Abstract
PURPOSE:To detect ozone concentration efficiently, by measuring the absorptivity of infrared-rays of 9-10mum by using a pyroelectric infrared-ray detector. CONSTITUTION:In case 23 equipped with window material 22 made of an infrared- rays transmissive material (e.g., germanium), electric circuit element 25 and platelike pyroelectric element (e.g., PbTiO3 having electrodes provided on both its surfaces) 26 are held on bottom plate 24 to form pyroelectric infrared-ray detector 31. At both ends of case 30 having an opening part, infrared-ray light source 32 and said detector 31 are installed with their optical axes agreeing with each other and between the two, filter 33 permitting light of only 9-10mum to pass through it is provided closely to light source 32 to form an ozone concentration detector. As for the said detector, infrared-rays of 9-10mum from the light source via filter 33 are absorbed in proportion to the concentration of ozone in the air before reaching detector 31, so that the ozone concentration can be measured by measuring the output of detector 31.
