| Abstract: | Different techniques in commonly used piezoelectric manganin gauge measurement with constant current supply are briefly discussed, along with their advantages and disadvantages.A new method with higher fidelity and accuracy by using digital oscilloscope is introduced, which can improve not only the accuracy in pressure measurement, but also extend the applicable pressure range for the small resistance gauge to as low as 0 17 GPa. |
