For example, in the phosphorus chemical production process, the raw materials are more likely to scale in the production tank, and the scaling of the raw materials in the detector head will affect the accuracy of the test data.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] Example 1

A mounting hole is provided on the side wall of a tank body 3, and a mounting cylinder 4 with open ends is horizontally installed in the mounting hole. One end of the mounting cylinder 4 protrudes from the side wall of the tank body 3. The detector 1 is sealed and fixedly installed on the mounting cylinder 4 through a flange kit 5, and its detection end is located in the tank body 3. The purge device 2 is connected to the side wall of the mounting cylinder 4 through an air inlet pipe 6.
[0018] The utility model is based on the principle of the detector 1 and the material characteristics of the detected medium. By adding an online purge device 2, the detected liquid is prevented from silting up and fouling in front of the detector 1, so that the detector 1 can continuously sense the pressure change, realize the effective and stable operation of the detector 1, and provide real-time and accurate monitoring data for safe production.

The continuous steam purge prevents the phosphorus chemical raw materials from silting up in front of the detector 1. The passage between the pressure level sensor and the phosphorus chemical raw materials being measured is always unobstructed. The pressure level sensor can continuously sense the pressure changes and provide real-time and accurate monitoring data.

The first flange 51 is fixed at one end of the mounting tube 4, and the pressure level sensor is fixed on the second flange 52. The second flange 52 and the first flange 51 are connected and fixed by a plurality of bolts 53 to achieve a sealed connection between the second flange 52 and the first flange 51.
