Correcting revolution rate measurement value - restricting successive output value changes to defined values for roundness or vibration-dependent errors

摘要

Each revolution rate measurement is compared with the output of the preceding measurement. The measured value is delivered as the new output value when it is greater than or less the the preceding measurement value by less than a max. permissible increase or decrease value. Whenthe new value differs from the preceding value by greater thanthe max. permissible increase or decrease value, the new output value is generated by adding or substracting the max. permissible value to or from the old value. USE/ADVANTAGE - Correcting errors in revolution rate value of shaft with rotatable wts. measured at regular time vibration. Enables output signal to be used for the control parameter of a connected regulator, e.g. for shafts in motor vehicle engines or transmissions.
