In recent years, load cell technology development trends.
Internationally, there are two main ways of development: the United States, represented by the first post-military civilian, the first increase in popularity and the way to Japan to represent the practical commercialization to increase after the first universal. China belongs to the latter, despite the application of an earlier study of military departments, but has not converted to civilian use, rapid development and popularity in the past 20 years. In recent years, is a crucial period, the urgent need to improve our overall load cell technology, process and quality standards.
　 International load cell technology trends is that the load cell accuracy, stability and reliability as an extremely important indicator of quality, manufacturing technology and manufacturing process as a core competence, firmly grasp the characteristics of the load cell The problem, production and application of basic research, technology and applied research, the research and is characterized by:
　 (1) product mix in the design and manufacturing process, drawing on engineering design of computer technology to be real and virtual technology, to speed up the development pace of development to reduce the risk;
　 (2) elastomer in the process, from the cell processing technology to the development of integrated processing technology; from the rigid manufacturing to the development of flexible manufacturing; judging from the experience developed to simplify the quantitative analysis of intelligence. Widespread use of flexible manufacturing cells and flexible manufacturing system;
　 (3) of the production process of traditional customs are no longer read the "craft workshops," but technology and management of a systematic project. In order to meet the many varieties, high-volume production to ensure product uniformity of technical performance, the production process to minimize the manual, human control, increased automation and semi-automated process direction. For example: The computer-controlled, man-machine technology systems integration and testing of network-based information technology systems;
　 (4) and the stability and reliability of the stability of the process in dealing with high-temperature, low temperature deep cold, the pulse of fatigue, overloading, and other static methods on the basis of the statute of limitations has come up with vibration, resonance of limitations of the new technology, resonance 10 minutes, The elimination of most of the residual stress.
　 In the above-mentioned design and manufacture of technical support, the load cell structure and the variety and innovation, technology and application of functional scope, the main results are:
　 (1) of the United States Revere-based company has developed PUS atmospheric pressure compensation of dual-use of tension and compression load cell, for high-accuracy testing platform, platform weighing accuracy of up to 5000d;
　 (2) Germany HBM"s successful development of C2A, C16A two different structures of a 100t with a "pressure shell" to protect the load cell explosion-proof, explosion-proof their performance in line with the European EN50014 and EN50018 "d" standard;
　 (3) Si Kaimei U.S. companies to develop a new generation of high-precision stainless steel F60X Series 5-5000kg load cell, accuracy 6000d. For humidity, strong corrosive environment, and water;
　 (4) Germany Saiteneier developed by the company for the bronze elastomer material, with rapid weighing 200 load cell. Characterized by linear, high natural frequency, fast dynamic response. Original oil damping device and overload protection device integration, to ensure that when weighing speed and long working life. 3, assembled a platform for electronic weighing 30kg, accuracy up to 4000d;
　 (5) of the United States THI of 1410 the company developed a 5-30kg aluminum load cell, the accuracy is better than C3 grade level, can withstand centrifugal force and mechanical vibration, built-in special viscous dampers, weighing from time to time to ensure the stability of the fast Time, generally lower than 50ms;
　 (6) VT U.S. BLH has developed a new weighing module, with appropriate functions and components of high weight efficiency, the factory after the "Plug and Play", can automatically adjust the location, not stirred, and the eccentric Vibration impact.
