Torsional Vibration Monitoring Systems

ATi’s Torsional Vibration Monitoring System transmits torsional acceleration from a rotating shaft or component, while the machinery is running. The system consists of a transmitter and two accelerometers housed in a rotating collar along with the stationary receiver.

The accelerometers are mounted 180 degrees apart with the output processed, such that gravitational effects are cancelled. This proprietary circuitry permits extremely high sensitivity measurements. The conditioned signal is then transmitted to the receiver.

In addition to a display, the receiver also has analog outputs, which can be monitored or recorded for analysis. Each system comes complete with all required accessories including: antennas, AC power adapter or DC power cord for Receiver, and all required cables.

ATi's Torsional Vibration Monitoring Systems are use for Noise Vibration and Harshness (NVH) testing and analysis in automotive drivetrain, wind turbine gearbox and various other applications where measuring or monitoring rotating vibration is important.
