RODER SRL presents the new DIMES-LTM-LWM series LASER thickness gauges for non-contact measurement of thickness and width with LASER technology.
Used in all applications that call for an economical, easy-to-use system, DIMES-LTM-LWM measures the thickness or width of continuous or discontinuous materials by means of laser light sources.
Measurement is performed without contact and allows dimensional checks even on moving materials, on easily deformable materials and on materials that cannot be measured with traditional contact techniques.
The measurement can be displayed directly on the instrument and can drive programmable alarm thresholds or analogue signals proportional to the measurement.
Data can be transferred to a remote data acquisition system or to a large-format display via cable or wireless connection.
The DIMES-LTM-LWM system can be connected to the DATASINK 100 software package for the automatic acquisition of measurements and alarms. DATASINK 100 can be supplied with the REDAM remote monitor display for remote process control.

Thickness and width measurement on the production line
Systems for measuring thickness and width directly on the
production line for cutting, pickling, treatment and surface coating lines.
Applications built around laser sources of high accuracy and measuring speed, able to operate in environments with industrial characteristics.
The measuring systems are protected from fumes and vapours by an active pressurisation system that ensures accurate, reliable measurement over long periods even in the presence of ambient contaminants.
Automatic LASER thickness gauges
Automatic LASER thickness gauges are an advanced solution for the accurate measurement of the thickness of metal sheet and strip.
This technology combines a high-precision LASER thickness gauge with an automatic traversing slide, which moves the instrument across the whole surface of the material.
Thanks to the controlled movement, measurements can be taken at several points, ensuring complete and reliable quality control.
The system uses a LASER beam to detect variations in thickness with extreme accuracy, giving fast results with no physical contact.
These thickness gauges are ideal for industrial applications where it is essential to monitor the conformity of the product with the required specifications.
In addition, process automation reduces manual intervention, increasing productivity and minimising errors. An essential choice for those aiming at innovation and efficiency in dimensional inspection.

Computerised control stations for displaying measurement data,
displaying trends and for automatic remote control of the system.
Interfacing with management systems for automatic data exchange and programming of inspection recipes.
The connection to IT systems allows inspection reports to be handled with automatic loading of the inspection recipe and automatic downloading of the report of the measurements taken.
Customised software
The software of the DIMES family is built with technologies that make the equipment extremely easy and intuitive to use, so that it can be operated even by unqualified personnel.
The software of the DIMES family is developed from a common development base shared by all the systems, so as to ensure stability and reliability.
The customised modules that allow the system to be correctly integrated into the end customer’s production environment are then added.

Introduction to LASER thickness gauges
LASER thickness gauges are a state-of-the-art technology for measuring the thickness of materials such as strip, sheet, boards and laminates. Thanks to their accuracy and reliability, they are increasingly used in many industrial sectors where dimensional control is crucial to guaranteeing the quality of the finished product and optimising production processes.
How LASER thickness gauges work
LASER thickness gauges use a laser beam to take non-contact measurements. The principle is based on the reflection of the laser beam on the surface of the material and on the analysis of the time of flight or of the displacement of the beam. This technology makes it possible to achieve high accuracy even on materials with surfaces that are not perfectly uniform or that are moving.
Industrial applications of LASER thickness gauges
Metallurgical sector
In the metallurgical sector, LASER thickness gauges are widely used to measure the thickness of strips and sheets during the rolling process. These instruments ensure that the finished product meets the required specifications, reducing scrap and improving the efficiency of the production process.
For example, in steel and aluminium production lines, LASER thickness gauges constantly monitor the thickness of the material to ensure uniform quality, which is essential for applications such as automotive production or construction.
Woodworking industry
In the wood industry, LASER thickness gauges are used to check the thickness of boards and panels during cutting or sanding. Thanks to their ability to measure without contact, they are ideal for delicate or fast-moving materials. This ensures high-quality finished products while minimising material waste.
Plastics and rubber production
For plastics and rubber laminates, LASER thickness gauges provide accurate measurements during extrusion or calendering. This is particularly useful in sectors such as packaging, where dimensional tolerances must be strictly observed to guarantee the functionality and appearance of the product.
Advantages of LASER thickness gauges
Accuracy and reliability
Thanks to LASER technology, these instruments offer high accuracy, often in the order of a few micrometres. This is essential for sectors where compliance with specifications is critical.
Non-contact measurement
Non-contact measurement makes it possible to work on hot, delicate or fast-moving materials without risking damage to the material or to the instrument itself.
Versatility
LASER thickness gauges can be used on a wide range of materials, including metals, wood, plastic and rubber, which makes them extremely versatile.
Automation and integration
These instruments can be easily integrated into automated production lines, allowing continuous, real-time monitoring of production parameters. Being able to program tolerance thresholds makes it possible to identify any deviation immediately, reducing scrap and optimising processes.
Considerations when choosing a LASER thickness gauge
The choice of a LASER thickness gauge depends on several factors, including:
- Type of material: some materials may require specific configurations to ensure measurement accuracy.
- Process speed: in high-speed processes it is essential to use instruments with a high sampling rate.
- Operating environment: in harsh industrial environments, such as those with high temperatures or the presence of dust, robust and protected instruments must be chosen.
Conclusions
LASER thickness gauges are an indispensable technology for thickness control in many industrial sectors. Their accuracy, reliability and versatility make them an ideal choice for improving product quality and optimising production processes. Investing in this technology means acquiring a state-of-the-art tool that guarantees competitive advantages and greater operational efficiency.
