Prompt Time Measurement of Semi - conductor Electric Detonator

摘要

This paper introduces adopting sonic transducer and ionization target transducer to measure ignition delay time of some batch of electric detonators. And introduces the acquisition of time switching signal and the influence of the selection of transducer to the measuring results, When adopting ionization target transducer, the semi-conductor initiation delay time is about 750 μs, grading is about 200 μs.
