Quality & Process Control



Founded in 1985, OROS is a pioneer in noise and vibration analysis solutions.
OROS’s hardware & software are ISO 9001:2015 certified. Whatever the machine type (high speed turbine, compressor, transmission or a slow speed engine), OROS analyzers provide all the tools for rotating analysis from R&D, acceptance tests to diagnostics. OROS 3-Series analyzers feature flexible and accurate shaft speed measurement tools. Tachometer signals are over-sampled to ensure accurate rotating speed and phase. Signals can be adjusted for better pulse detection using filters, holdoff and hysteresis.
