Capacitive Sensors | Suitability for Use

The following external influences affect capacitive sensors:

Electromagnetic fields
Cross-talk caused by electromagnetic fields
Material-related influences that contribute to detection fluctuations
Size of objects being detected
Sensor size
Passing speed
High and low temperatures
Humidity (rainwater, splashing water, relative humidity)
Pressure, heat, dirt, etc.

Accordingly, the installation and ambient conditions and any normative requirements must be taken into account for reliable operation of capacitive sensors.

Installation Conditions

The installation conditions provide information about optimal installation of the capacitive sensors in the application without restricting their specified function (i.e., their operating distance).

Normative Requirements for Special Applications

To meet normative requirements, such as explosion protection, capacitive sensors must have certain additional qualifications.

Ambient Conditions

Particularities of ambient conditions must be considered so that sensors can meet the requirements placed on them. Corresponding sensor versions are usually available to suit special ambient condition requirements.
