Do you know how to avoid pressure transmitter failure from selection and installation? The editor has encountered an abnormal situation in this regard, so I intend to share with you here, how the editor solves such a situation, and hopes to provide you with a convenient way. 1. Avoid the failure of the pressure transmitter from the selection. When selecting the pressure transmitter, it is necessary to pay attention to the pressure range of the measured medium and select the appropriate pressure transmitter range. In addition to the measurement range, the turndown ratio is also a very important technical indicator, which will affect the measurement accuracy of the pressure transmitter. When selecting, it is necessary to select the appropriate range and range ratio according to the requirements. In addition, pay attention to the maximum pressure of the pressure transmitter. Generally, 1.5 times the design pressure will be selected. However, it should be noted that there will be pulses or sudden pressure increase in some working conditions. In this case, a buffer needs to be selected. As a protective device for the pressure transmitter to avoid damage to the pressure transmitter. At the same time, it is necessary to distinguish the measurement method and wetted material of the selected pressure transmitter according to the technological characteristics of the measured medium. When the measured medium is dry gas or pure liquid and the viscosity is not high, an ordinary pressure transmitter can be used, and two valve groups are used in front of the meter to prepare for maintenance; if the measured medium is a strong corrosive liquid, viscous For liquids, etc., you need to choose the corresponding corrosion-resistant diaphragm pressure transmitter, and you can also choose a diaphragm pressure transmitter with a convex diaphragm according to the actual situation; when measuring high/low temperature media, you should choose a split pressure transmitter , use a pressure tube or capillary for pressure measurement. When choosing the capillary pressure guiding method, we must pay attention to the requirements of operating temperature to avoid the phenomenon of pressure guiding oil vaporization or solidification in actual use. 2. Avoid pressure transmitter failure from installation. The position of the pressure transmitter's pressure point is clearly stipulated in national standards. When designing, it is necessary to strictly abide by national standards to ensure the quality of automation instrumentation projects. Specific installation For the method, please refer to the relevant standard documents, which will not be described in detail here. The above content is the detailed focus on how to avoid pressure transmitter failures in the selection of models compiled by Xiaobian. I hope it can help you.
