The Bonded Strain Gauge Sister Bar is designed to be used for monitoring strain changes in concrete structures.
With the optional thermistor they can also be used to monitor temperature gradients of concrete during or after curing. Typical applications include: reinforced or unreinforced piles and mass concrete,
monitoring strains in reinforcing bars during construction, pile testing, and service life,
monitoring of strain due to load and induced strain during testing diaphragm and slurry walls,
monitoring of bridge and dam construction.
