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.
