Concrete Compression Testing Sensor CM-H

CM-H Compressometer (Destructive)　
20000 x 10-6 strainCE

The CM-10H compressometer is designed to conduct a breaking strength test. It measures the compression strain on a cylindrical concrete specimen (10 cm in diameter x 20 cm in length) made of generally used concrete or high-strength concrete. The high-sensitivity strain gauge is assembled into this compressometer to measure the amount of strain. Both the high-sensitivity strain gauge and a cylindrical concrete specimen are provided with coverings to protect them from damage. A cylindrical concrete specimen can be set in the compressometer quickly and easily. This compressometer allows the strain on a wet concrete specimen, taken out right after underwater curing, to be measured. With this compressometer linked with either the CLL-NA or CLH-MNA load meter, it is also possible to measure the modulus of static elasticity.

Concrete Compression Testing Sensor CM

CM Compressometer　
50000 x 10-6 strain to 33000 x 10-6 strainCE

The CM compressometer is designed to conduct a strength test. It measures the axial strain on a cylindrical concrete specimen placed in and secured by screws to the inner chamber of this compressometer. It uses a high-sensitivity strain gauge to measure the amount of strain. By multiplying a measurement by a certain factor, the amount of strain can be calculated as a numerical value. Unlike the case of ordinary strain gauges, this compressometer is simple and easy to operate and can be used repeatedly. However, it cannot be used to conduct breaking tests.

Crack Displacement Transducers KG-B

KG-B Crack Displacement Transducer　X:-2 to +4 mm　Y:±3 mm

The KG-B crack displacement transducer is used to measure the displacement in two directions simultaneously: the displacement of openings, such as concrete cracks or joints, and the horizontal shear displacement. It is mounted on a structure by bonding with adhesive. Because the fixing jigs are detachable, the transducer can be demounted and set on a different structure. This allows this transducer to be used repeatedly on different structures. In addition, the small-size feature makes this transducer suitable for indoor measurement.
