Spark gap measuring and monitoring method and device, for providing, during operation, a signal indicative of the intended performance of the spark gap (1), in particular a spark plug of a combustion engine. The device includes an electrical detecting element which is coupled inductively to a connecting lead (4) of the spark gap (1), for example a toroidal coil (8), which detecting element is connected to a processing circuit (9-11) for the purpose of converting the electrical signal produced by the detecting element into a measuring signal indicative of the spark gap (1) performance, for example the spacing (d) between the electrodes (2, 3). Measurement results obtained from an initial measurement can be established as reference data by means of memory elements and circuit elements. The measuring signal is then analyzed by means of an analyzing circuit (14) as a function of the reference data.
Method for monitoring, during operation, the performance of an electrical spark gap, in particular a spark plug of a combustion engine, which is connected to a device for generating electrical high voltage, wherein current arising during the flashover of the spark gap being detecting is converted into a measuring signal representative of the instantaneous operational condition of the spark gap, and analyzed, including the following steps:
Device for monitoring, during operation, the performance of an electrical spark gap, in particular a spark plug of a combustion engine, which is connected to a device for generating electrical high voltage, comprising means for detecting current arising during flashover of the spark gap, said spark gap having spaced electrodes, an electrical processing circuit for converting the detected current into a measuring signal representative of an instantaneous operating condition of the spark gap and means for analyzing the measuring signal, including means for providing reference data representing the performance of the spark gap from an initial measurement, means for recording the reference data, and wherein the means for the analysis of the instantaneous measuring signal is designed for signalling discrepancies between the instantaneous measuring signal and the reference data.
