The compact I-Frame design is used in applications that only require a single-sided gauging sensor, such as multi-layer thickness, moisture percentage, and coating thickness. To ensure proper alignment, the rails can be cut by a CNC machine.


o frame styled web gauging scanner frame

The O-Frame is used in applications that require a dual-sided gauging sensor technology, such as beta transmission and x-ray transmission. The top and bottom rails of O-Frames are optically aligned to each other to ensure precision alignment.

The dual-sided sensor, C-shaped frame is used in applications where the web gauging scanner needs to be removed at times, such as an x-ray on hot rolling mills or when an ERS (external reference surface) is used in the system design.

Sensor Technology

Once a scanning frame is selected, industrial gauging sensors are mounted and ride along the tracks, capturing multiple thickness measurements per second. In order to provide the best and most accurate web gauge system, we offer a variety of gauging sensor technologies such as BETA (Sr-90 and Kr-85), terahertz, x-ray, laser, color detection, microwave, and infrared. Our engineers will help you to determine which gauging sensor is best for your application.

Gauging System Software and Reporting

web gauging system software and reporting

We use the best web gauging software available on the market today. The software uses proven control algorithms to reduce startup waste, enable you to run closer to targets, and save on the amount of material used in the process.

During production, the software interprets data readings from the scanning frame and then presents the data to operators in an easy-to-understand display for the current production batch. This can allow them to identify issues as the line is running.

As the systems are scanning, data is stored in a database for further reporting and analysis after production. First, the reporting tools allow you to filter data down to the control zone to help identify issues in your production line. The problems can then be corrected to prevent further quality issues. Second, You can also compare the scans to each other to identify products that do not meet your quality standards, so you can pull these products before they are sent out. And, finally, real-time displays and reports can be customized, allowing you to focus on the data that matters most to your operations.

Improve Operations with a Web Gauging System

By adding a web gauging system to your production line, you can take advantage of many cost savings opportunities, such as reducing the amount of raw materials used, minimizing waste, and recognizing energy savings.

Maximize Raw Materials

Our web gauging system allows continuous thickness measurements of your product to be monitored with such precision that you can reduce the thickness by as little as 0.01mm and realize significant annual savings. For example, in tire production, a typical plant might allow as much as a 0.025 reduction in gauge, resulting in over $1.2 million in annual savings.

Reduce Waste

Production defects cause waste and use resources such as raw material, labor, energy, and time. Defects provide no value to customers and have an impact on your bottom line. Our gauging systems give you the ability to identify defects in real-time, so you can correct issues sooner and minimize waste.

Improved Production
