Apparatus and method for measuring an explosively generated overpressure

A method of detecting an explosion comprises detecting ionisation. Ionisation detection means 12 (optionally an ionisation pin) are located remotely to an explosive source 11 and at least a first explosively generated ionisation event 17 is detected using the ionisation detector, following detonatio...

Zusammenfassung:	A method of detecting an explosion comprises detecting ionisation. Ionisation detection means 12 (optionally an ionisation pin) are located remotely to an explosive source 11 and at least a first explosively generated ionisation event 17 is detected using the ionisation detector, following detonation of the explosive source 11. The ionisation detection means may comprise an array of ionisation pins to detect propagation of the event. The pins may comprise a core and outer sheath (Fig 5). Particularly suited to very near-field overpressure measurement applications. Further pressure sensors may be included with the ionisation detectors.
