Advanced Strain-Gage Pressure Transducer.

Gould, Inc. has developed new strain gage deposition and lead wire attachment processes that have shown significant promise for improved accuracy, higher reliability, and lower cost when applied to strain gage pressure transducers now being used in gas turbine control and diagnostic systems. This report summarizes work efforts to experimentally identify and to validate, via bench tests, the benefits of these new fabrication processes. The results of static accuracy, temperature and pressure cycling, acceleration, vibration, thermal and mechanical shock, and humidity testing are discussed. Author
