Measurement Methods and Sensor Technologies: The document provides a comprehensive analysis of various measurement methods and sensor technologies used in determining the thickness, density, moisture, and permeability of materials. It highlights the principles of operation, advantages, and applications of each method.
1. X-Ray and Beta Transmission: These methods involve the weakening of radiation as it penetrates a material, allowing for the determination of basis weight and, if density is constant, material thickness. X-ray tubes can be turned off, unlike beta emitters, and no radiation protection is needed for X-ray energies below 5 kV in Europe. Suitable for nonwovens, films, textiles, and more.
2. Infrared (IR) Measurement: Materials absorb light in the infrared range, which can be used to determine moisture content and basis weight. Effective for measuring residual moisture and distinguishing materials with specific absorption spectra.
3. Microwave Resonance Measurement: Involves comparing a reference microwave with one influenced by water to determine moisture content. Suitable for non-metallic products with varying moisture levels.
4. Laser Triangulation and Light-Band Shadowing: Laser triangulation calculates distance through angle measurement, while light-band shadowing measures thickness by detecting shadowed areas. Ideal for flexible and structured products.
5. White Light Interference: Measures coating thickness through interference of reflected light waves. Suitable for transparent layers and films.
6. Air Flow Measurement: Measures air permeability by suctioning air through the material. Used for textiles, nonwovens, and composite materials.
7. Sensor Selection and Applications: The document lists various sensors and their applications across different industries, including polymer extrusion, coatings, nonwovens, textiles, paper, and building products. Key sensors include Gravimat FMI/DFI for beta transmission, Gravimat FMX-T for X-ray transmission, and Infrascope NIR for IR measurement.
8. Gravimat FMI/DFI Sensor: Features include insensitivity to product flutter and edge curling, high scanning rates, and cost-effective operation. Benefits include non-destructive measurement, material savings, and increased production quality.
9. Gravimat FMX-T Sensor: Features include non-radioactive, high resolution, and suitability for single-component products. Benefits include accurate basis weight and thickness determination with minimal maintenance.
10. Infrascope NIR Sensor: Features include availability in transmission and reflection modes, suitable for continuous monitoring of quality parameters. Used in film, extrusion, coating, and paper production industries.
Infrared Sensors: The IR sensors operate by analyzing the absorption spectra of materials in the near-infrared (NIR) range. They can measure moisture content and basis weight non-destructively and continuously. The sensors offer high spectral resolution, allowing differentiation between components with similar IR absorption. The multi-channel function enables simultaneous measurement of multiple parameters.
Device Versions: NIR-T (IR transmission) measures the entire thickness of the product web, while NIR-R (IR reflection) measures coatings.
Microwave Resonance Sensors: The Aqualot HMF-T sensor uses microwave resonance to measure moisture content with high accuracy and stability. It is unaffected by product color or composition and is suitable for thin materials like printing paper and nonwovens.
Laser Triangulation Sensors: The Calipro DML sensor uses laser triangulation to measure product thickness. It is non-contacting and provides high-precision measurements. The sensor is available in single-sided and dual-sided versions, suitable for various materials including nonwovens and PVC flooring.
Light-Band Shadowing Sensors: The Calipro DMS sensor is designed for materials with rough or structured surfaces where laser triangulation is unsuitable. It uses a combination of eddy current and shading sensors to measure thickness, unaffected by material color or transparency.
White Light Interference Sensors: The Optoscope WLI sensor measures the thickness of thin, transparent films and coatings. It can determine both layer and total thickness online, using visible light or IR, and is capable of measuring multi-layer coatings.
Customer Benefits: Non-contact, non-destructive measurements, high accuracy and stability, suitable for a wide range of applications and materials, reduced waste, and improved process optimization.
Support and Service: The document emphasizes the availability of technical support and service, ensuring quick installation and maintenance to maximize customer benefits.

Key systems discussed include the Qualiscan QMS-12, Airpro APM, and Diecontrol APC Pro.
1. Coating Thickness Measurement: The document describes the use of WLI-Interference spectrum for measuring coating thickness on PET films. The method involves reflecting white light on thin layers, where interference patterns indicate thickness. This technique is noted for its high accuracy and insensitivity to product position fluctuations.
2. Air Flow Measurement: The Airpro APM system measures air permeability and pressure drops across product webs. This is crucial for applications in textiles, filters, and automotive airbags. The system offers a dynamic measurement method with a large range and high accuracy.
3. Automatic Die Control: The Diecontrol APC Pro system automates the control of extrusion dies to ensure uniform film thickness. It compensates for variations in thickness or basis weight, leading to material savings and quality improvements. The system is compatible with various extrusion dies and features real-time monitoring and automatic adjustments.

textile nonwoven coating & extrusion battery paper converting The sensors in the scanner traverse precisely from edge to edge across the product web, driven by a frequency-controlled motor. The reversal points, usually the web edges, can be precisely defined in the software or by edge sensors. If there are several measuring scanners in a production line, a “same spot measurement” of the sensors is carried out in identical measuring paths. A synchronous shaft ensures that the emitter and receiver move exactly simultaneously across the upper and lower beams of an O-frame. A processor in the scanner...
