Reinforcing Bar Meter
A Reinforcing Bar Meter (or Strain Meter) is a specialized sensor, often a strain gauge, welded onto steel rebar to measure stress, strain, and temperature changes in concrete structures, providing crucial data for monitoring structural health, especially in large projects like bridges or dams, allowing engineers to understand forces like thermal stress and long-term load effects.
The meter (strain gauge) is permanently welded to the reinforcing bar (rebar) before the concrete is poured which becomes part of the structural reinforcement, embedded within the concrete. As the concrete expands, contracts, or bears load, it deforms the rebar, which the strain gauge detects, converting these physical changes into electrical signals that represent stress and strain. There are many modern meters which include built-in sensors to simultaneously measure temperature, helping to differentiate thermal stress from other applied loads.
KSAT-A Reinforcing Bar Meter　300 N/mm2
The KSAT-A are used to measure stress applied to structural reinforcing bars, and are normally welded at both ends to form part of the reinforcement arrangement. And the meters are with built-in temperature sensor, making possible simultaneous measurement of stress and temperature.
