Jiangnan Industrial Group successfully developed DZC-9 type pyrotechnics resistance measuring instrument

[ China Instrument Network Instrument Development ] Recently, Jiangnan Industrial Group Technology Technology Research Institute successfully developed the DZC-9 type pyrotechnics resistance measuring instrument, and the fire resistance resistance testing technology has achieved new breakthroughs.

Jiangnan Industrial Group Co., Ltd., formerly known as Jiangnan Machinery Factory, is a large-scale backbone enterprise of China Ordnance Industry Group Corporation. It was founded in 1952 and is headquartered in the western suburb of Xiangtan City, Hunan Province. The company is a nationally recognized enterprise technology center, a national defense science and technology industry certified enterprise technology center, a national innovative enterprise, and a national advanced grassroots party organization. It has now developed into a comprehensive large-scale enterprise group with dual qualifications for military and civilian products research and production.
At the end of the 1980s, some special professional productions of Jiangnan Company must use a tester with extremely strict safety requirements and high precision requirements. At that time, domestic similar instruments manufacturers had stopped production, and similar products in Europe and the United States were extremely expensive. Therefore, Jiangnan Industrial Group decided to design and trial-manufacture itself. In just a few months, the “DZC-1 low-resistance measuring instrument” was successfully developed, which ensured the production needs in time.
As the precision requirements of the company's products are getting higher and higher, the measuring instruments developed by Jiangnan Industrial Group Co., Ltd. are also constantly upgraded. The company has created the "two-way DC current measurement method", "AC square wave measurement method" and "two-way comparison measurement method", which broke through the directional interference of weak battery formation, such as the original battery potential and thermoelectric potential between dissimilar metals. A number of technical difficulties have made the measuring instrument evolve from the DZC-1 type to the DZC-9 type.
The successfully developed DZC-9 type pyrotechnics resistance measuring instrument is a special instrument for pyrotechnics resistance measurement. Its biggest feature is the use of two-way comparison test technology, which can work between -40 ° C ~ +55 ° C, test current It is 1 mA, which ensures that the resistance measurement accuracy is one thousandth and the resolution is 0.1 milliohm.
It is understood that the development of these measuring instruments not only ensures the production and scientific research needs of the company in various periods, but also meets the high precision, high safety and wide temperature range of pyrotechnics resistance in many fields such as aviation, aerospace, shipbuilding and military. Measurement requirements.
