Vibration analysis is a key tool in estimating the condition of a roller bearing. The slow change in the vibration spectrum provides indications of the remaining life of a bearing and can be used as a criterion for its replacement. The spectral distribution can deliver accurate information on the type and location of the damage.
PT 501 contains six interchangeable roller bearings on which different faults can be detected and explained. The radial load on the bearing is set within broad limits using the loading device.
An electric motor with variable speed via frequency converter is used as drive. An acceleration sensor with measuring amplifier serves to measure the vibrations at the bearing housing. The speed is measured with an optical sensor.
The measured values are transmitted directly to a PC via USB. The software for vibration analysis is included. The analysis software offers the following features: two-channel oscilloscope for investigations in the time range; two-channel spectrum analyser for investigations in the frequency range; vibration measuring unit; envelope analysis for bump effects and roller bearing damage.
