Although scheduled maintenance or corrective maintenance are common in the FA industry, predictive maintenance has recently been attracting attention. Predictive maintenance involves making use of various sensor information to predict when trouble might occur and then implement preventive measures. This can help to prevent downtime loss caused by unexpected equipment stoppage. Another benefit is that this does not require keeping excess repair parts on hand, as maintenance periods would be known in advance.
At only 5.0 x 5.0 x 3.5 mm in size, this product can be retrofit to mechanical component parts as a sensor node. It can also be embedded guides or bearings. It includes a temperature sensor to detect abnormal heat generated by equipment. It incorporates piezoelectric PZT ceramic vibration detector element technology developed by Murata over many years, allowing it to measure the vibration acceleration (up to 11 kHz) of high-frequency components where metals rub together without influence of noise. For rotary bearings, FFT analysis1 can be used on vibration data for areas where grease has worn away or small surface scratches to detect abnormalities, and predict when trouble might occur sooner.
