The Rosemount 3051C transmitter is attached to the process connection by four bolts
and two cap screws. Remove the bolts and separate the transmitter from the process
connection. Leave the process connection in place and ready for re-installation.
The Rosemount 3051T transmitter is attached to the process by a single hex nut
process connection. Loosen the hex nut to separate the transmitter from the process.
Do not wrench on neck of transmitter.
Do not scratch, puncture, or depress the isolating diaphragms.
Clean isolating diaphragms with a soft rag and a mild cleaning solution, and rinse with
clear water.
For the 3051C, whenever you remove the process flange or flange adapters, visually
inspect the PTFE o-rings. Replace the o-rings if they show any signs of damage, such as
nicks or cuts. Undamaged o-rings may be reused.
