摘要:
A method of and arrangement for the production of a control signal for automatically operated devices, wherein the control signal is derived from a digital value to be measured repeatedly, which comprises the steps of forming the individual difference signals between an actual measured digital value and a reference value of each individual measurement, and storing the individual difference signals. The individual difference signals are each compared with settable limit values representing statistical variations of the measured value and representing erroneous measurements and material faults of the goods to be measured. A control signal is emitted upon surpassing of the limit value for the statistical variation by an individual difference signal, to a regulating unit control of the control device, and the individual difference signals are cancelled and the emittance of a control signal suppressed upon surpassing another limit value repressing the erroneous measurements and material faults.
