Unamplified flange models feature extended speed range and high overall performance accuracy. Only minimal maintenance is required due to the bearings-only contact design of the torque sensor. Unamplified shaft torque transducers are ideal for test installations running long-term durability testing; the non-contact nature of the signal transfer virtually eliminates the need for maintenance. The range of Specialty non-contact rotary torque sensors adaptable for use for special applications have been developed for include hydraulic pump testing, hydraulic motor testing, military aircraft test stands, aircraft starter testing, and cross-bleed starting.
