The Application of Pirani Vacuum Sensor in Vacuum Leak Detection

SONGJIANG, China - July 6, 2021 - PRLog -- The advancement of modern science and technology has promoted the development of vacuum equipment. Vacuum equipment is widely used in sealed containers in many production processes, such as aerospace, military industry, photovoltaic power generation and other fields. It is an indispensable and important technology in industrial systems. At present, vacuum technology has been valued by countries all over the world, and vacuum equipment, technology, materials and accessories have broad market prospects.

The structure of the vacuum system is the key to the airtightness and leakage rate of the vacuum system. Whether the structure of the vacuum system is reasonable will directly affect the airtightness and leakage rate of the vacuum system. For example, in the process of production and development, the production equipment often has problems in material quality, installation, component fatigue, structural design, etc. This may reduce the sealing performance of the system, cause system leakage, which leads to oxidation and scrapping of workpieces, affecting industrial production.

There are many vacuum equipment, such as a vacuum pump. As a kind of air extraction equipment, it is a device that draws out the air in the container through physical or mechanical means to generate, maintain and improve the internal vacuum state in a closed space. According to the characteristics and requirements of the vacuum pump, the vacuum pump must have good air-tightness requirements, otherwise it is easy to cause failures due to insufficient suction of the vacuum pump, so the air-tightness test of the vacuum pump is required.

The vacuum sensor can be selected to detect the airtightness of the vacuum pump. Swiss Neroxis thermal conductivity gas sensor MTCS2601 is a device whose vacuum level detection is based on the principle of Pirani It requires ultra-low power consumption, has a long service life and is maintenance-free. It is suitable for primary pressure control in harsh environments, requiring power consumption and size limitations, or gas leakage, moisture, or intrusion.

Miniature Pirani vacuum sensor PVC1000 series, a kind of vacuum sensor, provides a breakthrough vacuum measurement solution. Not only is it small in size, but it also has the advantages of having ultra-low power consumption, long service life, low on-site maintenance and low cost.
