Use Cases

Inline Process Verification

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

Machine Displacement Feedback

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.

Test & Measurement

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.
