Strain Analysis using Resistance Strain Gauges Course

The Strain Analysis course provides an introduction to electrical resistance strain gauges and the associated circuits for strain measurement and transducer applications. It covers the installation of foil gauges using cyanoacrylate and epoxy adhesives, inspection of installations, the measurement of strain and load, and the use of rosettes to determine principal values.

The course uses lectures, demonstrations and practical tasks to provide participants with a good understanding of electrical resistance strain gauges, the selection and use of gauges and circuits for strain measurement and transducer applications, the positioning of gauges, and the methods used to install and test gauges and circuits.

Some previous strain gauge experience is desirable.

The Strain Analysis course provides an appropriate preparation for certification at Level 2.

Registration

Please check the upcoming Training and Certification events for dates of the next course.

Hands-on sessions form an important element of the course and it is therefore necessary to restrict the group size to about 8. Because places are limited, please complete the registration form with your details and preferred options. On receipt of your application, the Chair of the Certification Committee will contact you to confirm your registration or discuss with you the options of a future date.

Certification

The measurement of strain through the medium of a strain gauge depends for its success on a proper and acceptable installation of the strain gauge itself. For structural testing, design evaluation and sensor operation the installation of strain gauges is a skilled operation which requires considerable practical ability and know-how on the part of the installer. A poorly positioned or inadequate installation, resulting in erroneous measurements being taken, could turn out ultimately to have disastrous consequences.

The provisions of modern day consumer protection legislation and the requirements of various safety regulations make it necessary for critical measurements on components and structures to be carried out to an approved standard by competent persons who are qualified in the best techniques available.

To demonstrate your competence as a strain gauge user you should hold a BSSM Certificate. The certification scheme operates at three levels and complies with the European Standard EN473:1993. The levels cater for staff with a wide range of competencies and responsibilities, from strain gauge installation to analysis and design.
