本文介绍一种采用金硅面垒型半导体探测器的β射线电容器纸测厚仪,它用单源双探头方案以补偿空气层密度变化。仪器灵敏度约为15µg/cm
2
,适合于8—18g/m
2
(即6-15µm)电容器纸生产线上使用。已在电容器纸生产线上运行一万多小时,性能良好。
A
β
-gauge using silicon surface barrier semiconductor detector is described. It has one
14
C source and two detectors
one of which is for thickness measurement and the other is for compensating the density change of air. The
β
-gauge
mounted on a capacitor paper production line
is suitable for on-line test of 8-18 g/m

paper with a sensitivity about 0.15 g/m

.
15000 hours on-line operation has shown that the
β
-gauge's stability and reliability are satisfactory.
