Which pressure transmitter is the best?

Which one is better, Rosemount or Sichuan Yi, and which one is more expensive?
Rosemount, but imported products are very expensive. If it is not a special occasion, it is good to use better domestic products. Domestic products should be self-reliant. We also use our own products when doing projects.
Sichuan Yi Xiyi Wuzhong is pretty good in China. Rosemount abroad is also pretty good but expensive.
We originally used 1151, then we used EJA, and then we used E+H in one period, and then we all used Rosemount 3051. I feel that the stability of 3051 and EJA is good. As for the price, just kill it as hard as you can.
I agree with Rosemount, 1151, 3051, invincible: lol It is said that 70% of the petrochemical occupancy rate
Japan's Fuji is very good. It's a small Japanese product, but it's really useful. If necessary 021-61000827 or log in www.tkchina.net
Both 3051 and EJA are good, but 3051 has greater advantages in terms of double flanges and micro differential pressure.
Sichuan Yi EJA and Rosemount are good. These two brands are the main market share of domestic transmitters.
For important occasions, EJA or 3051 is recommended. For unimportant occasions, integrated pressure transformers can be considered. I also really want to support domestic products, but the quality of domestic products must be improved.
Rosemount's is better, and Sichuan Yi's cooperates with Siemens, which is also okay.
Domestic products are basically relatively affordable. Products from Japan are relatively more expensive, but they are better.
I think the choice should be based on the needs of the system. If high accuracy and good stability are required, Rosemount can be used, but it is expensive. If the requirements for the entire system are not high, try to choose domestic products. After all, why should we support domestic products? If everyone does not use domestic products, it will be difficult to improve the quality and performance of domestic products. The quality of Shanghai Runyi Xiyi Sichuan Yi currently available in China is not bad. Personal opinion, for reference only.
Rosemont's bar, 3051 emerson is advertised on the website: Overall performance indicates transmitter performance can reach 0.15% under actual operating conditions, improving loop performance and productivity. Performance over time represents the transmitter's performance over time under changing conditions - 0.125% stability guaranteed for 5 years. - Reduce calibration frequency and save operation and maintenance costs. Dynamic performance measures how quickly a transmitter responds to process changes. - 7 to 10 times faster than other smart transmitters - Increases control and optimization of major loops. - Improve factory safety and productivity. Rosemount All Point Packaged Solutions™ are engineered measurement solutions that combine the best products and installation practices.
ABB is also pretty good. Our company has been using it for four years and has basically had no major problems. The service attitude is also very good. In addition, the American ones are also good.
How about Honeywell's transmitter? ? ?
Both 3051 and EJA are used a lot in our unit, but the pressure transmitter is mainly 3051, and EJA is mainly used for temperature transmitters.
It is recommended to use ROSEMOUNT. Although it is more expensive, it has a long service life and requires little maintenance, which can reduce future maintenance costs. EJA is also good and can be chosen if cost is a consideration. Domestic ones are more troublesome, inconvenient to maintain, and have poor after-sales service quality.
