Technology overview

LVDT sensors measure linear displacement through a core moving within a coil assembly. Choose the mechanical arrangement for the target connection, such as a free core or probe, and select electronics compatible with the sensor signal. Check travel range, linearity, mechanical conditions and measurement rate for the chosen model and configuration.

Frequently asked questions

Answers to the most common questions about our products and services

A passive LVDT needs suitable excitation and conditioning electronics; specifications depend on the stated excitation voltage and frequency.

Not necessarily. Electrical zero is at the centre of the linear ± range; mechanical travel may extend beyond it.

In a free-core sensor, the machine moves and guides the core. A guided gauge includes a guiding mechanism; match travel and target contact to the application.

No. Excitation drives the transformer, while bandwidth describes the channel’s response to motion. Check both sensor and controller specifications.

No. Passive heads need excitation/conditioning, while other systems integrate electronics. Select the measurement path by family and model code.

Alongside range and linearity, check contact force throughout the stroke and the probe tip. On spring-loaded sensors, such as the documented DTD models, force changes along the stroke. Not every LVDT contains a spring or applies the same force to the part.
