STC Explained
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.
