Abstract

A constant current pulser, with adjustable pulse width and current, is designed to evaluate thermal characteristics of electro-explosive devices (EED). The thermal response in voltage/time profile is digitised and recorded on a PC. A software for the analysis of this data has been developed. It computes the heat loss coefficient (Lambda), thermal capacity (Co) and thermal time constant (of the system. These parameters are used for the prediction of the performance EEDs during development stage and also in quality control. A computerised system developed for this purpose is also described in detail.
