    gauge, developed at the NASA GRC for high temperature strain measurement applications, is stable to °C, but has a TCR of ppm/°C and an apparent strain sensitivity (δεa/δT) of +85 µε/°C, requiring temperature compensation for high temperature static strain measurements (refs. 2 and 6). Currently, this. DIN: Deutsches Institut fur Normung E.V. AWS: American Welding Society, Inc. IPC: Association Connecting Electronics Industries.

    Abstract The structural thermal test of an advanced ramjet missile section required strain measurements as high as K ( F). Since there is relatively little experience in the use of strain gages above the K ( F) level, a program was initiated to select and evaluate the best available gage. bonded wire strain gage makes it the best choice for dynamic, impact or vibratory strain measurements to °F (°C). While designed primarily for dynamic measurement applications, the active dummy method of temperature compensation can be used when static strain measurements are made. High-temperature weldable strain gages are available with.

    strain gage alloys, it does exhibit small changes in gage factor during high elongation. Without treating this subject in detail, it can be shown in theory that the gage factor of the strain gage approaches a value of 2+ ε when the gage alloy is strained beyond its elas-tic range. The elastic range for constantan is approximately %.File Size: KB.   Temperature adversely impacts strain measurements in many ways, though three are of primary concern: • The device or object studied will almost always have a non-zero coefficient of thermal expansion. Unless compensated for, changes in temperature will cause the item to which the strain gauge is attached to expand or contract, which is then indicated.
