Principal of Operation
Capacitive proximity switches consist of an RC-oscillator with a special multi-part sensing electrode. When the target material is removed from within the active zone, the oscillator is undamped and the oscillation amplitude decreases. The amplifier of the oscillator voltage and the sensitivity of the sensor can be altered by the built-in potentiometer. This allows for a “calibration” for the proximity of the target to activation of the sensor.
Application and Use
Capacitive proximity switches can be either shielded or unshielded and can be used to detect high, low and intermediate levels in tanks and bins. Shielded sensors can be embedded within a vessel wall so that the sensor face is flush with the inside wall of a vessel. Unshielded sensors detect from the face and from the circumference of the front part of the sensor and therefore cannot be embedded. Vessel contents or target materials to be sensed can be fluids, powders or granulated materials such as PVC powder, dyes, flour, sugar, powdered milk and many other clean and free-flowing materials.
Common applications also include use as end or limit switches for checking and regulating machinery settings. This includes even non-metallic targets such as in conveyor belt positioning and material stacking applications. Capacitive proximity switches can also be used as detectors for counting metallic and non-metallic components.
