Lion Precision - Micro Displacement Measurement and Linear Position Measurement Application Notes

St. Paul, MN USA - Micro displacement measurement at the submicron and nanometer level is the primary application for non-contact capacitive sensors and eddy-current senors. To help engineers and other users make those measurements with the best possible results, Lion Precision has expanded its growing technical library to include application notes on linear displacement measurements and position measurements for each sensor technology. While each application may be measuring deflection, deformation, vibration or similar characteristics, teh measurements are fundamentally a measurement of changing position or displacement.

Making measurements at the submicron and nanometer levels requires special care and these application notes discuss the fine details of making such precise measurements. Information includes probe mounting considerations, variables that cause displacements of critical components, calculation of micro-displacements from voltage or digital outputs, thermal effects and other environmental considerations.

The Application Notes are available as web pages and PDF documents and can be found here:

In 1958, Lion Precision was the first company to provide capacitive displacement sensors to industry. The company has expanded its product offering to include eddy-current displacement sensors and some application specific sensors for the machine tool, packaging and PCB industries. The company is focused on assisting users in sensor implementation by providing technical knowledge resources, expert guidance and optimized systems including custom designs.
