Device for monitoring concentration of industrial explosive raw material ammonium nitrate solution on line

The utility model discloses a device for monitoring concentration of industrial explosive raw material ammonium nitrate solution on line. The device comprises an ammonium nitrate solution storage tank, and an ammonium nitrate solution output pipeline connected with the ammonium nitrate solution storage tank, and also comprises a refractive index sensor and a temperature sensor which are arranged on the ammonium nitrate solution output pipeline, wherein the refractive index sensor and the temperature sensor are connected with a system processing host; and the system processing host is connected with a display. The refractive index sensor, the temperature sensor and other devices are arranged on the ammonium nitrate solution output pipeline, and the concentration of the industrial explosive raw material ammonium nitrate solution can be rapidly and accurately measured on the production line, so that the production line of industrial explosives is continuous and intelligent. Moreover, the quality of the explosives is effectively guaranteed, the production process is simplified, the number of process operators is reduced, and the production cost is reduced.
