When we purchased the pressure transmitter , we found that the user is most concerned about the stability of the product. Stability means that after a period of use, the ability to maintain its ability to remain unchanged is called stability, but it affects stability. There are many factors, the following analysis of the factors affecting the stability.
1. Range The first pressure range is accurately selected according to the on-site operating conditions. Generally, Eastcom carries out the auxiliary selection. First, the maximum pressure measurement value to be confirmed in the system equipment must be determined. Usually, the maximum value needs to be selected larger than the medium value. 1.5 times the value, because when measuring some liquid media, when the pressure hits, the peak will fluctuate irregularly, and this fluctuation will break the ring sensor immediately after the pressure, in order to prevent the instrument from increasing the instantaneous measurement value. Large and damaged, need to select a buffer damper to reduce the pressure shock, so when selecting the pressure transmitter , we must consider the pressure range to avoid damage to the instrument.
2, the use of the environment If you need to have a good stability of the product, you must have a strong environmental adaptability, before the choice, should survey its use of the environment, and select the appropriate sensor based on a detailed environmental report, or to take Appropriate measures to reduce the impact of the environment.
There are quantitative indicators of stability, after the expiration of the period of use, should be recalibrated before use to determine whether the performance of the transmitter changes. In some applications where the transmitter is required to be used for a long period of time and cannot be easily replaced or calibrated, the stability requirements of the transmitter to be used are more stringent, if it can withstand long-term tests.
In the final analysis, when using pressure transmitters , the use environment and the selection of the range must be determined before use to ensure that no problems are caused by unnecessary losses during use.
