Abstract
A vibration sensing device including a strip bearing a pattern of markings. The strip is caused to slide back and forth in front of a sensor as the result of vibration or displacement of an object to which either the strip or the sensor is attached. By varying the spacing between the markings on strip, the direction and approximate speed of the motion can be sensed by the frequency of the signal generated by movement of the pattern past the sensor and its rate of change. The vibration sensing device can be made to sense out of balance (OOB) or vibratory motion of a piece of equipment such as a washing machine, motor engine or other device during use or transport.
