摘要： PROBLEM TO BE SOLVED: To provide a vibration measurement method of a sensor, which accurately measures a vibration generated in the sensor by using a vibration detector.
SOLUTION: In the vibration measurement method, the vibration detector 100 is ±1 wt.% of the weight of a gas sensor 1 or less, and attached to the gas sensor 1. Since a shift of an acceleration G due to the weight of the vibration detector 100 and a shift of a resonance frequency are suppressed to the minimum when the gas sensor 1 is vibrated, the vibration of the gas sensor 1 is accurately measured. Since a compact vibration detector having the weight less than ±1.0 wt.% is used, it is attached even in a narrow space such as an exhaust pipe of an automobile so as to provide a margin. The vibration detector 100 is attached to a position corresponding to a grommet 75 on an outer circumference of an outer cylinder 30. A vibration state of the gas sensor 1 including an effect due to the rigidity of the exhaust pipe is accurately measured thereby.
