6.7 Transmitter head replacement
Figure 6-18. Transmitter Head Replacement
1. Loosen the nut that connects the transmitter head to the process seal.
2. Carefully lift the transmitter head.
3. On the probe, make sure that the upper surface of the process seal is clean and free
from dust and water. Wipe it clean with a dry and lint-free cloth.
4. Verify the spring-loaded pin at the center of the process seal is properly inserted. When
inserted properly only the plunger is seen above the edge inside the seal hole.
5. If the transmitter head is not mounted directly, attach the protection plug to the
process seal to protect the exposed parts from dust and water. If a protection plug is
not available, then cover the process seal with a plastic bag.
6. Rotate the new transmitter head so the device display faces the desired direction.
7. Tighten the nut. Max torque is 30 Lbft (40 Nm).
8. Configure the transmitter, refer to Section 4: Configuration.
