Thickness and width measurement systems are engineered to provide fast, accurate, and repeatable control of linear dimensions in various industrial sheet materials. Maintaining precise thickness and width is critical for ensuring product quality, structural integrity, and compliance with engineering tolerances. These systems act as a high-precision tool that measures thickness and width without physical contact, making them ideal for modern production environments where speed and reliability are essential.
Unlike traditional mechanical gauges, Riftek’s non-contact thickness measurement solutions utilize advanced laser technology to operate in real time. They allow manufacturers to monitor sheet dimensions continuously, detect deviations instantly, and prevent defects before they propagate further down the production line. Whether you need a tool to measure thickness of industrial rubber or a width measurement tool for delicate tapes, our systems provide a non-destructive, high-resolution alternative to manual inspection.
Measuring the dimensions of moving boards, plates, or biological tissues can be challenging due to material flexibility or production speed. Riftek laser thickness measurement systems solve this challenge by using light-based methods rather than physical probes, ensuring a non-destructive thickness measurement every time.
A laser thickness measurement system typically operates using one of two primary configurations. In the single-sensor scheme, a laser sensor for thickness measurement tracks the distance to the upper surface of the material relative to a calibrated base. In the dual-sensor scheme, two sensors measure the distance to both the top and bottom surfaces simultaneously. For width control, the system acts as a non-contact width measurement solution by employing optical micrometers that track the exact position of the material edges.
As a versatile laser thickness measuring device, these systems are unaffected by material texture or vibration. They are commonly used as a machined sheet measurement system to monitor production in real time, even on high-speed conveyors or rotating calender rollers.
Width control is as critical as thickness control for materials like tape, film, rubber sheet, and extruded profiles, where even small deviations at the edges affect downstream cutting, winding, and assembly accuracy. Riftek width measurement sensors use optical micrometers to track the exact position of material edges without touching the surface, eliminating the wear, drift, and calibration drift that come with mechanical edge guides.
A single width sensor is sufficient for narrow materials with a fixed reference edge. For wider webs or materials that shift laterally during production, a two-sensor configuration measures both edges simultaneously, giving an absolute width value that stays accurate even if the material wanders across the line. This makes the system a reliable non-contact width measurement solution for high-speed converting, extrusion, and calendering processes, where stopping the line to check width manually isn't an option.
As a laser width measurement device, the system updates readings continuously and feeds them directly into process control, so operators see width deviations the moment they occur rather than after a batch has already run out of tolerance. The same optical principle used for thickness measurement applies here: no physical contact means no deformation of soft or delicate materials, and no measurement error introduced by pressure from a mechanical gauge.
Riftek offers a wide range of specialized systems designed to act as an instrument to measure thickness across diverse applications:
- Industrial Sheet Materials. Our non-contact thickness measurement equipment is intended for precise control of tapes, boards, plates, and rubber sheets.
- Biological Tissue Cutting. A unique optical thickness measurement solution for pericardium used in heart valve prostheses. The system creates a height map to ensure uniformity before automated laser cutting.
- C-Frame Scanning Systems. For continuous scanning of sheet surfaces, a C-frame mounted device for measuring thickness moves across the material, utilizing a calibration plate to maintain absolute accuracy.
- Calender Roller Integration. Specialized laser thickness measurement equipment designed to mount above rollers, using IR lasers to ensure stable readings even in environments with water vapor.
- Width Measurement. Utilizing a dedicated width measurement sensor, these systems can be configured with one or two micrometers depending on the width of the object.
Traditional contact gauges measure thickness and width by physically pressing against the material. This works for rigid, stable materials moving at low speed, but it introduces problems that become significant in modern production: mechanical wear reduces gauge accuracy over time, contact pressure can deform soft or thin materials, and physical probes simply can't keep up with high line speeds without skipping or lagging behind the actual dimension.
Non-contact laser measurement removes these limitations. Because the sensor never touches the material, there's no wear to compensate for and no risk of marking or deforming delicate surfaces like thin film, rubber, tape, or biological tissue. Measurement happens at the speed of light, so the system can track dimensions on fast-moving lines and rotating rollers without a drop in accuracy. There's also no need to stop production to recalibrate a probe — laser systems maintain accuracy through reference calibration built into the setup itself.
The trade-off is environmental sensitivity: optical systems need a clear line of sight and can be affected by dust, steam, or strong ambient light, which is why Riftek's calender roller and industrial sheet systems use IR lasers and enclosed optical paths to maintain stable readings even in humid or particulate-heavy conditions. For most industrial sheet, film, and web applications, though, non-contact measurement delivers a level of speed, precision, and material safety that contact gauges can't match.
Modern laser thickness measurement sensors offer outstanding technical performance, providing a robust gauge to measure thickness with micron-level resolution. Key characteristics include high sampling rates, automated calibration, and the ability to support an unlimited number of control points.
An advanced instrument that measures thickness from Riftek can compensate for environmental factors and provide stable readings under harsh industrial conditions. These systems often include a control cabinet and an industrial panel computer designed to receive sensor data, perform statistical analysis, and display real-time results. As a specialized width measuring device, our optical systems provide consistent edge-tracking data for mass production lines.
Riftek thickness and width measurement systems are built to work as part of the production line, not as a separate offline inspection step. They can be installed as standalone units for periodic checks or as inline stations within a CNC-controlled environment, with sensors typically mounted directly above or around the material path — for example, in a C-frame configuration that scans across the full width of a moving sheet, or positioned above calender rollers to monitor material as it's formed.
This inline placement allows measurement data to feed directly into a CNC or PLC-controlled process. Instead of just flagging out-of-tolerance material after the fact, the system supports closed-loop control: real-time dimensional data can be used to adjust roller pressure, extrusion speed, or cutting parameters automatically, correcting deviations before defective material moves further down the line. For automatic thickness measurement setups, this turns quality control from a checkpoint into a continuous feedback loop.
Each system pairs its sensors with a control cabinet and an industrial panel computer that collect measurement data, run statistical analysis, and output results in formats compatible with standard industrial protocols. Systems can also be configured for remote operation, making it straightforward to connect Riftek equipment to existing CNC lines, SCADA systems, or plant-wide quality monitoring without redesigning the production workflow around the measurement hardware — a setup well suited to Industry 4.0 environments where data-driven inspection is essential for maintaining thin-film or heavy-plate tolerances.
Laser thickness measurement systems are widely used across multiple sectors, including:
- Wood and Construction. For boards and gypsum plates.
- Rubber and Plastics. For continuous extrusion and calendered sheets.
- Metalworking. As a reliable tool to measure metal thickness in rolling mills.
- Medical Technology. For ultra-precise optical thickness measurement of biomaterials.
- Packaging. Using a width measurement tool to control tapes and packing straps.
In industrial production, "web" refers to a continuous strip of material — film, rubber sheet, tape, or fabric — moving through a line at production speed. A laser thickness measurement system tracks this web without touching it, so the material never needs to slow down or stop for a reading to be taken.
The sensor takes measurements at a fixed point along the line while the web passes beneath or between the sensor heads. Because the laser beam reacts instantly, thickness readings update continuously as the material moves, rather than at fixed intervals or sampled checkpoints. This is what makes the system suitable for high-speed converting and extrusion lines, where a web can move too fast for manual or contact-based spot checks to keep up. Any thinning, thickening, or edge drift shows up in the data in real time, giving operators the chance to correct the process before out-of-spec material accumulates downstream.
