2006/42/EC
NO
SAFETY
Not a safety component in accordance with the EU Machinery Directive.
■
Do not install the sensor at locations that are exposed to direct UV radiation
(sunlight) or other weather influences, unless this is expressly permitted in the
operating instructions.
■
When commissioning, protect the device from moisture and contamination.
■
These operating instructions contain information required during the life cycle of
the sensor.
2 Notes on UL approval
The device must be supplied by a Class 2 source of supply.
UL Environmental Rating: Enclosure type 1, 2, 4, 4X, 5, 12
Ambient temperature: 80 °C
3 Intended use
The CQF16 is suited for detecting materials in liquid form through non-metallic con‐
tainer walls or with direct contact to the liquids. The sensor compensates for foam,
moisture and deposits and can therefore be used to detect water-based liquids with a
conductivity of up to 50 mS/cm. (e.g. water, milk, honey, syrup, ink, bodily fluids, acids,
alkali solutions)
Application possibilities include:
- Injection molding machines, e.g. adhesives
- Chemical industry, e.g. water preparation, acid and alkaline solutions, solvents
- Packaging industry, e.g. fill level detection, dairy products
The ability of capacitive proximity sensors to detect materials depends on the object’s
density and electrical properties. The sensing range given for capacitive proximity sen‐
sors relates to a measuring plate of standardized steel (ST37).
If changes are made to the product, any warranty claim against SICK AG shall become
void.
