Linear pattern precision strain gauges with
minature and medium length grids
are for general purpose and stress
analysis applications. Available
with either two 1-meter leads or
three 3-meter leads and 120 Ω or
350 Ω resistance. All models are
compensated for steel.
The planar XY pattern (0 / 90°) allows
precision strain measurement by
eliminating the errors often
associated with a stacked XY
pattern. These strain gauges are available
with either two 1-meter leads or
three 3-meter leads per grid and
are compensated for steel.
The planar rosette pattern (0 / 45°/ 90°) allows
precision strain measurement
by eliminating the errors often
associated with a stacked pattern.
These strain gauges are available with
either two 1-meter leads or three
3-meter leads per grid and are
compensated for steel.
