Operation of a handpiece is sensed, such as by detecting temperature and/or vibration associated with one or more of the bearing rings supporting the turbine in the handpiece. When operation exceeds a threshold, a visual or audible indication is provided, and power to the turbine may be interrupted. The sensor(s) may be built into the handpiece, or be part of a removable girdle placed on the handpiece. Typically, the handpiece is used for dental or medical applications. |
