emco NDT 100-S Automatic Wet Expansion Tester for 3 Testing Standards
Automatic Wet Expansion tester according to Fenchel, Mütek CD and MD in one device
The new emco NDT Wet Expansion tester for paper realizes a dynamic measuring principle for the determination of the wet stretch course. The testing of wet stretch of paper is relevant for the assessment of the material behaviour in manufacturing process as well as in application only when a dynamic measurement procedure is used.
The expansion measurement of a paper sample can be performed in different test liquids. In combination with immersion and expansion time the application process can be optimally simulated.
Expansion of paper caused by liquids means the swelling of the fibers by absorption of liquid. Thereby paper fibers swell less in machine direction than in cross direction. Equivalent results arise from wet stretch measurements at standard climatic conditions (23 °C, 50 % rH) and defined counterweights (Fenchel, Mütek CD, Mütek MD).
- Non-contact measurement value acquisition via laser sensor excludes peripheral influences such as friction or counterforces of the transducer
- Digital measurement resolution 0.01 %
- Variable test time from 1 to 900 seconds
- Automatic zero adjustment and compensation of clamping errors
- Graphical representation of the measurement process
- Menu-guided switching between standards possible
- Transfer of measurement data to PC (measurement report)
- Low operating effort due to magnetic clamps (less than 30 seconds)
- Integrated climatic sensor
- Sample preparation with the electric Multi Sample Slitter emco MSS or Sample Cutting emco PZS (optional)
The expansion measurement of paper is used in research & development and quality control for:
- Decor paper
- Poster paper
- Speciality papers
- All papers in further processing
