| LTM-SMART | LTM-MAXI | LTM-ULTRA |

The LTM-SMART Thickness Gauging System has been specially developed for high-speed coil-strip material in strip processing lines, the system is used to check the material thickness before and after the processing in order to provide process control default values.
Due to the high sampling frequency, the LTM-SMART system is also used in the flexible roll forming of „Tailored Rolled Blanks“ material, roll profiling, punching and in tube manufacturing.
The LTM-SMART high-performance measuring system enables non-contact strip thickness measurement using two triangulation laser sensors. The combination of a linear axis with stepper motor enables the recording of both a static and a dynamic measurement.
The following measurement modes can be realized by:
• Line measurement
• Micro-traversing
• Macro-travering
• Macro-traversing with track measurement

During the development of the mechanical components, great emphasis was placed on a very high bending and vibration stiffness with a high resistance to temperature fluctuations and is subsequently guaranteed. The connection to the customer‘s control concept is made either via a Profibus or Profinet. On a separate data interface, all relevant measurement data, e.g. is in CSV format.

The integrated calibration unit inclusive the associated measuring standard and the temperature sensor enable the fully automatic adjustment of the system and thus the respective adaptation to changing environmental conditions. The tool used to determine the measuring capability, which is implemented within the LTM-S operating software, enables continuous monitoring of the thickness gauge to ensure that the required conditions are met.

The ROLAND operating software (internal client) LTM-S enables a simple, self - explanatory and reliable operation of the measuring system. Graphical evaluation tools allow the user a quick visual assessment of the corresponding measurement results.
