Principle
The testing machine uses a precision digital motor and a digital speed control system as the driving device, and drives the precision screw pair to load after deceleration by the deceleration system to realize the test functions of constant stress, constant strain and constant displacement. Sensor is a two-way force value induction of tension and compression, and collects data through a fully digital closed-loop control system. The single-chip microcomputer performs information sensing, data processing and action control.
Applications
Research Institutes, Universities & colleges, Industrial and Mining Enterprises, Technical Supervision, Commodity Inspection and Arbitration
