Installation considerations

For dimensional drawings, see
Device identification
To identify the Rosemount 2130 Level Switch version, look at the labels on the housing and on the
electronics cassette inside the housing. See
information.
Allow adequate space outside tank or pipe
Mount the level switch so that it is removable. Clearance of 1.2 in. (30 mm) is required for cover removal.
Ensure there is sufficient room for electrical connections.
The housing cannot be rotated. Ensure there is sufficient room for electrical connections.
Fit the cover correctly
Ensure that the housing O-ring is sitting evenly and then tighten the housing cover to form a good seal.
Always use Emerson O-rings.
Grounding
Always ground the housing in accordance with national and local electrical codes.
The most effective grounding method for the housing is a direct connection to earth ground with
minimal impedance. Housings with NPT conduit entries do not have an earth ground point and must use
the fork earth.
Do not modify the level switch
Do not change the level switch fork in any way
