Abstract (en)

[origin: EP0285822A2] The measuring device for determining the operating efficiency of a machine, which receives the operating noises by means of a microphone (16), has an electronic evaluation circuit (20) with a microprocessor, in which individual values of the operating time, the stoppage times, the pauses, the number of operating interruptions and/or the interruption duration are evaluated from the microphone signals in conjunction with a timing generator (28) in a plurality of register stores (23 - 26) and are displayed in an indicator, and in which the instantaneous operating efficiency of a machine is calculated and indicated, especially continuously. <IMAGE>
