What is the difference between Rosemount 3051 and 3051S?
Thread Content
Our factory has used some 3051S transmitters. I see there is a difference in appearance. I don’t know what other differences there are. Which one is more expensive?
3051: Precision of 0.075%, range ratio of 100:1, with a 5-year warranty for stability and service life； 3051S: Accuracy of 0.04%, range ratio of 200:1; stability and service life guaranteed for 10 years ； That's all I know ；
New products, high price, high precision, long lifespan. The most important thing is that many domestic manufacturers produce imitation 3051 products; new versions are introduced to distinguish them.
Reply to 2# cnooczhouyx: Is the accuracy of 3051S, at 0.04%, that much different from that of 3051?
When measuring differential pressure, it is essential to choose the 3051s; although the measurement range of the 3051 is the same. This is based on our experience in making product selections. We have been working with Rosemount for a long time – we often attend training sessions provided by Rosemount, and we have sold their wireless products as well
3051s is high-precision, different from 3051c / 3051T
