| Abstract: | This paper gives a way which uses Wheatstone bridge to detect the change in resistance of electrical explosive which is influenced by environment. It can detect the resistance of electrical explosive without taking out of equipment and make the process more safe. A magnifier has been designed to make the output DC strong enough to be monitored with normal instrument. |
