ATi’s Dynamic Torque Sensing Systems are utilized in applications where conventional rotary torque transducers are not practical due to excessive shaft speeds, vibration, and dirty, oily environments. These factors pose major problems for conventional foot-mounted rotary torque transducers’ bearings and slip rings.
Extreme sensitivity. A second dynamic output is available, which can be set for a full range as low as 1% of the primary output. Thus, output resolution can be as low as 0.0025% of the full primary output range. The secondary dynamic output would also have an overload capability of 500:1. This makes the sensor extremely useful for measuring gear mesh torsional data or extremely small torque fluctuations. This is possible since the data is not corrupted by bearing noise from the sensor.
Highly reliable and durable. RF Telemetry is used for data transfer while Induction Power is used for power transfer to the rotating sensor. These technologies permit excessive movement between the rotating sensor and stationary loop antenna with no effect on the signal quality – minimal alignment between the stationary and rotating components is required.
Immune to the Environment. The RF Telemetry and Induction Power are also immune to dust and oil build-up.
