摘要
The starting point is a known method for determining the signal-to-noise margin of an electronic ignition device, the electronic ignition device having trigger electronics (11), a charge and an ignition wire (12), an ignition wire (12) being applied via the trigger electronics (11), with which the cargo is detonated. The steps are: - expansion of the charge from the electronic ignition means while obtaining a disarmed ignition means (10), - thermal and mechanical coupling of an optical sensor crystal (20) to the ignition wire (12) of the disarmed ignition means (10), the optical sensor crystal ( 20), depending on the temperature, reflects light rays more or less with regard to their wavelength, - further instrumentation. With the new method, realistic values of the noise margin should be determined. To do this, surround the ignition wire (12) and the optical sensor crystal (20) with paraffin oil (50) before carrying out the EMC tests. The paraffin oil (50) simulates the charge that surrounds the sensor crystal in a sharp assembly position.
