LVDT/RVDT signal conditioner LVDT/A and LVDT/D


The model LVDT/A or LVDT/D signal conditioner provides a convenient and flexible solution to the measurement of displacement or position (linear or angular) when using Linear Variable Differential Transformers or Rotary Variable Differential Transformers (LVDT's or RVDT's).

The analogue amplifier device can be powered from an AC (model LVDT/A) or DC supply (model LVDT/D), and can provide the excitation needed by the attached transformer.

The excitation frequency can be selected from 5 options between 1 and 5 kHz and the conditioned signal can be output via a bipolar voltage channel or via a current loop channel, both being provided as standard.
