Autoeciousness capacitance of capacitance sensor technology

WANG Ai-ling,FANG Ya-min  
The capacitance sensor is of simple structure, the resolution ratio is high, temperature stability is good, having a good adaptability, the trends are of good performance, but the existence of the parasitic capacitance has influenced its performance characteristics seriously, the article has analysed the main reason existing in parasitic capacitance of the capacitance sensor , and dispel several kinds of methods that the parasitic capacitance interfere: Is it urge cable technology , operation amplifier urge technology , whole shielding technology , integrated combination technique is it reduce capacitance of depending on for a living to come to adopt mainly, in order to improve the performance of the sensor.
