| 摘要 |
The present invention relates to measuring equipment (1) that includes at least two sensors (2, 3), each being adapted to sense a measurement magnitude, a measuring card (6) to which said sensors (2, 3) are coupled, and a computer unit to which the measuring card is coupled. At least one of the sensors (2) is adapted to sense prevailing frequencies of an object (11) to be measured. At least one of the sensors (3) is adapted to evaluate prevailing tacho-pulses of an object (11) to be measured. The circuits in said measuring card (16) are adapted to evaluate prevailing sound and vibrations generated by the rotating object (11) in response to information received with respect to prevailing frequency and prevailing tacho-pulses, by dividing the time distance between two tacho-pulses into a number of sub-sections and generating a circuit-internal tacho-signal for each sub-section. |
