摘要:
A rotating machine element is monitored for displacements using co-rotating sensors for acceleration, rotation or the direction of gravitation. In doing so, the sensor data are received by a, likewise, co-rotating electronic unit. The data can also be stored and further processed in this electronic unit.
摘要:
An alignment device with one or two optoelectronic transmitting and/or receiving units and an evaluation unit. At least one optoelectronic transmitting and/or receiving unit contains an inclinometer. Furthermore, the transmitting and/or receiving unit is connected to a vibration sensor which can be the inclinometer. 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 the evaluation unit. For vibration measurement at a non-rotating part of a machine, an accelerometer/inclinometer sensor may be used for measuring acceleration forces resulting from machine vibrations to be measured and for measuring gravity and an electronic evaluation unit determining the orientation of the sensor with regard to gravity from a stationary component of the sensor output and determining sensor orientation from evaluation of non-stationary components of sensor output.
摘要:
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.
