Rpm & Speed          Rotational detection from sound & vibration

B-1-1       Measuring the rotational speed of a pump from sound (noise)

  • This example shows how to measure the rotational speed of built-in pump and similar equipments. The rotational speed of pump can be measured by capturing the exhaust sound with microphone, and performing frequency calculation in the periodic change of sound pressure even though the rotating shaft is not come out.
  • Two staged, upper- / lower-limit comparator output function is provided as standard which is useful to make OK, LOWER, or UPPER decision in production line use.
  • Enable to control data management by RS-232C
