Which smart locator is better?
Thread Content
We used positioners from Siemens, Fisher, and Memosens on site, and they were all quite good. The Siemens models tend to experience oscillations, while the other two types are too expensive. Are there any other positioners with a better cost-performance ratio?
I haven’t used them specifically; I’m just talking generally. Metso, ABB, Foxboro ECKARDT, azbil, KOSO……
Yamatsu, which is now AZBIL
Yamaki offers the best cost-performance ratio, although it’s a Japanese product
The Fisher DVC6200 is quite good, and Siemens models are also excellent. As for the issue of oscillation you mentioned, if the installation environment experiences significant vibrations, it’s possible to opt for Siemens’ split-type NCS model, which can help prevent oscillations caused by mechanical connections.
Fisher, Messonilan’s locators
Actually, it’s better to use domestic ones; the positioners produced by Wanxun, Hengyang Optoelectronics, Zhejiang University Control Systems, and Chongqing Chuanyi are very durable. The Siemens units we used previously also experienced oscillations, so we switched to Samson’s products. Fisher-Merson-Landis is simply too expensive
