Explained: The Strain Gauge Excitation Voltage

Compliance with a strain gauge's maximum permissible bridge excitation voltage is essential to avoid measurement errors. Read this white paper to learn what the significance of this value is and how it is calculated.

Temperature compensation for strain gauges - Theory and practical implementation

Each strain gauge produces a temperature-dependent measurement signal. Read in this article how the temperature-dependent apparent strain can be reduced by temperature response matching.

The industrial benefits of utilizing well-proven strain gauges

Well-proven foil-type strain gauges have many advantages over alternative technologies believes HBM's Dr.-Ing. André Schäfer

Successfully compensating for lead resistances

If measuring points are not directly accessible, the measuring instruments need to be connected using long cables. The disadvantage: The lead resistance can negatively affect the measurement. Various types of strain gauge...

Installing strain gauges on fiber-reinforced composites

Fiber-reinforced composites are used in an increasing number of applications. These materials too can be tested using strain gauges, which is shown in this article.

Selection and overview of covering materials

It is essential to properly protect a strain gauge measuring point from environmental influences. This article provides you with the information you need to find the right covering agent to ensure protection of your measuring...

Improving strain measurements - You need real-world tests to complement finite-element analysis

Most electronics engineers don't give much thought to strain measurements—EEs are usually more concerned with electrical reliability than with structural integrity. But for engineers who develop products such as aerospace...

Structural integration of strain gauges

Strain gauges can be integrated directly into a structure instead of being installed on the surface of a material. Read our extensive instructions on the topic to learn how to successfully integrate strain gauges into structures.

Using statistical techniques to validate field test data for fatigue analysis

This paper describes some statistical techniques for taking measured data and projecting what the expected time history and resulting fatigue damage would be if test data were collected for much longer times.

Strain gage ¼ bridge calibration with shunt signals

In the field of Experimental Stress Analysis hundreds and sometimes thousands of single strain gages are to be measured. Calibration of such big systems can be a tedious task.

High-precision measuring technique for strain-gage transducers

The signals of strain gage transducers are very small. In consequence, error signals can even exceed the measuring signal amplitudes and therefore must be suppressed by sophisticated measuring circuits.

Linearity and Sensitivity Error in the Use of Single Strain Gages with Voltage-Fed and Current-Fed Circuits

An important part of experimental stress analysis is the measurement of strain with single strain gages and the type of circuitry employed influences the linearity and sensitivity of the measurements.
