Prerequisites
- Mount the sensor on a stud or magnet and on a clean, very flat surface with no paint, if possible. Paint absorbs vibration and affects the data accuracy. Due to the short duration of bearing impacts, a higher frequency sensor with the Fmax set between 10,000 and 15,000 Hz works best, even if you measure slow speed machines.
- Place the sensor in the radial (horizontal) or axial position as close to the bearing load zone as possible.
- Set up a sensor.
Overview
Bearing/Gear Analysis - PeakVue detects anti-friction bearing or gear defects earlier than normal vibration measurements. It also detects bearing defects on extremely slow turning shafts that do not generate enough vibration to detect with normal measurements. See PeakVue and demodulation for more information on PeakVue technology measurements.
If you collected data on the measurement point, Bearing/Gear Analysis - PeakVue starts with the original acquisition settings and adds the PeakVue processing. You can also set a lower Fmax for the PeakVue measurement if the original spectrum shows no vibration peaks past a certain frequency. Mark the cursor to the right of the last vibration peak and select Bearing/Gear Analysis - PeakVue. The Fmax of the new spectrum is lowered to the next available Fmax setting in the analyzer, above the marked frequency.
