摘要

This paper compare the different methods of rolling/ball bearings condition monitoring and describes a resonance method and universal single sensor allows measuring vibration in a range of 2 Hz to 20 kHz, bearing health based on shock pulse (resonance) method and temperature in a range of-40 C to +120 C. The sensor design based on flex piezoelectric technology and has integrated electronics. The connection with DIN rail transmitter is realized by current line drive which provided low sensitivity to electrical hazards and possible long cable length without signal loss at high frequencies. It is specially designed to provide early warning of absolute vibration level as well as typical ball/rolling element bearing faults such as cracked races, spalling, brinelling, and looseness. It has six modes (outputs) of detection that are working simultaneously. The options include RMS velocity, true PK acceleration, AC acceleration, temperature, bearing condition and lubrication condition. The diagrams of the channel and test results are discussed.
