Ring sensors / Tube sensors
That is how ring sensors / tube sensors function
There are ring sensors and tube sensors for various applications in different technical designs. The ring sensors are, as their name suggests, of ring-shaped design. The detection range is inside the ring. Ring sensors exist as photoelectric sensors that operate similar to a light barrier. They can, for example, be used for flow control of liquids. Widely spread in automation are, however, inductive ring sensors and tube sensors. They make use of the physical principle of induction. The sensors generate an electromagnetic field and measure influences on it. If a metallic part passes the detection zone, this is detected on the induction field on the basis of the changes. Due to their design they are characterised by a high resolution at a short response time. Inductive ring and tube sensors are manufactured as a static and dynamic version. Static sensors are suited for stow control or for the detection of relatively large metallic parts such as screws, nails and nuts. To detect small parts the dynamic version of the sensors is better suited. Tube sensors are especially suited for subsequent mounting on non-metal tubes.
Applications in automation:
- Detection of small metallic parts
- Wire break monitoring
- Stow control with feeding tubes
- Ejection control during production
- Counting parts
- Flow control of metal objects
