    An LVDT does not use the reference input. It does require an excitation source that may be supplied on-board or from an external source. An LVDT generally requires some scaling to make full use of the dynamic range of the ERES35105. In order to facilitate this, the signal path allows the addition of gain. Contact RTD Tech Support for more details. FEEDBACK HI...
