The linear pattern strain gages are used to measure strain in a single direction. The strain gage pattern is shown on the left side of the table. Notice the “arrow” which indicates the principal stress direction.

The linear pattern strain gages are available in a variety of styles and sizes. OMEGA® offers miniature linear patterns for strain measurement of a

STRAIN GAGES

BONDABLE TERMINAL PADS

When installing strain gages with ribbon leads or Solder Pads, use Bondable Terminal Pads (BTP) between the strain gage and the wires to your instrumentation.

The Bondable Terminal Pads provide a large easy to use soldering area and provide strain relief between the strain gage and the heavy instrument wires.

Using Bondable Terminal Pads is simple. Use the same adhesive and bonding procedure on the Bondable Terminal Pads as you use on the strain gage.

OMEGA offers BTPs in several sizes and wiring configurations to fit most all strain gage applications.
