Description

Technical Field

[0001] The utility model relates to the technical field of level measurement devices, and more specifically, to a simple powder silo level height measurement device. Background Art

[0002] The powder silo level height measurement device is an important equipment in industrial production for monitoring the height of materials in the powder silo. It realizes accurate measurement of the level through different principles and methods, thereby helping operators promptly grasp the material storage situation, optimize the production process, and improve production efficiency and safety. The powder silo level height measurement device can accurately and timely reflect the inventory situation of the powder silo, providing an important basis for the production plan and material management of enterprises. It plays a crucial role in industrial production.

[0003] Existing powder silo level height measurement devices mostly adopt the measurement principles and technical means of radar, infrared, and tuning fork to realize real-time monitoring of the material height in the powder silo. For example: The radar level gauge uses microwave pulses to be emitted to the material surface in the silo. The movement of the material surface modulates the reflected wave, and the modulated reflected wave is received by the radar probe. By measuring the time required from emission to reception and then converting the time into distance, the level height measurement is achieved.

[0004] However, due to the fact that the powder materials in the silo are easily affected by the ambient temperature and humidity, the powder is prone to adhere to the measurement devices such as radar, infrared, and tuning fork, thereby causing the level height measurement to malfunction.
