DANGER
Explosive environment
Death or serious personal injury
- The products in these installation instructions are not intended
for use in potentially explosive areas.
CAUTION
Electric shock
Minor or moderate personal injury
- Install the product in a currentless condition.
The level transmitter must be grounded. To prevent electrolysis,
the shielding of the level transmitter must be set to the same
potential as the products usually found in the medium, such as
pumps and agitators.
The special cable for the level transmitter must be fitted so that the
pressure compensation in the cable assembly is not crushed. The
cable end must terminate in a dry room or in a suitable terminal
case so that no moisture can get through. In addition, the cable
must not be routed through damp conditions.
For variations in media, a guide tube must be used to prevent
measuring errors in flow caused by sideways movement and by
hitting the level transmitter against the walls of the container.
We recommend using a terminal case with a pressure
compensation element. See section 5.4.2 Terminal case with
pressure compensation element. The terminal case must be
mounted as close as possible to the surface of the medium while
still outside the medium.
The membrane at the process connection of the level transmitter
must not be damaged, otherwise it may result in incorrect
measurements or even media leakage. The membrane must not
come into contact with sharp or hard objects.
