Jiangsu Shuoyun Petrochemical Equipment Co., Ltd.

The autoclave for unsaturated resin and coating equipment is equipped with a gamma radiation source installed inside the reactor, together with upper and lower detectors. The detectors are sequentially connected to a signal processing unit and a control conversion unit. Finally, a current signal proportional to the product of counts from the upper and lower detectors is output to characterize the material inventory inside the vessel. This device solves the problem of inability to online monitor the material inventory of the reactor and conduct continuous production under supercritical working conditions.
