摘要： A danger detector configured as a point detector includes an alarm housing with an alarm cover, a non-contact heat radiation sensor that is sensitive to heat radiation in the infrared range, and a treatment unit configured to determine and emit a temperature value derived from the detected heat radiation for the ambient temperature in the surroundings of the danger detector and/or an alarm, in the event that the currently determined temperature value exceeds a predetermined temperature comparison value. The heat radiation sensor is arranged in the alarm housing and is configured to optically detect the ambient temperature on the inner side of the alarm cover. The heat radiation sensor may be a thermopile designed as an SMD component.

摘要： A noncontact temperature sensing device receives radiative emissions from a sensed object to measure radiant heat flux and computes a temperature using multiple photodiode sensors, or elements, each sensitive to a different bandwidth of near IR light. The device samples a fluctuating heat source such as a flame or explosion at a fast sampling frequency, and compares corresponding or simultaneous readings in each bandwidth for computing a ratio of the respective bands and determining a temperature via ratio pyrometry. Multiple sensors of adjacent bands each receive corresponding readings of near IR emissions, perform fast, concurrent sampling to mitigate inconsistencies of heat source fluctuations, and compute a temperature based on a ratio between the sampled readings of the different bands. Near IR detection allows common and inexpensive photodiodes to be employed, and the photoelectric rather than thermoelectric sensing allows faster sampling and at a greater distance from the sensed heat source.

摘要： A method of in-situ temperature measurement for a wafer treatment reactor such as a chemical vapor deposition reactor desirably includes the steps of heating the reactor until the reactor reaches a wafer treatment temperature and rotating a wafer support element within the reactor about a rotational axis. The method desirably further includes, while the wafer support element is rotating about the rotational axis, obtaining first operating temperature measurements using a first operating pyrometer that receives radiation from a first portion of the wafer support element, and obtaining first wafer temperature measurements using a wafer temperature measurement device that receives radiation from at least one wafer, the wafer temperature measurement device located at a first position.

摘要： A process is provided for mapping temperatures in an enclosure. A spectral band for a multi-spectral image-capturing device is selected. An intensity-temperature mapping is generated by performing an intensity-temperature calibration based on an intensity of an image pixel in a field of view (FOV) generated by the multi-spectral image-capturing device, a corresponding temperature measurement, and a selected device setting of the image-capturing device. An emitted radiation is detected based on a first spectral image in the FOV. At least one region is determined whether it is poor responsive, which is underexposed or overexposed, such that an accurate temperature is unable to be estimated based on a temperature value associated with the spectral band. Temperatures of the at least one poor responsive regions are replaced with temperatures from corresponding acceptable regions from at least one other spectral image to provide an extended temperature mapping of the enclosure.

摘要： There are many industrial applications in which non-contact temperature sensing is useful for increasing production speed and quality, such as printing, laminating, extrusion, and metal forming. Disclosed is a non-contact temperature determining apparatus which uses two wide wavelength bands integrating sensors to determine the radiance ratio of a target and thereby determine a corresponding temperature of the target. Also disclosed is a non-contact temperature determining apparatus in which a beam splitter passes one wide wavelength band to a sensor and reflects another distinct wide wavelength band to another sensor from which temperature can be determined. A disclosed embodiment of the dual waveband temperature detector improves upon traditional and currently available ratio pyrometers by further reducing the cost of the system, making installation and use easier, and improving temperature detection for low temperature industrial applications.

摘要： Apparatus and method for thermally mapping a component in a high temperature environment. An optical probe (10) has a field of view (14) arranged to encompass a surface of a component (15) to be mapped. The probe (10) captures infrared (IR) emissions in the near or mid IR band. An optical fiber (16) has a field of view to encompass a spot location (18) on the surface of the component within the field of view (14) of the probe (12). The fiber (16) captures emissions in the long IR band. The emissions in the long IR band are indicative of an emittance value at the spot location. This information may be used to calibrate a radiance map of the component generated from the emissions in the near or mid IR band and thus map the absolute temperature of the component regardless of whether the component includes a TBC.
