As we know, Lead-acid battery is difficult to balance many factors such as the accuracy and the on-line testing requirement. The detecting system, as stated in this article, is based on the vibration test procedure, dynamically following the electrochemical process of the Lead-acid Battery, and collects the real-time state parameters for calculation, analysis and judgment. It also quantizes precisely...
Besides the pH deployment process's non-linear, large hysteretic nature, the system's requirement of real-time and accuracy, the traditional control methods can not get to the high quality control results. The fuzzy control does not rely on a mathematical model of the object. It is very difficult to eliminate the steady-state deviation from the root. Because PI control has a very good scavenging effect...
A strain gage based load cell optimized with final element analysis design. Besides some advanced stabilizing technologies like temperature impact, static overload, computer pattern recognition (CRT) technology is also used to make dynamic simulate and analysis. The multivibration stress release method base on that is creatively used in the production of this load cell. With all this technologies,...
A novel approach for monitoring oil-water interface level and oil level in a single tank is presented. A liquid level sensor has been developed that is suitable to determine the oil-water interface level and oil level. This sensor can realize two sensing functions, namely, inductive and capacitive sensing functions. For achieving this multi-sensing function, the designed sensor employed two coils...
A new method is then proposed for analyzing component of binary gas. An equation for measuring binary gas is deduced theoretically. It is found that the velocity of the ultrasonic wave in the binary gas has a relation with the gas concentration. Although the rate of speed change is very small, change in the phase of velocity is obvious. The realization of the research project is introduced from the...
