This equipment is typically an automatic or semi-automatic machine designed to measure the breaking load and elongation at the breaking point of single yarns. It operates by holding one end of the yarn stationary while the other end is pulled at a fixed speed (constant-rate-of-extension or constant-rate-of-traverse). The force is measured by a load cell and the elongation is measured on a linear or digital scale.
Specification/Features
- Maximum Load Capacity: Ranges from 5 kg (approx. 50 N) to 30 kg (approx. 300 N) or up to 2.5 kN.
- Speed of Traverse/Testing Speed: 20-1200 mm/min or a fixed speed like 300 mm/min.
- Effective Stroke/Grip Distance: 8 inches minimum to 20 inches maximum, or up to 800 mm.
- Data Acquisition: Modern machines dynamically sample data at high frequencies, such as over 800 Hz, for accurate peak detection.
- Automation Grade: Available in both automatic and semi-automatic versions.
