A new method for on-line measurement of explosive density by digital weighing technology is presented. A digital online detection and control system of emulsion explosive density is established, including the design of system hardware circuit, hardware and electrical circuit Installation, and software program connection and debugging. Research shows that there is a good linear relationship between the sample quality and the digital output of the detection system, and the measurement accuracy meets the requirements. Therefore, the system can realize online real-time determination of density of emulsified explosives, and can also realize the automatic feedback and regulation of sensitization effect through PLC so as to ensure sensitization effect and product quality of emulsion explosives.
