Water- or alcohol-based media (ε
For example, water, milk and various dairy products, soft drinks, beer
• Extended preconfigured for:
Oil-based media (ε
> 2.4)
r
For example: Oils, ketchup, mustard, mayonnaise, honey, nougat spread
• User; can be freely configured to customer medium:
– Switch point value Output 1/2
– Switchback point value Output 1/2

For dielectric constants (DC values) of many media commonly used in various
industries refer to:
• the Endress+Hauser DC manual (CP01076F)
• the Endress+Hauser "DC Values App" (available for Android and iOS)
Adhesive and viscous media
Setting
Light buildup
Standard
Extended
1)
Surface drying or insulating, non-homogeneous layers can cause the sensor to signal "free" and should
therefore be avoided or eliminated, particularly in maximum safety mode (overflow). The Standard setting
is preferable in this type of application.
Media with foam formation
Setting
Standard
Sensor signal "covered"
Extended
Sensor signal "free"
1)
Very coarsely-pored foam cannot be detected by the sensor.
The device is delivered with the "Standard" setting. Optionally, it can be ordered with
"Extended" as the default setting.
