Title: Condenser microphone type infrared detector for gas analyser
Inventor: SOTANI TOSHIYUKI
IPC: G01N21/37
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To take out only the change of electrostatic capacity caused by the displacement of a diaphragm by dividing a fixed electrode into two electrodes. SOLUTION: Infrared rays from a light source 12 are made to pass through a comparison cell 11 to be incident on a gas chamber 51. At the same time, when infrared rays from a light source 14 are made to pass through a sample cell 13 into which sample gas B flows to be allowed to be incident on a gas chamber 50, the quantity of infrared rays incident on the gas chamber 51 is larger than that of infrared rays incident on the gas chamber 50. Therefore, the diaphragm 55 is largely displaced at the central part thereof and small displaced at the peripheral part thereof by the pressure due to the expansion of the gas in the gas chamber 50 to change the electrostatic capacities C1 , C2 of the equilibrium plate condenser formed from a main electrode part 2 (auxiliary electrode part 3) and the diaphragm 55. The difference ▵C between these capacities C1 , C2 is detected by a processing system. As mentioned above, since a fixed electrode 1 is divided into two electrodes 2, 3 and the output of the electrode 3 is subtracted from that of the electrode 2, the noise caused by fluctuations of temp. is removed and only the change of electrostatic capacity caused by the displacement of the diaphragm 55 can be taken out.
