Rosemount and Yokogawa pressure transmitters
Thread Content
Rosemount is expensive; so what are the advantages of Rosemount over EJA?
The Rosemount 3051 series are capacitive sensors with a precision of ±0.065%. The EJA210A is a single-crystal silicon resonant sensor with a precision of ±0.075%. The Rosemount 2088 series are polycrystalline silicon sensors with a precision of ±0.075%. The above information is taken from the product selection guides; in fact, each brand has its own high-end and low-end products.
Every brand has its own high-end and low-end products. That’s a great way of putting it!
The pressure transmitters from these two brands are both top-quality products available today; each has its own advantages, so either one would be a good choice at the same price range. There are many fake products on the Rosemount market.
Well, Rosemount isn’t just about selling products; what we aim to do is provide users with solutions that help them build intelligent factories, and assist them in achieving those goals they wish to accomplish but haven’t been able to do so for various reasons, thereby achieving a win-win situation. In 2017, we worked on solutions for intelligent factories; by conducting preliminary discussions, inspections, site visits, and assessments with different users, and after analysis by industry experts, we provided customized solutions. I hope this can help everyone. Haha, is it too formal?
Several companies use Rosemount more often; Yokogawa is hardly used at all :lol
Why can’t I find the model specifications for Rosemount 3051CD series transmitters using the few letter codes at the end of the model number? Is it because it is an imported product and there are separate model specifications? I no longer have the specific model number; I helped someone in a QQ group look it up, but we couldn’t determine it. I remember that once the dimensions of the double flanges were found, the letter codes didn’t match, and the rest of the details were also different.
It depends on where you use it; for micro-differential pressure, only Romon’s products can be used. However, the advantage of the single-crystal silicon resonant type over the capacitive type is that it will not be damaged if the medium at the pressure guiding port freezes slightly.
To be fair, Rosemount has a longer service life, and its sensors are quite good
As far as I know, the EJA E series from Yokogawa is currently more expensive than those from Rosemount; in some models the prices are similar. In the past, the A series was indeed cheaper than Rosemount’s products, but that series is no longer available. It’s understandable given the different focuses and development strategies of each company. In the power industry, pressure transducers are mostly manufactured by Rosemount, with few options from Yokogawa. As for service life and product quality, at least I trust Rosemount’s products
Both the voltage and differential pressure models from Romon are selected in strict accordance with the specified criteria. If what you say is true, then your model might be a special version – one for which the local office has made adjustments by adding special codes. In such cases, it’s not possible to find information about it in the regular selection manuals; however, this situation occurs very rarely
