Color code of gauge base for different test specimen

TML strain gauges are almost self-temperature compensated. Series F, UF, CF and WF are self-temperature compensated for the most commonly found material mild steel, stainless steel/copper alloy and aluminium, and are identified with gauge base colors of red, brown and green respectively.

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.
