Measuring principle

Web edge control

In the industrial processing of web-shaped materials – whether paper, textiles or transparent films – web edge control with ultrasonic transducers is a key factor for productivity and process reliability. Ultrasonic transducers from SECO Sensor detect even the smallest deviations in the web path in real time and enable rapid correction. Pulsed transducers in multiple arrays have proven themselves for years with customers worldwide.

Our customers use ultrasonic transducers for web edge control for applications such as

Paper processing
Money and newspaper printing
Textile industry
Film processing

Transducer technology for web edge control

Our ultrasonic transducers work opposite each other in transmitter-receiver mode within a typically fork-shaped housing. The web material runs between the two ultrasonic transducers, which continuously transmit and receive sound signals. Ultrasonic transducers measure the transmitted intensity on and next to the material and detect even the smallest deviations from the initial state in real time.

SECO transducers enable precise and maintenance-free web edge monitoring – even in difficult ambient conditions thanks to:

short rise and decay times
high repetition rates
focused sound beam
high signal voltage

Important key data of the SECO transducers

SECO Sensor develops ultrasonic transducers specifically for industrial applications where maximum precision, robustness and reliability are required. The non-contact systems offer clear advantages over conventional solutions – even under difficult conditions such as dust, darkness or transparent materials. For web edge control, we recommend our pulsed transducers or multi-use transducers.

Non-contact
measurement

Wear-free due to contactless measurement, maintenance-free thanks to no moving parts

Excellent signal quality

Proven transducer design and excellent electro-acoustic tuning

Independent of environmental influences

Stable function despite dust, fog, darkness, reflective or transparent surfaces

Real-time reaction to track deviation

High repetition rates due to fast swing-in and swing-out, fast reactions possible

Web edge control in various industries

Discover the versatile application possibilities of ultrasonic sensors in various industries – from printing technology to film processing. Find out how our ultrasonic transducers can optimize your processes!

Textile industry

Web edge control in the production of fabrics and textiles is carried out contactlessly using ultrasonic transducers in measuring forks or multiple arrays. They detect the position of the material edge in real time and enable the web path to be corrected. This minimizes waste and downtimes and maximizes production efficiency.

To the industry overview

Web edge control in packaging with ultrasonic transducers from SECO Sensor

Film processing

In the packaging industry, web edge control ensures precision to the millimeter at high speeds. High repetition rates and fast measurements are possible thanks to short rise and decay times. A major advantage of ultrasonic technology is the measurement of transparent or reflective web materials.

To the industry overview

Printing technology

Web edge control with ultrasonic transducers is used in the printing industry for precise position detection of paper sheets. An arrangement of several transducers in a multiple array enables large-area scanning and fast reaction to the smallest deviations from the ideal web path.

SECO Sensor manufactures high-quality transducers – standard or customized

Ultrasonic transducers ensure reliable monitoring of the web path on modern production lines. Materials with different properties are processed there at high speed. SECO transducers enable measurement regardless of the challenging environmental conditions in industrial production halls. The ultrasonic technology works regardless of fog or dust, as well as reflective or transparent web materials. Measurement on textiles, foils or high-gloss paper is therefore possible without any problems.

Contact us to optimize your sensor technology. Our pulsed transducers in particular have proven themselves for many years in web edge control applications for customers worldwide. Customers also work with multi-use transducers in different sized measuring forks. We are happy to adapt our standard products to your individual project idea or develop special solutions for complex measuring tasks.
