Abstract: A method and apparatus for determining the temperature of a hot body by a non-contact technique. It comprises a chopping disc (2) which may be disposed in the path of the radiant heat energy from the object so providing a pulsed output of radiant heat energy directed towards a pyroelectric element (7). Between the pyroelectric element (7) and the disc (2) is a further rotatable disc (4) having a pair of wavelength filters (6 and 6'). A microprocessor (14) operates to rotate the disc (4) to interpose each filter (6 and 6') in turn in the path of the pulsed output from the disc (2) at predetermined time intervals. The consequent output from the pyroelectric element (7) is, after amplification, rectification and smoothing in suitable circuits, fed to the microprocessor (14), which then calculates the ratio of the signal from the element (7) representative of power output through one of the filters, and the signal from element (7) representative of power output through the other filter. In this way the temperature of the hot body is determinable without prior knowledge of the emissivity characteristics of the hot body.

Abstract: Die vorliegende Erfindung betrifft ein Pyrometer, welches insbesondere auch hochtransiente Temperaturvorgänge sehr genau erfassen kann. Das Gerät arbeitet nach dem Prinzip der Verhältnispyrometer, verwendet jedoch keine optischen Filter, sondern fotoelektrische Elemente (8a, 9a) unter schiedlicher spektraler Empfindlichkeiten, vorzugsweise Foto-PIN-Dioden oder Foto-Avalanche-Dioden mit kurzen Ansprechzeiten. Durch nicht der Strahlung ausgesetzte gleichartige Referenzelemente (8b, 9b), die sich in Wärmekontakt mit den Meßelementen (8a, 9a) befinden, werden die thermischen Dunkelströme kompensiert. Bei Ver wendung von infrarotdurchlässigen Optiken (2, 3, 4, 5, 6, 7) und Fotodioden mit Empfindlichkeiten bei 0,8 bzw. 1,6 µm Wellenlänge, kann das Pyrometer schnelle und genaue Messungen bis etwa 2500 °C durchführen.

Abstract: A flame quality analyser for analysing one or more properties of a flame from a burner comprises a fibre optic array (32,33) including a plurality of optical fibres each having a light-receiving end lying in a line and facing the flame. The line may extend parallel to the flame and burner axis (array 32) or may extend perpendicular to that axis (array 33). The light received by the fibre optic array (32,33) is provided as a sheet of light to a monochromator which spreads the light into its component wavelengths. A pair of spaced apart arrays of light detectors is then utilised to measure the light at two discrete wavelengths. This detection produces signals that can be analysed to generate temperature and particles distribution values for the flame across its length or width.

Abstract: A fire sensor discriminates between fires and the flash caused by a projectile piercing the wall of a protected area. The sensor system comprises first and second radiant energy detectors, each sensitive to radiation within different spectral bands. Each detector is coupled to a control signal means for generating a control signal when the radiation sensed exceeds a predetermined amplitude. A third control signal means is responsive to the first and second detectors, and is operative to generate a third control signal whenever the ratio of the amplitude of the energy sensed by the first detector to the amplitude of the energy sensed by the second detector is less than a predetermined value; not generate the third control signal whenever the ratio of amplitudes exceeds the predetermined value; and delay generation of the third control signal for a predetermined period of time after the ratio of amplitudes falls below the predetermined value. An output control signal is then generated only if all three control signals are simultaneously generated. The decay of the flash radiation is thereby electrically simulated, allowing the fire sensor to sense whether a fire develops after the flash passes.

Abstract: In a method for measuring the temperature of fuel particles within a fluidized bed, at the same time with two measurement wavelengths ( lambda 1, lambda 3) additionally a third measurement wavelength ( lambda 2) is used. By means of the information obtained with the latter and by means of the information obtained with said two measurement wavelengths, the surface temperature (Tc) of the fuel particles is calculated in such a fashion that the ratio of the emissivities of the fuel particles and the other fluidized bed material is a non-assumed value in the calculation operation. The apparatus comprises a measuring part (3) outside the fluidized bed combustor, comprising three detectors (3d, 3e, 3f) for measuring the thermal radiation at the three measurement wavelengths.

Abstract: The radiation generated by at least one radiation source is controlled so as to generate a constant radiation intensity, thereby to cause the object to be heated, and the radiation intensity from the object at a first wavelength is sensed until it is equal to the present radiation intensity generated by the at least one radiation source, whereby the temperature of the object has a predetermined value. From that time on, the development of the actual temperature of the object is controlled accurately according to a predetermined programme merely be sensing the radiation intensity from the object at a second wavelength larger than the first wavelength, and using the measuring signal representative of the sensed radiation intensity to continuously control the radiation intensity generated by the at least one radiation source.

Abstract: A method of using multiple single-color pyrometers to correct for the effects of reflected radiation when optically measuring the temperature of a relatively cool surface in hotter surroundings is disclosed. The method includes obtaining pyrometric readings from the surface at two or more wavelengths and thereafter utilizing the readings together with the emissivity of the surface to calculate the surface temperature. In one version of the method the emissivity of the surface being measured is determined by a method which includes heating the surface in an insulated environment and thereafter obtaining readings pyrometrically from the surface once the insulation of the surface is removed. The readings are then utilized to calculate the emissivity by extrapolating the readings to a time zero. In those versions of the method which utilze pyrometric readings taken over three or more wavelengths, emissivity may be calculated through the use of relevant mathematical expressions.

Abstract: A method is proposed of measuring the temperature (T) of objects with unknown radiating capacity on the basis of their own radiation. The method involves the following steps: gathering and focusing of the radiation; selection of N spectral bands, conversion of the radiation in every i-th spectral band into an electrical signal, and amplification thereof; introduction of two pairs of linear combinations of the signals obtained from N spectral bands, and calculation of a ratio. The parameters of the linear combinations are selected so as to ensure that the ratio: first linear combination / second linear combination is equal to the absolute value of the measured temperature.
