Compared with analog field instruments, what are the special features of the maintenance of intelligent field instruments? Do maintenance personnel need to master programming skills? Some data say that the maintenance cost of smart meters is low. Specifically, where is the low cost and how is it reflected?
Low maintenance cost should refer to maintenance-free. We have used three ABB differential pressure transmitters before. They were imported from the original packaging. We have forgotten how they came from. They have not been touched for 6 years, and we have almost forgotten their existence. :lol I feel that the simplest maintenance is to adjust the valve. When debugging the valve positioner and valve, some sites only need to press an automatic calibration button. In some cases, it is also very convenient to communicate and debug with the manual operator and the valve positioner. There is no need to debug the transmitter. You can easily change some parameters with a handheld smart handheld terminal. Transmitters of the same model can also be uploaded and downloaded. There is no need to debug one by one. Just save the adjusted program and download it. This post was last edited by chmyh on 2009-4-15 09:36 ]
The use of smart meters is to simplify the operation, but many functions are performed through the handheld terminal! Therefore, using the on-site handheld communicator well is the most basic skill!
The debugging and maintenance location is convenient, either on site or in the control room, and the same type of equipment can be processed in batches.
