What aspects should be considered when selecting ABB TZIDC valve positioners? As the most common digital electrical valve positioner in Switzerland, the ABB TZIDC valve positioner goes beyond the traditional concepts of such devices; it uses TEIP11 as its core component, incorporates microprocessing technology, and features built-in communication functions. Upon installation, it is suitable for controlling rotary and linear actuated valves, offering high positioning accuracy and a large stroke range; automatic zero/scale adjustment simplifies commissioning. Therefore, it is gaining increasing recognition from users, its market share is rising year by year, and today it is used in many different places. To ensure it functions effectively in use, we need to select the appropriate ABB TZIDC valve positioner. So what aspects should we pay attention to when selecting valve positioners for ABB TZIDC? When selecting ABB TZIDC valve positioners for engineering design, the following points should be taken into consideration: 1. It is necessary to ensure that operation at the site is convenient. For some intelligent valve positioner products, the complex setup process affects their performance in actual use. Therefore, we give priority to products that are easy to use. 2. It is required to ensure normal operation in cases of remote installation. As more and more large petrochemical companies are adopting centralized control rooms, the distance between the control room and the intelligent valve positioners on site can be quite large; therefore, the issue of cable voltage drop must be taken into account, otherwise the intelligent valve positioners will not be able to function properly. 3. To meet the requirements of on-site operating conditions and achieve intelligence, we choose intelligent valve positioners in order to obtain their intelligent functions and improve the overall control performance. Therefore, under the condition of meeting on-site operating requirements, intelligence is an important indicator for us. Intelligence includes its communication functions, online or high-line fault diagnosis functions, etc. 4. On-site display is required. For certain intelligent valve positioner products, the lack of an on-site LCD display requires the use of a manual operator for adjustments on site, which increases costs. Additionally, for LCD liquid crystal displays, attention should be paid to their display performance at extremely low ambient temperatures. The above has outlined the aspects to consider when selecting ABB TZIDC valve positioners. It is hoped that by learning from the above content, everyone will be able to select the appropriate ABB valve positioner when choosing ABB TZIDC valve positioners in the future.
