High-Temperature Patterns Vishay Micro-Measurements Special Purpose Strain Gages - High-Temperature Patterns FEATURES * Measurement range to 2100F (1150C) * Free-filament Kanthal alloy grids for bonding with ceramic adhesives. * Linear and Tee rosette patterns ZC-Series strain gages are etched Kanthal (Fe-Cr-Al alloy) foil grids in free-filament form for high-temperature applications. They are bonded with either ceramic adhesives, or by the use of flame spray or Rokide (R) processes. ZC-Series strain gages cannot be self-temperature compensated, and a dummy compensating gage must be GAGE PATTERN Actual size shown. Enlarged when necessary for definition. inch millimeter G1262 GAGE DESIGNATION RES. IN OHMS OPTIONS AVAILABLE Linear pattern. 2X GAGE LENGTH used for minimizing of thermally induced apparent strain (thermal output). Several patterns are available with built-in compensating grids. ZC-Series strain gages are supplied with a removable hightemperature carrier for gage handling during installation. All patterns have 1in (25.4mm) Nichrome ribbon leads spot welded to the gage tabs for leadwire attachment. 1X OVERALL LENGTH GRID WIDTH OVERALL WIDTH 0.062 0.150 0.076 0.076 1.57 3.81 1.93 1.93 MATRIX SIZE ZC-NC-G1262-120 N/A G1263 120 Linear pattern. 2X 1X GAGE LENGTH OVERALL LENGTH GRID WIDTH OVERALL WIDTH 0.100 0.248 0.179 0.179 2.54 6.30 4.55 4.55 MATRIX SIZE Document Number: 11532 Revision 17-Feb-03 N/A ZC-NC-G1263-120 micro-measurements@vishay.com 120 www.vishaymg.com 1 High-Temperature Patterns Vishay Micro-Measurements Special Purpose Strain Gages - High Temperature Patterns GAGE PATTERN Actual size shown.
