Submergence protection IP68
The remote mount 8721 sensor is rated IP68 for submergence to a depth of 33 ft (10 m)
for a period of 48 hours. IP68 rating requires that the transmitter must be remote mount.
Installer must use IP68 approved cable glands, conduit connections, and/or conduit plugs.
For more details on proper installation techniques for IP68, reference Rosemount
Technical Note 00840-0100-4750 available on www.rosemount.com.
Sanitary fitting torque
Hand tighten IDF nut to approximately 50 in-lbs [5 1/2 Newton-meters (N-m)] of torque.
Re-tighten after a few minutes until there are no leaks (up to 130 in-lbs [14 1/2 Newton-
meters (N-m)] of torque).
Fittings that continue to leak at a higher torque may be distorted or damaged.
Compression-limiting gaskets are used to meet EHEDG Document 8. These gaskets limit
over-torque.

Physical specifications
Mounting
Integrally mounted transmitters are factory-wired and do not require interconnecting
cables. The transmitter can rotate in 90° increments. Remote mounted transmitters
require only a single conduit connection to the sensor.
