Mounting

Flush mounting or non-flush mounting types
There are two different types of capacitive sensors:
Fig.1
Flush mountable
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 material to be detected comes into contact with the active
area of the sensor (e.g. level monitoring of bulk materials or liquids).
