The online measurement device is equipped with a calibration bottle to establish a working curve of the relationship between the element concentration and the count in the liquid. According to this working curve, the concentration of elements in the liquid can be inferred, and to obtain these parameters, the X-ray device needs to be moved between the calibration bottle and the measurement position. The measuring device used in the measurement process is in a closed environment, which cannot be operated by personnel, and it is difficult to achieve precise positioning of the device manually. Therefore, a programmable control servo drive module is selected to realize this function, so as to realize the precise, fast and efficient movement of the measuring device. Its direct drive and control of the measuring device has also become the key to ensuring the personal safety of the operator.

Therefore, when the maintenance protection door is opened, the high voltage of the X-ray tube must be disconnected instantly and the operation must be stopped to reduce the threat to human health.
