1 Mounting instructions
For mounting, a spanner with SW (spanner width) 11 and 13 is
required.
The sensor housings have two filter elements. The upper one near the
cable glands is used to ventilate the electronics housing. The lower
filter element in the area of the base is used to ventilate the measuring
cell.
The external ventilation is generally used for the lower filter element.
The following illustration shows the mounting location.
