Selection of domestic pressure transmitters
Thread Content
Rosemount and EJA are commonly used for pressure transmitters. The domestic brand performs better; could everyone recommend some? It would be great if information on operating conditions, service life/precision, or zero drift, as well as performance in high and low temperatures, could be provided
Domestic brands such as Shangzhiyi and Chuanyi are fairly good, but Shangzhiyi has a very poor user experience – its instruments often show inaccurate readings and lack proper linearity. Chuanyi is not used very frequently; it is recommended to opt for imported brands instead
In our factory, the domestic instruments available are those made by Chuanyi and Kaifeng Instruments, but their performance isn’t very good. They’re used in non-critical areas, so no one pays attention if they break down. I still recommend imported ones

Voltage transformers – if you can’t find any good domestic ones, come to me. Do you need precision at the one-in-10,000 level? As early as 19 years ago, in the year 2000, our small company, Shuaike, was already capable of producing such products. :Lol, no zero drift; the lid is imported, and it’s durable – can last 8 to 10 years without breaking. Using the SC329 from my village, an intelligent meter from a defeated country, would be terrible. :P
I recommend Chuanyi PDS – it has excellent quality, precision, and stability
I used PDS before; it had significant temperature drift. I’m not sure how it is now
For critical machinery, it is more hassle-free to use imported components, as they offer higher stability
The price of Chuanyi PDS does not have a significant advantage over Siemens’ products
