Moisture in Rosemount Transmitters


Thread Starter


Hi there,
well we are getting an issue with almost 40 Rose Mount Transmitters. We cleaned them dryed them but still after 24 hours we use to get mositure again. checked all wires,conduit, found dry. no rain so no chance of rain water in any case..stuck.

An intersting thing is this problem is only with Rose Mount transmitters. we are having other vendors as well like yokogawa but didn't ever face this problem with them.
Are you neglecting to tell us things like (speculating)

- these are mounted on liquid nitrogen lines (cooling/cryogenic)

- in the tropics (high relative humidity)

- the conduit is not sealed off, but open to the atmosphere?
