INSTALLATION
(SANITARY SENSOR)
Gaskets The sensor requires a gasket at each of its connections to adjacent devices or
piping. The gasket material selected must be compatible with the process
fluid and operating conditions. Gaskets are supplied with all Rosemount 8721
Sanitary sensors except when the process connection is an IDF sanitary
screw type.
Alignment and Bolting Standard plant practices should be followed when installing a magmeter with
sanitary fittings. Unique torque values and bolting techniques are not
required.

Sanitary Installation
GROUNDING Process grounding the sensor is one of the most important details of sensor
installation. Proper process grounding ensures that the transmitter amplifier is
referenced to the process. This creates the lowest noise environment for the
transmitter to make a stable reading. Use Table 5-6 to determine which
grounding option to follow for proper installation.
