SYSTEM TO DIAGNOSE TECHNICAL CONDITION OF SHAFT OR SHAFTING OF ROTOR MACHINE USING CONTACT SENSORS OF ABSOLUTE VIBRATION Russian patent published in 2014 - IPC G01H11/00 

FIELD: measurement equipment.

SUBSTANCE: system to diagnose technical condition of a controlled shaft or shafting includes two contact sensors of absolute vibration fixed on the shaft and at least one device to match signals of the specified sensors connected to a reading device. At the same time devices of signal matching and the reading device in the form of a common measurement block are fixed on the shaft of the rotor, sensors are installed in the plane of measurements perpendicularly to the diametrical axis of the cross section of the shaft, and the reading device of the measurement block is equipped with a port of a flash card of digital memory for automatic recording of measurement results on it. The system also comprises a separate hardware-software block equipped with a similar port for detailed processing of measurement results in accordance with a specification for diagnostics. The number of sensors in the plane of measurements shall preferably be even, and each sensor at the same shall pair with another similar sensor, arranged on the same diametrical axis at the opposite side of shaft.

EFFECT: increased accuracy of measurements and increased reliability of information processing.
