor is listed on the calibration certificate.
Change in gap calculation:
Gap Change = Voltage Change / Sensitivity
For example: With a sen sitivity of 1V/2 μm and a voltage change of +3 V, the probe -target gap has increased by
6 μm.
7 Probe mounting
When multiple probes are mounted together, they must be separated by at least 3 probe diameters to prevent
interference between the channels. The area within 3 probe diameters to the sides and 1.5 diameters behind
should be kept clear of any metallic objects other than the object to be measured. Otherwise, custom calibration
will be required. If this is not possible, field calibration may be required.
8 Extension cables
Sensors which are calibrated with a probe extension cable must be operated with the extension cable installed to
meet specifications. Operating without the extension cable will result in inaccurate measurements.
