Description

technical field

[0001] The invention relates to a particle size analyzer, in particular to a non-contact particle size analyzer and an application method thereof. Background technique

[0002] The sensor of the non-contact particle size analyzer is a non-contact sensing device. It only needs to install the sensor on the online flange of the measured pipeline without inserting the flue. The depth is no more than the position of the valve plate of the gate valve, but not limited to this size), and an analytical instrument that can monitor the particle concentration and particle size in the pipeline. It is mainly used in chemical industry, iron and steel industry, coal industry, petrochemical industry, which is not easy to maintain or requires particle size measurement. For example, when the particle size analyzer fails, the equipment cannot be maintained under working conditions that cannot be shut down, or the relatively harsh working conditions such as high pressure, high t...
