Strain Gauge

A Strain Gauge is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of Strain Gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate.[1] As the object is deformed, the foil is deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.

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.

Some seldom, if ever, ordered patterns listed in previous versions of this databook have been omitted. We will, of course, continue to make these patterns available upon request for customers presently using them. For details, contact the Applications Engineering Department at the our office nearest you.

Separate listings are provided for special-use Strain Gauges and sensors:

• Residual stress

• Magnetic fields

• Weldable gages

• High temperature gages

• Manganin pressure gages

• Shear modulus gages

• Embedment gages

• Temperature sensors

• Crack detection sensors

• Crack propagation sensors

• Displacement sensors

Vishay Advanced Sensors Gauges

Customers whose application requires gages for the manufacture of precision commercial transducers are strongly encouraged to contact our Applications Engineering Department. They can provide assistance in the selection of the proper Advanced Sensor for your particular application.

Vishay Custom Strain Gauges

Micro-Measurements maintains the most extensive variety of catalog Strain Gauges available today. Whether for stress analysis, transducer manufacturing, or special-purpose applications, we have not only a wide selection, but also a large and varied inventory that is readily available for immediate delivery.

However, many of our customers have applications requiring gages that are manufactured to their individual specifications. While we believe our wide variety of standard catalog gages will satisfy most requirements, we recognize the need for custom products and are committed to serving it well.
