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

stress concentration or high gradient
areas. The terminations are offered both
at one end of the grid, or with one at each
end of the grid. Wide or narrow linear
grid patterns are available.
To determine if the strain gages have
temperature characteristics matched
to steel or aluminum, see the column
labeled “COMP” short for compensation,
“ST” indicates steel, “AL” indicates

aluminum. See the column labeled
“BTP” for accessory bondable terminal
pad model numbers.
Dimensions are listed for pattern gage
grid length (A) and width (B), and the
matrix or carrier length (C) and width
(D). The patterns include alignment
triangles and letter codes indicating
creep code.

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.
