Description

Micro-Measurements has been dedicated to the development, manufacture, and marketing of products for high-precision strain and stress measurement since 1962. For purposes of experimental stress analysis—whether preproduction prototype evaluation, field-service testing, failure analysis, or pure research—we offer a full complement of the sensors, instrumentation, and installation accessories necessary to obtain accurate, reliable strain and stress data. Micro-Measurements strain gages (strain gauges) and accessories also fulfill manufacturers’ requirements for a wide variety of transducers for measuring physical variables (weight, force, torque, pressure, etc.)

 

  • General Information

    General-use Micro-Measurements strain gages are listed in groups according to grid geometry:

     

    For each of these grid geometries, those patterns most commonly used by our customers are listed first with complete specifications. Additional listings with partial specifications follow for the less commonly used patterns. In both listings, the gage patterns appear in alpha-numeric order, increasing from the shortest grid lengths to the longest.

  • Strain Gage Dimensions

    Gage length is an important consideration in strain gage selection, and is usually the first parameter to be defined. Dimensions listed for gage length (as measured inside the grid endloops) and grid width refer to active grid dimensions. Overall length and width refer to the actual foil pattern, not including alignment marks or backing. The matrix size represents the approximate dimensions of the backing/matrix of the gage as shipped. Matrix dimensions are nominal, with a usual tolerance of ±0.015 in (±0.4 mm). If the gages are encapsulated, the matrix may be smaller by as much as 0.01 in (0.25 mm). Most patterns also include trim marks, and, for use in a restricted area, the backing/matrix may be field-trimmed on all sides to within 0.01 in (0.25 mm) of the foil pattern without affecting gage performance.
