Pre-Wired Strain Gauges for Easy Installation KFH KFH
  • Pre-Wired Gages Make Installations Easy!
  • No Soldering at the Measuring Point
  • Sold in Packs of Ten
  • Each Gage has 50 mm of PTFE Cable before Transitioning to AWG 28 Leads to Prevent Leads from Adhering During Installation
  • Rugged Polyimide Carrier
  • Fully Encapsulated Gages for Protection from the Environment
  • Sold in Packs of 10


Linear pattern precision pre wired gages 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 gages 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 gages are available with either two 1-meter leads or three 3-meter leads per grid and are compensated for steel.
