电火工品阻值漂移测量电路

Wheatstone Bridge Used for Detecting the Change in the Resistance of Electrical Explosive

文章介绍了一种基于单臂电桥对电火工品因外界影响而产生的电阻漂移进行实时测量的电路,可以实现不拆机的情况下检测电火工品阻值漂移,并保证安全性。在输出端设计了放大电路,可以直接输出普通仪表监测的直流量,以及说明制作中的注意事项。

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.
