Founded in 1992, Accumetrics designs, assembles, and supports wireless digital telemetry systems that transmit sensor data from rotating structures. The company is especially known for pioneering rotor ground-fault detection, while its systems also capture measurements from high-speed shafts in demanding industrial and power-generation settings. Accumetrics became part of PCB Piezotronics in 2013 and is now a wholly owned subsidiary of PCB Piezotronics and Amphenol Corporation.
