Non-contact inline profile measurement of tread strips (thickness <1mm to 18mm)

The TTP 8301.I is based on the light intersection method. On each material side a line is projected crosswise on the measuring object via a laser light source. The profile is detected by a camera. The geometrical data are calculated from the distance of the cameras and the signals from the lower and upper material side. A long-term and temperature stability is achieved by an automated in-situ calibration.

Special features:

• Accuracy thickness 60µm
• Accuracy width 0.3mm
• 40 profiles per second

The TTP 8301.ET is based on laser triangulation sensors and therefore ensures the measurement being independently from material constants. The system is designed as O-frame, both sensors detect the thickness according to the differential method. In order to ensure highest precision, the laser beams of the sensors are accurately adjusted during the production process using optoelectronic tools which have been specially developed. The system is ideal for monitoring high-dynamically processes due to its high measuring rate. The triangulation sensor applied on the upper side is combined with an eddy current sensor which monitors the distance of the two optical measuring sensors while allowing a software-technical compensation of temperature-induced changes of the measuring gap. Additionally, the compensation sensor is applied according to a special alignment with the measuring task in order to ensure both, a huge measuring gap and highest precision. The TTP 8301.ET is similarly to the TIP8301.ET regarding its functionality. However, they differ concerning the application- or process specific user interface and the corresponding analyses software.

Special features:

• Accuracy thickness ±10µm
• Accuracy width 0.2mm
• Measuring rate to 20kHz

The TTP 8301.CT is based on laser triangulation sensors and therefore ensures the measurement being independently from material constants. The system is designed as O-frame, both sensors detect the thickness according to the differential method. In order to ensure highest precision, the laser beams of the sensors are accurately adjusted during the production process using optoelectronic tools which have been specially developed. The system is ideal for monitoring high-dynamically processes due to its high measuring rate. The O-frame mechanics of the system dispose of a compensation frame which does not vary with temperature and which is used in order to avoid temperature fluctuations of the measuring frame using further sensors. The TTP 8301.CT is similarly to the TIP8301.CT regarding its functionality. However, they differ concerning the application- or process specific user interface and the corresponding analyses software.
