Since its founding in 1987, Advanced Telemetrics has been in the business of solving unique rotating sensor measurements. The company specializes in rotating telemetry systems, which are used to couple data from rotating shafts or machinery to a stationary recorder. ATi products have been used extensively for powertrain testing in automotive, aerospace and a variety of other research and development related applications. ATi transmitters are crystal-based and do not require tuning. The crystalled operation also permits multiple channels to be used concurrently, with no crosstalk. The RF output signal from the transmitters is relatively powerful, which makes the system very immune to electrical interference. Since the transmitters are potted in high-strength epoxy, they are capable of operating in extremely hostile environments with excessive vibration and heat.
