KC Type:
Featuring a longer gage length, the KC 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.
KM Type:
The KM series gages are designed to be embedded in mortar or
concrete for the purpose of measuring the internal stress.
To ensure better adhesion to mortar or the like, the KM series gages
feature a specially treated surface.
They also provide suitable waterproofness and elastic modulus for
the intended purpose.
KMC Type:
The KMC series gages are designed to measure self-shrinkage and
self-stress of cemented materials. 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.
