Operation
Connect the LVDT Adapter to your SIRIUS or DEWE43 channel and connect to SENSOR input your sensor probe.
Adapter setting, frequency, phase
Depending on the sensor used select excitation frequency of the adapter as close as possible to frequency in
sensors specifications.
With phase compensation adjust the measured output to maximum output value.

Connections
LVDT – Differential
Half-Bridge LVDT
*
6-wire connection only shown. 4-wire also possible, connect Sns and Exc signals on adapter side of connector.
* Input - (pin7) shall be connected to half bridge completion resistor divider assembled with discrete resistors with the following recommended
specifications: Resistance 1kΩ, Tolerance 0.1%, Temperature coefficient 15ppm, Power 0,125W. This connection is preferred over the previous
connection IN- to GND (so called “noisy GND”).
