3.1 Mount the transmitter
Adjust the transmitter to desired orientation before mounting. Transmitter
must not be securely mounted or clamped in place when changing
transmitter orientation.
3.1.1 Conduit entry orientation
When installing a Rosemount 2051HT, it is recommended installing so a
conduit entry faces downward toward the ground to maximize drainability
when cleaning.
3.1.2 Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and meets requirements of NEMA
®
Type 4X, IP66, IP68, and IP69K. Consult factory if other Ingress Protection
ratings are required.
For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.
Note
IP69K rating only available on units with a SST housing and option code V9 in
the model string.
Note
For aluminum housings ordered with M20 conduit entries, transmitters
shipped will have NPT threads machined into the housing and a NPT to M20
thread adapter will be provided. Considerations for environmental sealing
listed above should be taken into account when installing the thread
adapter.
