10.3.5 Configuring an LVDT Sensor
Example: LVDT sensor 50 mm
From sensor data sheet – operating characteristics:
Stroke range ± 1.00 inch
± 25.4 mm
Sensitivity 0.8 V/V/inch
31.5 mV/V/mm (C)
Output at stroke ends 800 mv/V
Non-linearity (% of FR), max. ± 0.25
Input voltage, sine wave 3 VRMS (B)
Input frequency range 400 Hz to 5 kHz
Test input frequency 2.5 kHz (A)
– Sensitivity 31.5 mV/V/mm
– The zero position of the sensor is internally represented as +2,500 mV, therefore the
Offset must be set to 2,500 mV.
– The sensor has a linear output signal with sensitivity and offset.
1. Click on ‘Measurement Sources’ in the Toolbox.
2. Expand the list of ‘I/O Channels’ by clicking on ‘+’ in the MSI 60 Project Tree.
3. Drag the ‘Sensitivity/Offset’ analog signal source from the Toolbox and drop it on the
desired LVDT input channel in the MSI 60 Project Tree.
A ‘Sensitivity/Offset Wizard’ opens.
4. Set the according operation parameter from sensor data sheet for frequency (A) and
input voltage (B).
5. Click ‘Next’ when done.
