Intelligent online testing system for DC resistance

Application: The intelligent online testing system for DC resistance is a new generation of high-precision testing system for online measurement of DC resistance of cables, wires, copper poles, aluminum poles, etc. It adopts a closed constant temperature chamber for measurement, a 17 inch electronic screen display, intuitive reading, high measurement accuracy, good stability, and more convenient automatic range operation. This measurement system has multiple temperature measurement points to make the temperature in the constant temperature chamber more uniform, and can be adjusted to the ambient temperature of 0-70 degrees. The temperature can be automatically adjusted and controlled by PLC based on the conductor temperature and ambient temperature, and the resistance value can be directly converted to 20 ℃. And equipped with a USB port for storing data in EXCEL format, the network port can communicate with the computer, and test data can be saved and printed. Can connect synchronously with multiple windows. This testing system complies with and meets the GB/T3048.4 conductor DC resistance test standard.

Features: No stage or waiting is required for on-site testing in production, and the standard resistance value at 20 ℃ can be directly calculated; Intuitive reading, high measurement accuracy, good stability, and more convenient automatic range operation; High precision; Comes with built-in data storage; Added metal material testing.
