As an aviator, I’ve always found interest in aerospace applications of strain gages.  Strain gage use in testing aircraft goes way back to the 1940’s...

Load cell (tension bending, compression, shear, etc.) is a transducer (physical element) that converts mechanical force into electrical signal. There...

Jim Johnson speaks briefly about the high-quality tools required to perform a good strain gage installation. Many of these tools are found in the ATS...

CD-Series Crack Detection Gages are designed to provide a convenient, economical method of indicating the presence of a crack, or indicating when a...

Resistance thermometry is a widely employed method of measuring temperature, and is based on using a material whose resistivity changes as a function...

The Micro-Measurements Cable-Extension Displacement Sensor provides a voltage signal linearly proportional to the extension of a retractable...

Intense, time-varying electromagnetic fields with steep gradients in field strength can cause troublesome noise in strain gage circuits. In severe...

The purpose of surface preparation is to develop a chemically clean surface having a roughness appropriate to the gage installation requirements, a...

Degreasing is performed to remove oils, greases, organic contaminants, and soluable chemical residues. Degreasing should always be the first...

Concrete surfaces are usually uneven, rough, and porous. In order to develop a proper substrate for gage bonding, it is necessary to apply a leveling and sealing precoat of epoxy adhesive to the concrete, typically M-Bond AE-10. Before applying the precoat, the concrete surface must be prepared by a procedure which accounts for the porosity of this material.
