Factors affecting the accuracy of pressure balance elements - Wuxi Sinceriend New Material Technology Co., Ltd.

Pressure balance elements play a key role in maintaining pressure balance in many systems, and their accuracy is affected by many factors:
1. Temperature changes
Temperature fluctuations cause the material of the pressure balance element to expand and contract. This dimensional change affects the sensitivity and accuracy of the element. For example, in a high temperature environment, the elasticity of the diaphragm in the pressure balance device may change, which may lead to deviations in pressure measurement and inaccurate balance adjustment.
2. Mechanical vibrations
Vibrations interfere with the normal operation of the pressure balance element. It may cause internal components to shift or resonate, resulting in erroneous readings. In industrial scenarios with a lot of mechanical vibration, the accuracy of the pressure balance element is easily compromised, so additional shock absorption or stabilization measures are often required.
3. Fluid or gas properties
The properties of the measured fluid or gas, such as viscosity, density and compressibility, will affect the accuracy of the pressure balance element. If the fluid has a high viscosity, it may produce greater resistance when flowing through the element, affecting the accuracy of pressure transmission. For highly compressible gases, the pressure change characteristics are more complex, which also increases the difficulty of accurate measurement and pressure balance of pressure balance elements.
4. Component quality
The manufacturing process and material quality of pressure balance elements play a decisive role in their accuracy. Components made of exquisite craftsmanship and high-quality materials have a more stable internal structure and can better resist external interference, thereby ensuring higher accuracy. On the contrary, components of poor quality may have errors in the initial state, and the accuracy decreases faster during long-term use.
5. Installation and maintenance
The correct installation method can ensure that the pressure balance element can sense the pressure normally. Improper installation, such as incorrect installation position or loose connection, may cause abnormal pressure transmission and affect accuracy. In addition, if regular maintenance is not in place, dirt accumulates inside the component, wear is increased, etc., which will also greatly reduce the accuracy.
