Back Again,
I need to build a test rig that emulates a fuze (well quite a few of them)
Problem :
Building a system to fire the fuzes uses a lot of fuzes.
Resetting the Fuzes also take time and I'm getting rather bored spending 50% resetting my test rig.
Solution :
Build something that can emulate a full rig of fuzes.
I can think of 3 different methods of doing this
1, DC Circuit breakers (sounds expensive)
2, LED indicators (but if you miss it you will never know ?)
3, Some kind of circuit that has a dual LEDS that when dormant is green and when the correct current has been applied it then changes to red and stays in this position until reset. It would also need to give the indication back to the control box of open circuit.
The behaviour that needs to be emulated would need to fit into the following specs,
Bridge wire resistance 1.5 - 2.5 Ohms
No Fire current 0.18 Amp / 5 min
Fire current 0.8 Amp / 4 msec
no firing impulse 0.8 mj ohm -1
firing impulse 2.5 mj ohm -1
Any other solutions ?
I think that even though it may be extra work 3 is the best solution.
Could anyone point me in the right direction ?
