In order to realize the on-line rapid detection and control of density in the production process of emulsion explosives,a new method of indirect measurement of sample density using digital rate technology was proposed,and an on-line rapid detection and control system of sample density was established.Studies have shown that there is a good linear relationship between the density of emulsion explosives and the current output signal of the rate detection system;By comparing the sample density on-line detection test value with the true value,the results show that the density on-line detection accuracy can reach 0.2%,which can meet the needs of production practice.At the same time,the system can also adjust the sample density online according to the feedback signal,which is of great significance to protect the performance of emulsion explosives.
