CAPACITIVE SENSORS Reliable detection of objects and fill levels

CONTACT-FREE AND REACTIONLESS Capacitive sensors make reliable detection of almost all materials in automation possible. Due to their high sensitivity and capability of detecting both electrically conductive and non-conductive objects, capacitive sensors are used anywhere where other measurement principles no longer work. Together with our overall portfolio of optoelectronic and inductive sensors, you can therefore find solutions for all detection requirements from a single source. SOLID, LIQUID OR GRANULAR Capacitive sensors are able to detect different objects and media without contact...

THE OPERATING PRINCIPLE MAKES THE DIFFERENCE The function of a capacitive sensor is based on changes to the electrical field in the surroundings of its active zone. If the capacitor plate which is arranged behind the active zone is supplied with current, an electrostatic field is generated. This reacts to capacitance changes which are caused by an introduced object. Measurement variables which are interesting from a production-related point of view such as distances or fill levels can be transmitted to the control. ■ Contactless and wear-free operation ■ Detection has no influence on the...

WHAT YOU NEED TO KNOW ABOUT CAPACITIVE SENSORS Basic technical know-how for successful use of capacitive sensors. TWO DESIGNS ARE AVAILABLE FOR YOUR APPLICATION Capacitive sensors are available with embedded and non-embedded design. Embedded-mounted sensors These sensors, which have a linear electrical field, scan solid objects (e.g. wafers, components, circuit boards, hybrids, cardboard boxes, stacks of paper, bottles, plastic blocks and panels) or media through a non-metallic dividing wall at a distance. ■ Also suitable for solid objects with a low dielectric constant ■ Object detection...

THE ROLE OF THE YOUR DECISION-MAKING BASIS DIELECTRIC CONSTANTS £ Capacitive sensors have a unique technical characteristic, which determines their area of use and makes selection easier. 1. Detection of metallic and non-metallic objects, liquids and solid objects 2. Sensors can "see through" certain materials (products in packaging and container walls) 3. Long life expectancy due to semiconductor technology 4. Diverse mounting options 5. Detection with or without contact possible The dielectric constant is a specific material property. This means that materials with large dielectric...
