• The sensor should be mounted to a slant

or vertical wall of the hopper using a weld-

on fitting with G1 ½'' thread or appropriate

fixing nut (PUM-G1,5). The front (active

surface) of the sensor should remain 2-5

mm in front of the inner wall (inwards) or

in front of the fixing nut – Fig. 1a, 1b.

• Although the influence of the build-ups

is strongly eliminated, thick sediments

might cause false activation (blocking) of

the sensor (see Fig. 2). The function of the

sensor is safe with a maximum sediment

thickness of ca. 5 - 10 mm depending on

the dielectric properties of the material.

• The sensor must not be installed in places

with direct solar radiation and must be

protected against weather conditions. In

case the installation at places with direct

solar radiation is inevitable, it is necessary

to mount a shielding cover above the

sensor (Fig. 3).

• If possible, mount the cable from the

sensor down and let there a draining loop

to avoid intrusion of humidity (Fig. 4). The

cable gland as well as the connector's

safety

screw

sufficiently.

• The placement of the sensor must be

carried out in such a way that the material

flow from the filling point does not

interfere with the sensor's scanning field.

Othrewise false activation (blocking) of the

sensor could occur (Fig. 5).
