No mechanical damage of the shaft sealing, lid sealing, cable gland or
other parts can happen.
Note
An accumulation of dust on the housing does not increase the surface
temperature. However, dust can be safely removed with a damp cloth.
Never use a dry cloth because it may cause an electrostatic discharge. See
the Rosemount 2521
surface temperatures in hazardous area (classified locations) applications.

Function test
A frequent function test may be required depending on the application.
Observe all relevant safety precautions related to work safety (e.g. electrical
safety, process pressure, etc).
This test does not prove if the level switch is sensitive enough to measure
the material of the application.
Function tests are done by covering the forks with a suitable solids material
and monitoring if a correct change of the signal output from uncovered to
covered happens.
