S-LVDT S-LVDT, Subminiature, Free Core, Displacement Sensor
Designed specifically for tight spaces, this small LVDT delivers high performance in a small package with longer stroke lengths than our M-Series. Precision-machined components provide a smooth static and dynamic response. Pair with a MicroStrain signal conditioner and optimize for a high bandwidth/response rate or resolution with low temperature drift. Extremely lightweight, spring-loaded cores are tiny, yet rugged. Superelastic, corrosion-resistant alloys provide resistance to kinking and permanent deformation and allow for submersion of the instrument.

Use Cases
Rugged, environmentally insensitive sensors are ideally suited for integration into a multitude of in-line production process verification tasks.
Miniature size allows access to nearly any feature.
Many “standard” features can be customized to fit a specific application:
- custom calibrated stroke ranges
- modified body or core lengths
- hermetic or “pressure-equalized” versions
Miniature sensors allow for integration into complex mechanical assemblies for displacement feedback of mechanical grippers, relative position of targets and closed loop position control.
Adjustable filtering allows for high bandwidth which enables quick feedback and responsive machine control systems.
Multiple sizes, stroke lengths, accuracy, and filter settings provide sensors for every test and measurement application.
Calibrated displacement systems shortens startup time and ensures accurate results out of the box.
Integration with our wireless sensors (V-Link-200 for example) enables rapid integration and the added features of SensorConnect and/or SensorCloud.
