KMC Series Concrete-embedded Strain Gages
The KMC series concrete-embedded strain gages/gauges are designed to measure self-shrinkage and self-stress of cemented materials. They are made of silicone with resistive element made of CuNi alloy wire. They enable measurement of the self-shrinkage and high-fluidity concrete immediately after placing. They are also used effectively to check for cracks of cemented materials. Usually, a T-type thermocouple is installed near the gage, while the KMC series gages of H4 type do not require such the installation since they are equipped with a built-in thermocouple. They are able to withstand strain limits of approximately 0.3% at normal temperature.
