Conclusions
-
1.
Some methods of eliminating leakage current in strain gauges have been considered, which involve introducing an antishunting screen within the bonding agent.
-
2.
Various styles of strain gauge with antishunting screens have been discussed, together with suitable circuits. A method has been suggested for calculating the error of a strain gauge with a screen, and formulas have been derived. An experimental test has been performed on the effect from an antishunting screen for a high-temperature platinum film strain gauge.
