Abstract
A stem load determining system comprises a method and apparatus for determining the load developed on a threaded stem, including a valve stem driven by a valve operator. An integral component of the apparatus is a stem strain transducer uniquely designed to girp a threaded stem to define a guage length on the threaded stem and to detect and measure deformation of the stem at the guage length when subjected to a compressive or tensile load.
