Shanghai Dachao Electronic Technology Co., Ltd. is a high and new technology company specializing in integrated application, R&D, production, sale and service of GPS for vehicles and car electronics products. It is an industrialized company of high and new technology with full support from Shanghai municipal government and is jointly established by Chinese Aeronautical Radio Electronics Research Institute and China Ruili Group (NASDAQ stock code: SORL) with total investment of RMB 50,000,000 Yuan.
The company engages in development and production of car electronics product ranges, such as mass air flow sensor, electronic oil pressure sensor for diesel engine, wheel speed sensor, crankshaft position sensor, torque sensor, vehicle GPS position terminal, GPS vehicle traveling data recorder, etc..
The mass air flow sensor (air flow meter) is one of important sensors for EFI engine which will transform the air flow inhaled into electrical signal and send it to electrical control unit (ECU) which will be used as one of baseband signals to determine oil injection. It is a sensor to measure the air flow rate which is inhaled into the engine.
The company is supported by environmental test, electro magnetic compatibility, components detection and software test of Chinese Aeronautical Radio Electronics Research Institute and integrates with the design theories and processes of war industry to guarantee the product quality of advanced world standard. MAF-DC ranges are products which are independently developed by the company and applied with the most internationally advanced techniques. They are based on silicon substrate and take seven platinum resistance groups as core units with car-level chips for important units and all integrated circuits. They are bound and welded by professional equipments, processed by 10k dust-free environmental assembly, and tested by complete common and special production test instrumentation to guarantee the quality of air fl
