Do Rosemount and EJA have PTFE diaphragm pressure transmitters?
Thread Content
As the title suggests, do Rosemount and EJA have PTFE diaphragm pressure transmitters? Could you recommend some other manufacturers of PTFE diaphragm pressure transmitters?
EJA has a similar non-metallic coating, though it’s not PTFE; I’m not sure about Romon’s version, but there are many such third-party adaptations available.
They can all be equipped with diaphragm devices; I’m not sure if this is the same as PTFE you mentioned
This is not high-tech; ordinary manufacturers can achieve it.
In Yokogawa Electric’s EJA and EJX series of transmitters, those with flange connections allow for the use of an additional diaphragm made of PTFE; a small bottle of perfluorinated oil is also provided for applying this diaphragm. It is not necessary to use pressure guide pipes, but an isolation tank can be used.
