A pressure gauge is a device used in production and daily life to measure pressure, and the most important aspect when using such a gauge is the accuracy of its readings. Whether a pressure gauge gives accurate readings and whether there are any errors depends not only on factors related to the gauge itself, but also on external factors that can affect its readings. We at Boyi Pneumatic are here to share more information with you. For more related content, please search for Boyi Pneumatic and visit our official website. We look forward to communicating with you. 1. Influence of vibration on pressure gauges: Pressure gauges may also exhibit inaccurate readings in environments with vibration. Intense vibration can directly cause deformation of the elastic elements in the pressure gauge, affecting its sensitivity and accuracy, as well as the user’s ability to read the indicated pressure value. The measures to prevent vibration in pressure gauges mainly involve installing buffering devices and shock-absorbing devices. 2. Impact of overload on pressure gauges: Overload operation of a pressure gauge does not simply mean that its indication reaches the maximum value on the dial; in fact, when the reading exceeds 2/3 of the full scale, the elastic elements of the pressure gauge are already operating near their limit. When a pressure gauge operates under overload conditions for an extended period, its internal elastic components such as bellows and diaphragms lose their elasticity due to being in a state of extreme or near-extreme deformation for a long time, eventually suffering permanent deformation. 3. Pressure gauges are affected by temperature. Pressure instruments measure pressure primarily by relying on elastic components such as Bourdon tubes inside them. In environments with high or low temperatures, these elastic components can deform due to the influence of heat. Especially in pressure gauges that operate continuously in high-temperature media, the elastic components may suffer permanent deformation, which in turn leads to errors in the readings displayed by the pressure gauge. When using pressure gauges, it is essential to minimize the impact of temperature on their indicated values. The most direct and effective way to do this is to prevent the pressure gauge from operating in extreme temperature conditions; if this cannot be avoided, then measures should be taken to protect the gauge from high or low temperatures, such as installing condensation prevention devices or insulation mechanisms on it.
