| People demarcate torque sensor manually these days in China. So Measurement error produces. We can demarcate torque sensor automatically by high precision small torque standard device. Thus measurement error eliminates.The technology of computer intelligent control technology, Photoelectric detector technology, sensing technology, data acquisition and processing technology are used in the system. The operation of control, collection, processing, storage and Print are made automatically. The computer program controls the standard device's operator. High precision torque measuring instrument collects data and transmit data to standard device via RS-232. The data is dealed with automatically. At last the sensor is demarcated.Above all, the paper introduces the device's collectivity scheme. This part introduces the device structure and controlling program. Secondly, Technology of Visual C++ and computer program are introduced. Finally, Through researching and analyzing the systems uncertainty we know that high precision small torque standard device meet the requirements and can be used to demarcate sensor. |
