Overview
The PN-SCTF Short range compression meter is an instrument designed and developed according to the national standard GB/T 2679.10 for testing paper and Cardboard Short Span Compression Test. It is suitable for manufacturing paper and Cardboard of cartons and cartons. The instrument adopts modern mechanical design concepts and ergonomic principles, and uses a professional high-speed ARM processor. It has novel design, convenient use, excellent performance, beautiful appearance, and has functions such as parameter testing, display, memory, printing and data processing. It can automatically reset and communicate with the host computer.
Features
1. Adopt new module circuit design, with WIFI Internet of Things function, can save test results to Cloud as a Service, query and generate reports through dedicated QMS quality management system.
2. Pneumatic clamping of the specimen.
3. With statistical function, display average, MAX Maximum, MIN Minimum, Standard Deviation and Coefficient of Variation.
4. High-speed ARM processor, Degree of automation, fast data collection, automatic measurement, intelligent judgment function.
5. Adopt 24-bit High Accuracy AD Converter and High Accuracy Weighing Sensor to ensure the speed and accuracy of force data collection.
6. Modular circuit design for easy maintenance and replacement.
7. Built-in thermal printer, print the test report directly at the end of the test.
Principle
Short span compression refers to the compressive force on a unit width of paper and Cardboard specimens when they begin to break, expressed in kN/m; short-range compression index refers to the Short Span Compression Test divided by Basis Weight, expressed in N.m/g. The test principle is: a 15mm wide specimen is sandwiched between two fixtures 0.7mm apart to compress until it breaks, the short-range compression force is measured, and the Short Span Compression Test is calculated.
Applications
Paper and Cardboard for the Manufacture of Cartons and Cartons
Standards
GB/T 2679.10、ISO 9895、TAPPI T826、QB/T 2386
Steps
Prepare a 15mm wide specimen.
2. Clamp the specimen pneumatically between two clamps 0.7mm apart.
3. Start the instrument for compression testing until the specimen is destroyed.
4. The instrument automatically measures the short-range compression force and calculates the Short Span Compression Test.
5. After the test, you can print the report directly through the built-in thermal printer, or upload the data to the Cloud as a Service through WIFI.
Notice
• Power supply voltage needs to be AC220V +/- 10%, 50Hz.
• The working environment should be indoor temperature 20 +/- 10 ℃, relative humidity < 85%.
• Ensure that the specimen width is 15mm and the fixture free spacing is 0.7 +/- 0.05mm.
• Note that the Instrument Indication Error is +/- 1% and the indication variability is < 1%.
• The instrument weight is about 42kg, and safety should be paid attention to when handling and placing.
