Rosemount 8700 Series
INSTALLATION
(FLANGED SENSOR)
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 2-10 for installation of the wafer-type Rosemount 8711 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. All other
applications (including sensors with lining protectors or a grounding electrode)
require only one gasket on each end connection, as shown in Figure 2-8. If
grounding rings are used, gaskets are required on each side of the grounding
ring, as shown in Figure 2-9.

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