The Main Function:
Working principle: The instrument is designed based on functional principles. After the pendulum with a certain potential energy in the position to be torn is released, the potential energy is converted into kinetic energy and the work is done by tearing the specimen. The force required to tear the sample (reflected as the rotation angle of the sector-shaped pendulum) is converted into an electrical signal through a high-precision photoelectric axis angle encoder and input into the control circuit. After processing by the circuit, it is output in a display or print mode.
Main Feature:
This instrument is an electromechanical integration test device. Its computer measurement and control system uses a high-precision photoelectric axis angle encoder and digital circuit technology with a single-chip microcomputer as the core. It realizes simple human-computer dialogue through the LCD Chinese display operating prompts and cotton pad input instructions. , with the advantages of advanced technology, complete functions, stable performance, and easy operation, it is an ideal experimental equipment for industries and departments such as papermaking, packaging, scientific research, and product quality supervision and inspection.
Standard:
The performance parameters comply with the relevant provisions of ISO1974 “Paper – Determination of Tear Strength (Elimendorff Method)” and GB455.1 “Method for Determination of Paper Tear Strength” and other standards.
Application Industries:
It is an ideal testing instrument for industries and departments such as papermaking, scientific research, and product quality supervision and inspection.
