Description and Installation
Capacitive sensors have the unique ability to detect almost all materials, liquid or
solid. Capa ci tive sensors can detect metallic as well as non-metallic objects. How -
ever, their traditional use is for non-metallic materials such as:
• Plastic Industry: resins, regrinds or moulded products.
• Chemical Industry: cleansers, fertilisers, liquid soaps, corrosives and
petrochemicals.
• Wood Industry: saw dust, paper products, door and window frames.
• Ceramic & Glass Industry: raw material, clay or finished product, bottles.
• Packaging Industry: package inspection for level or contents, dry goods, fruits
and vegetables, dairy products.
Materials are detected due to their dielectric constant. The bigger the size of an
object, the higher the density of material, the better or easier it is to detect the object.
Nominal sensing di stan ce for a capacitive sensor is referenced to a grounded me tal
plate (ST37). For addi tional information regarding di elec tric ratings of materials please
refer to our catalogue: "SENSORS".
Installation
1. Mounting the sensor
Mount the sensor in the required position pointing at the target and make sure
that the distance to the target is within the range of the sensor.
2. Supplying the sensor
To supply the sensor, connect blue wire (3) to ground (0 VDC) and brown wire
(1) to + (10-40 VDC).
3. Programming the sensor
Program the sensor as described in the Teach-in guide. The following functions
are programmable: 1. Background adjustment and switch-point setup, 2. Object
adjustment, 3. NO/NC selection and 4. Restore factory settings (1. and 2. are
mandatory).
