Strain Gauge

Strain gauge testing is a reliable and accurate method of testing the structural integrity of the equipment. This type of test measures the amount of stress and strain that equipment is subjected to during various environmental and operational conditions. By placing strain gages, which are resistive devices, at key points on the equipment, the amount of stress can be measured and compared to the design’s allowable limits. 

This type of testing is specified in various standards, such as UL-427, UL-698, and UL-471. This testing is important to ensure that the equipment is able to function as intended and to protect operators and maintenance personnel from any potential risks associated with the equipment. The strain gauge testing process is a valuable tool to identify weak points in equipment, as well as to monitor the effects of changes in temperature and operating conditions. The results of this testing can be used to accurately determine the life cycle of the equipment and to identify any potential problems that may arise.
