Process connections
The Rosemount 8721 sanitary sensor is designed using a standard IDF fitting as the basis for
providing a flexible, hygienic interface for a variety of process connections. The Rosemount
8721 Sensor has the threaded or “male” end of the IDF fitting on the ends of the base sensor.
The sensor can be directly connected with user supplied IDF fittings and gaskets. If other process
connections are needed, the IDF fittings and gaskets can be provided and welded directly into
the sanitary process tubing, or can be supplied with adapters to standard Tri-Clamp
™
process
connections. All connections are PED compliant for group 2 fluids.
