In this video, Darryl discusses how temperature can impact your strain gage measurements and what are the available solutions such as choosing the right Self-Temperature Compensation (S-T-C).
What is the STC number in the gage part number?
STC stands for Self-Temperature-Compensation. The number itself relates to the material coefficient of thermal expansion (CTE) that the gage is intended to be used on. For example, STC 06 is for low-carbon steel, which has a CTE of approximately 6.7 ppm/°F (12 ppm/°C). Self-Temperature-Compensation is a technique used when manufacturing the foil strain gage sensor to provide a gage response that minimizes the free expansion of a test part subjected to a change in temperature. You can learn more about STC by reading Tech Note TN-504 .
Self-temperature-compensated strain gages are designed to produce minimum thermal output (temperature induced apparent strain) over the temperature range from about –50° to +400°F (–45° to +200°C).
Consideration for STC are:
1. Test specimen material
2. Operating temperature range
3. Accuracy required
