Note
Take protective measures, such as fitting an angled shield (reverse-V shape)
to the silo or selecting an extension tube option, when there are high
mechanical forces.
2.1.3
Mounting location
Take time to assess a suitable mounting location. Avoid mounting the level
switch near the filling point, internal structures, and walls of a silo (or other
vessel). When mounting the extended length versions of the level switch, it
is especially important to consider internal structures. Forcing the level
switch into a small or congested space risks damage to the sensor and could
impair the protection it provides.
2.1.4
Sliding sleeve
Tighten both M8 screws with a torque of 20 Nm to establish a seal and
maintain the process pressure. See

2.1.5
Flange mounting
A suitable gasket must be fitted to provide a seal when the flanges are
tightened.
2.1.6
Hygienic applications
The food-grade materials are suitable for use under normal and predictable
hygienic applications (according to directive 1935/2004 Art.3). There are
currently no hygienic certifications for the Rosemount 2501.
2.1.7
Rotatable housing
The housing of the level switch can be rotated against the threaded
connection after mounting.
