The AT-4500 EasyApp from Accumetrics Associates provides wireless, high-bandwidth rotating shaft torque measurements without batteries. The system connects to a shaft-mounted strain gauge bridge and transmits electromagnetic interface-resistant 16-bit resolution data continuously at 26484 samples/s. Analog voltage of 2 kHz bandwidth is output, and remote transmitter shunt calibration is controlled at the receiver. The AT-4500 eliminates the need to install in-line torque transducers, mechanical slip rings, or telemetry collars machined for a specific shaft diameter. Using different length Kevlar straps, the transmitter can be mounted on various shaft diameters and can be used at over 9200 rpm on a 3-in (76.2-mm) shaft. Balance is maintained by the counterweight/strap tightening yokes. The transmitter packaging seals against mud, ice, rain, and other environments, making it suitable for long off-highway vehicle tests.
