The bearing signals are extracted by PCB 608A11 piezoelectric ICP Accelerometers attached over the bearing case and a NI cDAQ-9234 data acquisition system. Provision of NI Lab VIEW software with the DAQ facilitates in data acquisition. The vibration signal is collected after every 10 minutes of operation with a sampling rate of 25.6 kHz and signal length of 2560 (corresponding to 0.1 sec). The failure time for bearing B1 which is considered for further investigation is recorded to be12250 minutes in test one and that of the bearing B2 is 14990 minutes in test two.
