Broad offering of sensors based on LVDT technology (Linear Variable Differential Transformer) for measurement of linear displacements.

The sensors are offered in gagehead configuration (also known as pen-probe or pen-type sensors), in captive-core configuration (also known as guided-core) and in open-core configuration.

Some models have spring extended plunger; others are available with air-extended spring return plunger

The LVDTs are available with AC output (tipically used with signal conditionners or compatible equipments), DC output, current output or digital interface.
