KM Series
Embedded Strain Gages

  • RoHS

Summary

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.

Contents

When ordering, please suffix the lead-wire cable code to the model number with a space in between.

e.g.
KM-120-120-H2-11 suffixes W5M3 for the gage with a 5 m long vinyl-coated flat 3-wire cable becomes
KM-120-120-H2-11 W5M3
