Kyowa KC-60-120-A1-11 L5M2R Concrete Strain Gage
KC-60-120-A1-11 suffixes L5M2R for the gage with a 5 m long vinyl-coated flat 2-wire cable.
Featuring a longer gage length, the KC series gages are wire strain gages suitable for mean strain measurement of concrete under test. Usually, a model with the gage length over 3 times longer than the maximum diameter of the aggregate is selected for the purpose.
