Mounting
Flush mounting or non-flush mounting
There are two different types of mounting for capacitive sensors:
For flush mounting in metal or other materials. These sensors can be mounted close
together (see Fig. 1 and 3) and are specially designed for contact-less detection of solids or
liquids through non-metal containers (max. wall-thickness 4 mm)
For non-flush mounting in metal or other materials. When mounting two or more sensors
side by side a space / free zone must be provided (see Fig. 2 and 4). These sensors are de-
signed for applications where the detecting material comes into contact with the active area
of the sensor (e.g. level monitoring of bulk materials, pastes or liquids)

Two opposite sensors have to be mounted with a distance of at least 2,2 times of the oper-
ating distance (distance "a").

For non flush mountable sensors, the zone without a thread has to be mounted with a dis-
tance of at least 1,5 times of the operating distance from the damping material (distance "b")
*If this dimension is reduced, the sensitivity is reduced.
