SUMMARY A strain gauge encapsulation and protection system is described which ensures the long term stability of resistance strain gauges. Protected gauges have been subjected to normal outdoor conditions for a period of 2 years together with over 40 temperature cycles to 60°C and 215 strain cycles to 800 micro‐strain. Zero shift has not exceeded 40 microstrain.
