Very high temperature operation. Sensors extend the maximum use temperature from the current capability of 600 o C to at least 1100 o C. Versatile. Sensors can be designed for either dynamic or static strain measurements, can have various patterns and gauge resistance. Sensors can be fabricated directly on the test parts or can be on a metal shim which is then attached to the test articles. Highly stable and repeatable.
Sensors can be mass produced using integrated circuit based device fabrication technology.
These sensors can al.so be utilized and integrated as pressure transducers and high temperature extensometers. No other gauge currently exists or is being marketed that can provide minimally intrusive strain measurement at such high temperatures with the accuracy and repeatability that these sensors offers. An electrical resistance strain gauge is a strain sensing element whose electrical resistance changes in response to an applied strain. Knowing the strain sensitivity of the gauge, one can determine the applied strain from the change in gauge resistance. As the operating temperature increases, however, the problems associated with this type of gauge also increase.
