Why Rosemount Pressure Transmitter has been the No. 1 in quality in the world for 20 years, the first in sales, the market share increasing year after year, and why a large part of users in China also choose to use Rosemount pressure transmitters. Some Rose The users of Monte are the reasons to explain them:
I. Rosemount's continuous technological improvement with its highly successful products. Keeps product quality consistently ranked first in the world. It has earned the trust of users. The instrument engineer of Shanghai refinery commented on Rosemount, 1151 Transmitter: Our factory. Since the late 1970s, Rosemount's original 1151 transmitter has been used. It is one of the earliest users of China's 1151 transmitter. In the past two decades, we have continuously purchased and used the 1151 transmitter on many devices. The composition of discrete components, consisting of three circuit boards with a precision of 0.25% of the 1151 transmitter to the present one is only a large-scale multi-layer integrated circuit with a precision of 0.1% of the smart 1151. A total of nearly 600 units of 1,151 and 200 3051 transmissions were used. We fully see Rosemount's continuous success improvement on the 1151 transmitter. In the past few years we have also used many other company's products. By using comparisons, we have recently decided that in the future we will mainly consider Using Rosemount 1151 and 3051 transmitters, our experience is that Rosemount Pressure Transmitters have stability and reliability in addition to accuracy, range, and other technical specifications. Outstanding performance. The failure rate is extremely low. In terms of resistance to thunder and lightning strikes. The transmitters of other companies are more or less damaged, but Rosemount pressure transmitters have never had such a situation. We are on Rosemount 1151. And 3051 transmitter is very satisfied.
2. Rosemount has three service centers in Shanghai, Beijing, and Guangzhou, which can provide users with quick and comprehensive after-sales services. The Zhejiang Electric Power Bureau has repeatedly compared through investigations. The final decision was made for the unified use of Rosemount pressure transmission in the power system of Zhejiang Province. The electric power bureau's full-time engineers explained their point of view: Although there are many kinds of transmitters now, we have investigated all the factories and Rosemount pressure transmitters are the best. They have good stability and high reliability. Everyone unanimously expressed that Rosemount's after-sales service is the best. Performance has encountered problems in the factory. Rosemount engineers will respond positively, come fast and solve quickly. Everyone feels very good. In addition, the transmitters sometimes urgently needed by the factory Rosemount engineers can find ways to solve them as quickly as possible. We are satisfied with Rosemount's cooperation over the past two years.
3. The Rosemount product line is very complete. It can meet various technical requirements of users. The petrochemical industry has a wide range of requirements for transmitter materials. The power industry has relatively high pressure requirements for transmitters because there are some transmissions. The device works under high static pressure conditions.
BECHTEL is one of the largest engineering companies in the United States. Its contracting projects include petrochemicals, electricity, and other fields. They have contracted Daya Bay Nuclear Power Phase II and Meizhouwan Power Plant (2*300MW), Intel Corporation Shanghai Joint Venture Plant, etc. Project. Their instrumentation manager is to evaluate the problem of high static pressure transmitters: We have been very careful with the selection of high hydrostatic pressure transmitters for power plant and compressor control. Ordinary transmitters can be used in high statics. Under pressure conditions. However, the stability and accuracy of the transmitter are obviously problematic. According to our experience, Rosemount Inc. is the world's company that specializes in the research and supply of mature products for high static pressure transmitters.
4. The HART protocol invented by Rosemount is the smart transmitter communication and the best configuration protocol. Nearly 80% of the instrument manufacturing companies all over the world use the HART protocol as their communication standard for smart transmitters.
Rosemount's major contribution to instrument development is the invention of smart transmitters for communication, configuration, and diagnostics using the HART protocol. The HART protocol successfully solves the problem of intelligent transmitter communication, configuration, and diagnostics using digital signals and traditional The compatibility problem of 4~20mA DC signal makes the intelligent transmitter transmit the measurement result to DCS with 4~20mA DC signal while it can carry out other communication, configuration, and diagnosis operations without mutual interference. It can realize online communication. State, diagnostic operations. Greatly convenient to use. This is unmatched by other communication protocols.
Indonesia's IPKK company is one of the world's largest paper companies. They recently invested nearly 13.5 billion yuan in Zhenjiang, Suzhou, and built two factories. In their instrument bid specifications, it clearly requires that all smart instruments must use HART. Agreement. Their technical director is to explain their requirements: Our company has factories all over the world. The world's famous transmitters we have used. We will consider the quality of products, prices and after-sales service comprehensive consideration Select the product. But we have no other choice for the communication protocol of the smart transmitter. It must be HART. Because it uses other products that cannot communicate, configure, and diagnose online. It brings a lot of trouble to our production and maintenance. And the HART protocol is now Development of the foundation of fieldbus. We must consider the issue of compatibility with future fieldbuses.
Pressure transmitters look simple, but there are still a lot of things to do. So when you consider using that product, should you also consider the following questions? 1. Are those sales engineers thoroughly introduced you to their products? Situation. Performance How the product line is complete There are no high-static pressure transmitters and micro-differential pressure transmitters. 2. Every company says that they have good services. But the actual situation has advantages and disadvantages. And it varies greatly. Should it be a site visit, check it out. 3. Do those sales engineers tell you what HART or other protocol their smart transmitters use? 4. Which sales engineers tell you about their pressure transmitter reliability? Situation Resistance to Lightning Strokes Overpressure Protection Capabilities...
We believe that when the user has got an understanding of the above issues, he will know why the Rosemount pressure transmitter has become the world's best.
