Regarding the selection of the hand controller
Thread Content
The 475 has been discontinued, but we’re still using the 375; we want to upgrade to a handheld controller. Should I choose Emerson’s AMS TREX? or is there a better alternative?
What is the quality of domestic manual controllers? Could you recommend some manufacturers with reliable quality? Thank you, moderator!
How about a laptop + HART converter + software?
There are many such manufacturers, especially those producing domestic products. You need to find a manufacturer to test with, and check whether, after using pressure transducers, vortex flow meters, electromagnetic devices, and especially for mass flow communication, the completeness of the menu meets your requirements. As long as the conditions are met, it can be purchased. At least half the price of imported ones, I guess
Thanks for the advice! Find an opportunity to give it a try.
I’m a complete beginner; I’ve come here to learn**
The same problem: at the site, most people still use the old 375 models; the 475 models are available in small quantities and hard to get, even though they have been discontinued
