To Ensure Safe Usage

TPH-A series torque transducers are not cased, and thus, the rotating part and couplings are exposed.
Considering fatigue failures of these parts, the user should consider installation of a safety steel cover, etc.
Specially designed diaphragm couplings are incorporated into all transducers. The instruction manual describes the maximum safe misalignment from the shaft. For stable torque measurement, set the couplings to minimize misalignment.
