In such a vast country as China, why doesn’t anyone mention brands like Yokogawa or Rosemount?

Haha, you can sue them and make a fortune. The testing regulations and the manufacturers are two separate things; the testing regulations cannot change constantly. However, manufacturers carry out research and development, and new products can be introduced at any time. Can you say that since the current regulations do not cover your product, manufacturers are not allowed to produce it? Testing procedures are established in accordance with the laws of market development, but they do not force those market laws to take effect

When a major brand enters a market, it must comply with the laws and regulations of that region, right?……

So pushing standards is more important than anything else. If someone has excellent skills, then either have the courage to do things without relying on them. When it comes to business, even if you’re very skilled, you might end up in the same situation.

Does no one look at the pictures? Pictures speak louder than words, and this already provides a good response to the original poster’s doubts. Some people still claim that it violates regulations and suggest taking legal action… Of course, I’m just discussing the matter objectively; this doesn’t mean I am in favor of foreign things. For manufacturers, any requirement related to specifications such as protection levels or precision must be met through permits issued by relevant regulatory authorities. For some imported brands, certain specifications may have been certified by institutions abroad, and while some domestic authorities recognize such certifications, others do not; in such cases, there’s nothing else to do but to conduct the certification again if it can be done domestically. To produce any type of instrument, it is necessary to obtain the corresponding production license; just as domestic manufacturers are not allowed to print PSI and bar as units of pressure on the nameplates of their instruments, large companies too must comply with the law. Take Rossmont’s 2088 and 2090 series as an example; these two series can print PSI values, as they are of purely foreign ownership. In contrast, transmitters from other series are of joint-venture origin and cannot print PSI values. If you want the nameplate to show the PSI unit, I’m sorry – the manufacturing company can only import it, as domestic regulations do not permit it, and they certainly won’t take the risk of violating the law for your order. It’s not cost-effective. But some intermediaries might have ways to do it, you know... Foreign-funded companies or joint ventures, in my opinion, tend to abide by regulations more closely. I’d also like to give friends a tip: we’ve found that some big brands make oral promises that their products have certain certifications, but some of these certifications require corresponding certificates, such as SIL1/2/3, and these certificates must be provided to the customers – each device should come with a paper certificate, rather than just one certificate for all of them. If you ask the company to issue such certificates, they might not be able to do so, because they haven’t undergone any certification by official regulatory bodies; what they have is just something they created on their own, which isn’t valid at all.
