发明名称 PREVENTING AN OVERLOADING OF THE ELECTRONIC EVALUATION SYSTEM DUE TO VOLTAGE SPIKES IN MAGNETO-INDUCTIVE FLOWMETERS
摘要 The disclosure relates to a circuit arrangement for preventing overloading of magneto-inductive flowmeters. The disclosure can protect the amplifiers which are connected downstream thereof or the electronic evaluation system from overloading. To this end, the signal input circuit is provided with additional voltage-limiting diodes disposed downstream of the impedance converters so that eventual voltage tips are prevented during modulation in the downstream amplifiers of the evaluation electronics.
