Bearing Vibration Analyzer Bearing Vibration Measuring Instrument Deep Groove Ball Bearings Vibration Velocity Tester
Product Overview and Applications
The bearing vibration (velocity) measuring instrument is a specialized instrument for measuring the vibration velocity of deep groove ball bearings, angular contact bearings, tapered roller bearings, automotive water pump shaft bearings, and textile bearings. It consists of a velocity-type sensor, driver, sensor position adjustment device, pneumatic loader, and measuring amplifier. It is suitable for bearing manufacturers for bearing vibration testing, motor manufacturers and inspection departments for bearing acceptance testing, and also for universities and research institutions for bearing vibration analysis.
Performance Characteristics
1. The resonant frequency of the velocity-type sensor is above 12kHz.
2. High rotational accuracy of the hydrostatic spindle and low starting temperature.
3. Integrated circuit printed circuit board for easy maintenance.
4. Equipped with a preset value circuit for quick measurement.
5. Equipped with a loudspeaker for monitoring bearing noise.
6. Equipped with a calibration circuit for calibrating the measuring amplifier.
7. Stable and reliable radial and axial loading.
8. Simultaneous display of low, medium, and high frequency bands.
9. Output interfaces for low, medium, high, and broadband signals are available for connection with other instruments for further analysis of bearing vibration.
