DY Strain Gauges with 2 Parallel Measuring Grids for Measurements on Bending Beams

DY strain gauges have two measuring grids arranged parallel to each other. Typical applications for these strain gauges (SGs) include measurements on bending beams. Further information on this topic is available in our brochure "Use of the Wheatstone Bridge Circuit" and in our specialist publication "An Introduction to Measurements Using Strain Gauges"

Double strain gauge DY1 and DY4 are available with a nominal (rated) resistance of 350 ohms in various geometries, with temperature responses adapted for steel, aluminum or to customer specification.

The measuring grid consists of constantan; the material of the measuring grid carrier is polyimide.

The following temperature matching codes (1 … 9) apply to all types

1 = Ferritic steel (10.8 ppm/K; 6.0 ppm/°F)
3 = Aluminum (23 ppm/K; 12.8 ppm/°F)
5 = Austenitic steel (16 ppm/K, 8.9 ppm/°F)
6 = Silica/composite (0,5 ppm/K; 0.3 ppm/°F)
7 = Titanium and gray cast iron (9 ppm/K; 5.0 ppm/°F)
8 = Plastic (65 ppm/K; 36.1 ppm/°F)
9 = Molybdenum (5.4 ppm/K; 3.0 ppm/°F)

Remarks on Y Series

1) Strain gages are available in various temperature matches.
Insert the code in place of the placeholder “” to get the ordering number of the strain gage you need

2) Only available in matches for aluminum, ferritic and austenitic steel

3) Maximum permissible effective supply voltage (specified for steel)

4) Preferred types (available from stock) with the temperature matches specified in the column

5) With application aid (cut-to-size polyimide adhesive strip for easy positioning)
