ISO1974 Microcomputer Control Textile Tearing Machine
Applications Industry
ZL-9010A Microcomputer control tearing machine is used in paper making, research, product quality supervision, and inspection industries as an ideal testing instrument.
Standards Compliance
Performance parameters comply with ISO1974 "Paper - Determination of Tearing Strength (Ai-li gate Adolf Law)" and GB455 • 1 "Determination of Degree of paper tearing" and other standard requirements.
Working Principle
The instrument operates based on functional design principles. Tearing occurs at a position where potential energy stored in the pendulum is released, converting potential energy into kinetic energy to perform work on the sample. The force required to tear the sample (reflected by the rotation angle of the fan-shaped pendulum) is converted to an electrical signal through a high-precision photoelectric rotary encoder, processed by the control circuit, and displayed or printed as output.
Main Features
This electromechanical integrated testing device features a computer control system using high-precision photoelectric rotary encoder and digital single-chip microcomputer core circuit technology. Through Chinese language LCD display operations with command prompts, it enables simple human-machine dialogue. With advanced technology, complete functions, stable performance, and easy operation, it serves as ideal laboratory equipment for paper, packaging, research, and product quality supervision industries.
