Implementation of Electronic Sensor for Assessment of Explosive Performance by Velocity of Detonation Measurement

Detonation velocity is an important property to consider when rating an explosive. It is an established fact that measuring velocity of detonation gives a good indication of the strength and hence the performance of the explosive. This paper presents and discusses the design and implementation of continuous wire discrete resistance VOD measuring technique (sensor)for bulk explosives. In this technique step change in resistance is preferred to increase the system reliability as well as it reduces the system complexity. Sensor used in discrete point´s method is based on resistance change in the region of several kilo ohms improving the noise immunity.
