LI capacitive sensor: Installation guidelines

Distances reflect water in grounded metal tank except where noted

Setting the installation depth:

The unit operates with radial detection characteristics. Therefore, the unit detects media when it reaches the active zone (A=28mm), and media below the probe will not be detected.

The position of the exact level switch point depends on the following factors:

• Characteristics of the media (i.e. dielectric constant, viscosity, etc.)
• Environmental and installation conditions (i.e. presence of foam, turbulence, rate of level change)
• Adjustment of the unit (see Programming section under Setup and support)

The following guidelines should be followed when setting the installation depth:

• Ensure 60 mm (2-3/8”) or more of the probe is below the mounting connection or inside wall of tank.
• Make sure at least half of the active zone (A) will be covered at desired switching point.
• Use supplied stainless steel tube clip to fix the installation depth in a blank hole or use one of the available mounting accessories (see Select Products).
