Typical installation with bonding to metal surface for use in relatively well conditions such as in laboratory and short term period.
Typical installation onto a metal surface for use in harsh conditions, such as under water for a long period or onto a reinforcing bar to be embedded into concrete.
Concrete surfaces
Gauges are typicallly installed onto concrete structures or concrete specimens for loading tests. Strain gauges with an integral lead do not require lead wire connection with connecting terminals.
Weldable strain gauges
These gauges are typically installed by spot-welding onto metal surfaces for use in harsh environments, such as on engines, heated turbines, or field sites for long periods.
