Rosemount 8732

INSTALLATION (FLANGED SENSOR)

Gaskets

The following section should be used as a guide in the installation of the flange-type Rosemount 8705 and Rosemount 8707 High-Signal Sensors. Refer to page 5-10for installation of the wafer-type Rosemount 8711 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. All other applications (including sensors with lining protectors or a grounding electrode) require only one gasket on each end connection, as shown in Figure 5-8.If grounding rings are used, gaskets are required on each side of the grounding ring, as shown in Figure 5-9.

Flange Bolts

Suggested torque values by sensor line size and liner type are listed in Table 5-1 on page 5-8for ASME B16.5 (ANSI) flanges and Table 5-2and Table 5-3for DIN flanges. Consult the factory for other flange ratings. Tighten flange bolts in the incremental sequence as shown in Figure 5-10.See Table 5-1and Table 5-2for bolt sizes and hole diameters.

See ”Safety Messages” on pages 5-1and 5-2for complete warning information.
