 CAUTION

The products described in this document are NOT designed for nuclear-

qualified applications.

Using non-nuclear qualified products in applications that require
nuclear-qualified hardware or products may cause inaccurate readings.

For information on Rosemount nuclear-qualified products, contact your
local Emerson Sales Representative.

Individuals who handle products exposed to a hazardous substance can

avoid injury if they are informed of and understand the hazard.

If the product being returned was exposed to a hazardous substance as
defined by Occupational Safety and Health Administration (OSHA), a
copy of the required Safety Data Sheet (SDS) for each hazardous
substance identified must be included with the returned level switch.

1.2

Applications

A Rosemount

 2511 Solids Level Switch is used for monitoring the level of

bulk materials in all types of containers and silos.

The level switch can be used with all powdery and granulated bulk materials
that have a density greater than 30 g/l (1.9 lb/ft

3

) and that do not show a

strong tendency to form crusts or deposits.

Typical applications are:

Building materials

Lime, extruded polystyrene foam (XPS), molding sand, etc.

Food and beverage

Milk powder, flour, salt, etc.

Plastics

Plastic granulates, etc.

Timber

Chemicals

The level switch has a threaded, flanged, or Tri Clamp process connection for
mounting it onto a silo (or other vessel). You can mount it on a side wall of
the silo, so that it is level with the filling limit to be monitored. Alternatively,
if it has an extended length, mount it vertically on top of a silo to monitor the
maximum filling limit.

The length of the fork can be up to 157.5 in. (4 m) with an extension tube.
