Fault Detection and Disposal for a Kind of Capacitance-type Signal-transformer
Huang Jian · Control Engineering of China · 2003
In production process, there is the phenomenon that the output showing zero appears with some capacitancetype signaltransformers, which influences parameter measurement or process control. By spot detection and tests in the lab, the fault part has been found out. And by making use of the functioning theory of capacitancetype signaltransformers, it is analysed that the fault is caused by the changes of the sensor's measuring diaphragm or segregating diaphragm. Furthermore, the specific approaches to dispose of the fault has been gotten. In practice, it helps fix the breakdown of several capacitancetype signaltransformers by applying those approaches and has got not bad economic benefit. Therefore the approaches to dispose of this kind of fault are worth spreading in application.
