INSTALLATION
(WAFER SENSOR)
The following section should be used as a guide in the installation of the
Rosemount 8711 Sensor. Refer to page 5-7 for installation of the flange-type
Rosemount 8705 and 8707 High-Signal 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. Metallic or spiral-wound gaskets can
damage the liner. If the gaskets will be removed frequently, protect the
liner ends. If grounding rings are used, a gasket is required on each side of
the grounding ring.
Alignment and Bolting
1. On 1

/2 - through 8-inch (40 through 200 mm) line sizes, place
centering rings over each end of the sensor. The smaller line sizes,
0.15- through 1-inch (4 through 25 mm), do not require centering
rings.
2. Insert studs for the bottom side of the sensor between the pipe
flanges. Stud specifications are listed in Table 5-4. Using carbon
steel bolts on smaller line sizes, 0.15- through 1-inch
(4 through 25 mm), rather than the required stainless steel bolts,
will degrade performance.
