summary:
The YTBF-60H, YTBF-100H, and YTBF-150H series stainless steel pressure gauges are used to measure the pressure of gases or liquids that are not corrosive in the surrounding environment and have strong corrosion in the measured medium.
The shell structure is airtight, which can effectively protect the internal components from environmental impact and contamination invasion. It can not only measure the pressure of highly corrosive media, but also work under harsh conditions such as vibration resistance and climate protection. In addition, if a flexible pressure hose is used to remotely connect the instrument, it can effectively avoid damage to the instrument caused by the strong vibration of the connecting body of the measured point and the huge swing of the pressure gauge pointer. The YTBF series pressure gauges are widely used in industries such as steel, coal, electricity, chemical, and petroleum.
The YTBF series pressure gauge is an ideal supporting product for domestic users to achieve localization of similar instruments in imported advanced foreign technology equipment.

※ Selection of pressure measuring element (spring tube) material Beijing Haohai Yuntian Instrument answers your questions:
When selecting a pressure gauge, several factors should be considered, including the application medium, accuracy level, surrounding environmental requirements, or a combination of multiple factors. When using, it is important to understand the characteristics of the medium being tested, and then choose a material for the pressure element. Because the service life of materials also depends on temperature, concentration, catalysts that may be added, or other factors that we cannot control.
(9) Work pressure: Static load is used up to 3/4 of the measurement upper limit
Alternating load is used up to 2/3 of the measurement upper limit
