ATi’s Half Shaft Telemetry System transmits torque signals from rotating shafts to a stationary telemetry receiver. It connects directly to strain gages adhered to the shaft, converting it into a torque sensor, allowing it to transmit shaft torque while the vehicle is operating. This system is a testing tool used by automotive and racing engineers to obtain real-time torque measurements from vehicle drivelines. The system can be installed on most any size shaft and is completely field installable by the user.
The collar, made from two-piece fiberglass composites, has no mechanical parts to wear out as found in slip rings, making it lightweight and maintenance free. It requires only 0.50” clearance, allowing the collar to be placed almost anywhere on the shaft.
Power is supplied to the Telemetry Collar inductively through a stationary loop adapter for continuous, uninterrupted operation. The receiver features an integral induction power supply, built-in speaker and a digital backlit LCD display which can be scaled to read out in Engineering units. The receiver can be powered directly from 12 VDC or with a 110/220 VAC 50/60Hz adapter and provides an analog output signal representative of the measurement for use in almost any data acquisition system.
The ATi Half Shaft Collar is now available with an optional RPM measurement option. The optical RPM sensor outputs 12 conditioned pulses per revolution.
