Color coding for specimens

Most of TML strain gauges are self-temperature compensated for test specimens with a specific thermal expansion coefficient. The F, UF, CF and WF gauge series are color coded as indicated below. The suffix -11, -17 or -23 of type name indicates the thermal expansion coefficient of objective specimen material.

Specimen material Thermal expansion Color of backing Example of type name
Mild steel 11×10-6/°C Red FLA-3-11
Stainless steel
Copper alloy
17×10-6/°C Brown FLA-3-17
Aluminum 23×10-6/°C Green FLA-3-23
Name of each part
Dimensions are indicated in the specification of each gauge. Each gauge pattern indicated in respective column is not in an actual size.
