Error Corrections: Strain Measurement Errors

Error Corrections

It should be obvious that to obtain consistently accurate strain data, one must be familiar with all the potential error sources at each stage of the measurement process. Judgment is required to ascertain which -- if any -- errors may be of significant magnitude in any particular measurement. Additionally, it is necessary to "design" the measurement system to suit the situation. This involves selecting components, establishing procedures, incorporating corrections, etc., to eliminate or minimize the errors to an acceptable level of uncertainty in the measurement data.

The obvious route to minimizing uncertainty in strain gage measurements is the attainment of knowledge and skills in the use of gages. Much of this knowledge is incorporated into the software supplied with our System 5000 and System 6000 Stress Analysis Data Systems.

Beyond the above, the strain gage user has, by telephone, facsimile, and email, instant access to the expertise of the Vishay Measurements Group Applications Engineering Department . The Applications Engineering staff has many years of experience with strain gages, and has counseled gage users on virtually every imaginable type of installation. They are readily available to assist you with your efforts in controlling errors in strain measurement.
