Basic understanding of the measurement and control system of tensile testing machine

nowTension testerThe many brands of testing equipment market make customers puzzled. Among the many tensile testing machine manufacturers, customers must pay attention to the quality and accuracy of the test machine. The following content is our company's knowledge about the tensile testing machine measurement and control system:

Tension testerThe measurement and control system (that is, software and hardware), most of the tensile machines on the market currently use 8-bit microcontroller control, with low sampling rate and poor anti-interference ability. In addition, if the number of bits of the AD converter is low, the resolution of the AD converter is low. Then the measurement will not be accurate. Our company's measurement and control system uses the world's advanced 32-bit ARM technology to develop controller Hytest V6.0. This controller is based on the 32-bit ARM platform and runs the time-based multi-task operating system developed by our company. The program runs smoother and the system is more stable. The sampling rate can reach 200 times per second. With the addition of a 24-bit high-precision low-solar sound high-speed AD converter, the entire measurement and control system has more precision and high stability to control the entire test process. The software of the computer is the company's full-digital three-district control software developed over 5 years. There are two control methods (1). PID control and adjustment method (2). Mohu control and adjustment method (the first in the industry). This allows the entire test process to achieve constant force value control, constant displacement control, constant deformation control, low-frequency fatigue control, and arbitrary program control.

By the aboveTension testerA simple explanation of the measurement and control system can easily distinguish the quality of the test machine, and customers can also purchase the test machine more reasonably according to the requirements of their own laboratory.
