In production work, a pressure gauge is a specialized instrument device used to measure the pressure of a specified object. Therefore, the basic requirement for this type of instrument equipment is to ensure the accuracy of the indication. In practical applications, the common faults of stainless steel pressure gauges are mostly related to inaccurate instrument readings. Of course, there are many reasons for the inaccurate indication of stainless steel pressure gauges. Next, we will analyze and discuss this issue.
In fact, there are many factors that may have a certain impact on the measurement accuracy of stainless steel pressure gauges. For example, there are many external factors that can affect its performance. This is because the instrument may experience inaccurate readings when affected by some external factors, such as temperature, vibration, and overload, which can cause the pressure instrument to indicate accurately. When pressure instruments operate in high temperature, high vibration, or overload environments, the internal elastic components will be in a long-term deformation state, causing deformation and unable to display pressure values normally.
As a user, if you want to avoid adverse effects caused by external factors, it is necessary to take preventive measures in advance to prevent stainless steel pressure gauges from working in high temperature, freezing, and vibration environments, or to provide anti high temperature, anti freezing, and anti vibration protection for these environments. At the same time, the instrument should maintain the pointer indication below 2/3 of the full scale of the pressure gauge during operation to avoid the impact of overload operation.
In fact, during the process of pressure measurement, there are many situations that can lead to inaccurate measurements. For example, when measuring, if the pointer of a stainless steel pressure gauge is not at zero position, it will directly lead to inaccurate indication. The main reasons for this fault are the loss of elasticity of the elastic element, the loss of elasticity or detachment of the balance spring, the deformation and jamming of the pointer, or the blockage of the internal pipeline of the instrument. After the pointer is not at zero position, it needs to be repaired in a timely manner and recalibrated to zero position.
In addition, during the measurement period, there may be abnormal shaking or immobility of the stainless steel pressure gauge pointer. The former is mainly due to damage to the balance spring, immobility of connecting rods or gear bolts, bending of the central axis, and blockage of pipelines. The latter is mainly due to the malfunction of the three-way plug of the stainless steel pressure gauge, pipeline blockage, stuck pointer or loose gear, etc
