Static Stress-strain Testing And Analysis System - SE-884U
SE-884U Static Stress-strain Testing and Analysis System is a LCD static strain tester specially designed for laboratory. Each hardware includes 8, 16 or 24 measurement channels. Each measuring channel can measure force, displacement or strain. When measuring, the functions of sampling control and data analysis are realized by LCD or computer. The system can be widely used in the static structural performance test of universities, industrial research institutes, engineering testing sites and product development process.
It can realize multi-channel parallel acquisition and high-speed and long-time continuous sampling.
One computer can control multiple acquisition instruments for sampling, which can meet the needs of multi-channel and high-precision measurement.
The computer communicates with the instrument through Ethernet, carries out parameter setting (range, sensor sensitivity, etc.), clearing, sampling, stopping and other operations of the collector, and transmits the sampling data in real time.
It can cooperate with various bridge sensors to accurately test the force, pressure, displacement and other physical quantities.
Any measuring point can be set as compensation measuring point, or common compensation terminal can be used for compensation.
According to the output sensitivity of the sensor, the unit dimension of the measured physical quantity is normalized and displayed directly.
According to the output sensitivity of the sensor, the unit dimension of the measured physical quantity is normalized and displayed directly.
DC power supply can be used, and lithium battery power supply module can also be selected.
LCD control function, screen size is 7.0 inches.
