The STS Series is our general purpose reaction type shaft torque sensor. They are often installed between devices such as motors, switches, shafts or axles, and their mounting plate to provide bi-directional torque output. They are available in six capacity ranges from 600 inch lbs. through 12,000 inch lbs., and are made from 17-4PH heat treated stainless steel. The sensing element incorporates bonded foil strain gauges of the highest quality and are sealed for protection against most industrial environments.
