Abstract
1,097,570. Photo-electric pyrometers. LAND PYROMETERS Ltd. Oct. 4, 1966, No. 44272/66. Heading G1A. A pyrometer of the type in which radiation from a hot body is divided by a beam splitter to fall on two photo-cells with different spectral sensitivities is constructed with symmetry about the optical axis so that the angular position of the pyrometer is not important when the radiation from the body is polarized. The hot body is focused by an objective 14 on to a field stop 17 which may contain a lens 18. The field stop is focused by a lens 20 and a transparent mirror 38 which may be unsilvered or lightly silvered on to two detectors 26, 22. The detectors may be of different materials e.g. silicon and selenium or differently treated selenium so as to have different spectral responses. Alternatively a filter (25, 37) may be provided in front of one or both detectors or the mirror may have an interference layer or be made of a material which transmits one spectral band and reflects another. Electrical circuit. The cells 22 and 26 generate voltages across loads 41 and 39 which are compared by an amplifier 40 and any difference energizes a motor 46 to adjust the potentiometer 42, 43 to reduce the difference and move the pen 54 of a recorder. A thermistor 36 compensates for variations in ambient temperature. When the output of detector 26 falls below the minimum level at which the pyrometer will give a reliable reading, relay 59 drops out to energize relay 57. This connects the battery 55 to measuring system so that the recorder pen is driven to its zero position.
