Performance
TrueSense technology is the result of and extensive
research and development effort by GE technolo-
gists around the globe.
Testing and validation in real-world industrial appli-
cations has resulted in a robust commercial design
that meets the test of ruggedness and reliability.
Figures 3 and 4 show two examples of TrueSense
performance.
