PIEZOLECTRIC QUARTZ DETECTOR AND ITS USE IN FAULT GASES MEASUREMENT

In this paper, connected with the fault gases measurement, the theories of piezoelectric quartz detector, equipment, crystal select, room form for gases measurement, input way of sample gases, material select for chemical coating, coating make, gases carrier's select,disturbance affected by vapour and other gases and elimination of the disturbance were discussed in detail when piezoelectric quartzdetector was used into gases density measurement. The kinds of piezoelectric quartz detector were discussed in brief. The piezoelectric quartz detector had high sensitivity, anti-interference performance, its equipment was easy, and could monitor the gases density on the spot continually. It could be used into fault gases measurement, and would be a new method to monitor the fault gases continually and automatically.
