INSTALLATION (WAFER SENSOR)

Gaskets

Alignment and Bolting

The following section should be used as a guide in the installation of the Rosemount 8711 Sensor. Refer to page 5-7for installation of the flange-type Rosemount 8705 and 8707 High-Signal sensor.

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.

1.On 11/2 - 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.
