Wear is a damage consisting in gradual removal or deformation of material on solid surfaces, caused by mechanical (e.g. erosion) or chemical (e.g. corrosion) influences. In machine elements, wear may give rise to material failure or loss of functionality. For the application in question, our client has to measure wear on the surface of rollers in cement mills. Up from a certain depth, reactions are required, generated by a warning system to be developed In this project, we used several robust QuellTech Q6 scanners to cover fully the roller width. Due to the high rotational speed of the rollers, we preferred our fastest scanners for this application. We furthermore developed a software solution and implemented a warning system, based on the critical depth of the wears on the surface. By means of this system, the customer can determine the correct time for exchange of the rollers.

Q6-Lasor sensor – High Speed, High Resolution – Q6 Sets New Standards for 2D / 3D Measurement: Resolution of up to 0.6 µm Profile speed of up to 25.000 profiles/s Measuring ranges between 2 mm and up to 370 mm available Laser wave lengths starting from UV via blue, red and green through to IR The Q6 laser sensor series has already proven its ability in numerous industrial applications demanding a high degree of precision and process stability at increased travel speed. For common environments, connection is established via GIGE interface and GeniCam. Integration with linear axes and robots is possible by means of encoder inputs and trigger option.

Optical sensors function contactlessly. They detect objects independent of their characteristics (e.g., shape, color, surface structure, material). The basic operating principle is based on the transmission and reception of light. There are three different versions: 1. The through-beam sensor consists of two separate devices, a transmitter and a receiver that are aligned with one another. If the light beam between the two devices is interrupted, the switching output integrated in the receiver changes its status. 2. With the retro-reflective sensor, the transmitter and receiver are located in one device. The emitted light beam is reflected back to the receiver by a reflector that is to be mounted opposite the device. As soon as the light beam is interrupted, the switching output integrated in the device changes its status. 3. With the diffuse reflection sensor, the transmitter and receiver are in one device. The emitted light beam is reflected by the object that is to be detected.
