The EDA™ Electro-explosive Devices Analyzer is a universal measuring and control unit serving for precisely-defined ignition of samples of energetic materials or explosive devices, combined with the simultaneous high-speed measurement of dynamic pressure, temperature and emitted light.
The EDA allows for precise adjustment of ignition current value and time for generation of precise constant current, voltage or power impulse. Maximum pressure, burning time, ignition delay time, current and voltage levels, pressure gradient, pressure rise time and/or the burning rate may be recorded and evaluated.
APPLICATIONS
The EDA is a necessary accessory for ballistic experiments with gun and rocket propellants in closed vessels (TSV Series and HPA 1500), as well as for testing electric initiators (fuse-heads, squibs, detonators etc.) in research, development, quality control, qualification and surveillance programs. The explosive and automotive industry, research, development and quality control laboratories around the world rely on the EDA for its precision and reliability
ADVANTAGES & FEATURES
- Compact solution for both proper ignition and high-speed measurement
- Precise current source with guaranteed rise time
- Determination of bridge-wire resistance of ignition elements
- Adjustment of ignition current, voltage or power level and impulse duration
