Abstract

With the increasing demand for industrial automation and intelligence, shaft power measurement technology, as a key parameter detection method in fields such as ships and wind power, is gradually developing towards high precision and non-contact direction. This article is based on strain gauges, electromagnetic sensing, and wireless communication technology, and designs and develops a non-contact shaft power measuring instrument. Combining experimental verification and theoretical analysis, the measurement principles of speed, torque, and thrust are discussed, and the measurement errors are analyzed in detail, providing a basis for the widespread application of shaft power meters.

Keywords
