Stress, Strain, and Strain Gages, Page 3 Strain gage electronics Since R/R is very small and difficult to measure directly, electronic circuits must be designed to measure the change in resistance rather than the resistance itself. Fortunately, there are circuits available to do just that. Most strain gauges are smaller than a postage stamp, and they look something like this: A strain gauge’s conductors are very thin: if made of round wire, about 1/ inch in diameter. Alternatively, strain gauge conductors may be thin strips of the metallic film deposited on a nonconducting substrate material called the carrier. The latter.

Strain gauge amplifier (RS stock no. ) and printed circuit board (RS stock no. ) Description and operation The strain gauge amplifier is a purpose designed hybrid, low noise, low drift, linear dc . Introduction to Strain Gauges and their usage Strain Gauge Applications Strain gauges are used to determine or verify component or structure stresses, or by manufacturers of load cells, pressure and torque transducers, etc., where they utilise the physical parameter being measured to strain a part of the transducer in a linear way. Errors Due to Shared Leadwires in Parallel Strain Gage Circuits A fundamental problem with the use of a common leadwire is that all data are vulnerable to degradation or even to complete loss should a single gage (or grid) malfunction. These malfunctions can range from a short circuit within a gage, to a low resistance to ground, to an open. Bridge Measuring Circuits in the Strain Gauge Sensor Configuration 77 a) b) Fig. 1 The wire before (a) and after force application (b) F A (1) With the applied force, the wire length increases (L), the cross-sectional area decreases (Fig. 1), and the deformation that occurs, defines axial strain. Strain Gages Structure of Strain Gages There are many types of strain gages. Among them, a universal strain gage has a structure such that a grid-shaped sensing element of thin metallic resistive foil (3 to 6µm thick) is put on a base of thin plastic film (15 to 16 µm thick) and is laminated with a thin film. Laminate film Metallic resistive foil.
