The linear pattern Karma 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. OMEGADYNE® 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. Karma gages are supplied with
plated solder pads for easy wiring.
To determine if the strain gages have
temperature characteristics matched to
steel or aluminum, see (on the Spec sheet) 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.
