When unpacking the switch, check all components for any external damage. Prior to
EN installation, a functional check can also be carried out. For this, the instrument should be
connected temporarily and the glass prism dipped in and out of a glass of liquid to test it.
5.1 Mounting
Before installation, it must be ensured that the mounting hole and the fixing device for
■
the switches in the vessel are correct in size and dimension.
Mount the switch, pressure-sealed, into the process connection.
■
The glass tip must protrude into the vessel.
■
Following installation, the glass tip should have a distance of at least 10 mm to the
■
opposite wall. This minimum clearance can vary dependent upon the geometry and
surface finish of the wall. Note: With electropolished pipes, the minimum distance to the
opposite surface must be a minimum of 20 mm.
