tion Torque, (shaft and flange type) transducers are
designed for installation between test pieces such as motors, switches, axles or shafts and
their mounting plate. These models operate and are calibrated in both directions. Stainless
steel construction enhances durability in harsh, industrial environments. These models have
no moving parts and utilize four bonded strain gages on a special machined portion of the
transducer to achieve a maximum non-linearity of 0.1% over a wide dynamic range. Typical
applications include tire braking, motor dynamometers, friction-skid testing, torque tables and
twist measurement.
