This paper presents a new smoke concentration measurement system, which is designed based on the theory of light extinction. To implement the technique we developed, the hardware system, including a reflecting light path, balanced circuit design, and reasonable data acquisition and processing system, is constructed. In particular, a set of photodiode and preamplifier is specially applied and adjusted...
Study of integrated parameter acquisition and fusion for high-pressure water pump based on virtual instrument was carried out on software platform of LabVIEW. Multi-sensor's parameters are accessed through PCI local bus and RS-232 technology, and then information fusion is realized by three steps: multi-parameter error handling which enables accurate parameters to be acquired, applying multi-sensor...
A new electric-field cage is described, capable of generating uniform DC or quasi-static AC electric fields for sensor calibration and testing. This unique facility is a large parallel-plate capacitor with guard rings to control fringing fields. The cage dimensions and endplate voltages can be adjusted to meet the needs of a variety of experiments. The current size is 2.4 m high by 3.0 m wide (endplates)...
