Linear Expansion Coefficient Measurement Strain Gauge

CTE Series Linear Expansion Coefficient Measurement Strain Gauge

This is the CTE series of strain gauge for measuring the coefficient of linear expansion. These strain gauges are designed to measure the coefficient of linear expansion of metals, plastics and substrates.
To make it easy to calculate the linear expansion coefficient of any material, the temperature-compensated material of the strain gauge is adjusted to 0×10-6/℃. The strain gauge enables the linear expansion coefficient of the measured material to be calculated using a simple formula.
In addition, the actual amount of deformation (strain due to external force + thermal strain) and total elongation can be measured in measurements such as electronic board measurements.
