Abstract

This paper presents a system for the measurement of transient strains in steam-turbine casings. The components of the measurement system have been tested in turbine environments of 500° C and and 1000 psi. The life and accuracy of the gage are reviewed, the many pitfalls discussed and a sample of test results is presented to substantiate the accuracy of the system.
