Pneumatic infrared ray detector for use in gas analyzer |
摘要 |
A pneumatic infrared ray detector for use in a gas analyzer provided with a gas-slowly leaking mechanism capable of not only controlling a quantity of gas leaked in high accuracy but also increasing a range capable of controlling said quantity of gas leaked is provided. A body is provided with gas chambers and a detecting gas chamber and the respective gas chambers are communicated with said detecting gas chamber through gas passages. A ring-shaped leak-controlling sheet on the bottom surface of the detecting gas chamber is provided with a groove-like gas-leaking passage between the inner and outer circumferential edges thereof and a ring-shaped diaphragm and a vibrating diaphragm are built up on said leak-controlling sheet to be fixedly pressurized by means of a cover plate through a pressurizing member and a plate spring.
