Abstract
A method for measuring vibrations in which gravity forces and acceleration forces resulting from machine vibrations are measured using an accelerometer/inclinometer sensor coupled to a non-rotating part of a rotating machine, the orientation of the sensor with regard to the direction of action of the gravity forces is determined from a stationary component of sensor output, and non-stationary components of sensor output are evaluated based upon the determined sensor orientation. Both the result of the alignment process and also the result of the vibration measurement are communicated to the user as an easily understandable characteristic on a display of an evaluation unit.
