摘要：The invention relates to a more accurate system for calibration and/or characterization of temperature measurement instruments by telemetry, involving a reference unit with thermal gradient defined by a disc with thermal gradient, comprising at least one concentric heat diffuser metal ring, with temperature sensors that generate a staggered radial temperature profile mechanically linked with a cavity of a black body, housed in an electric furnace to produce and control the temperature thereof; a method for calibration of instruments for measuring temperature by telemetry; using a measurement subsystem for calibration of temperature measurement by telemetry, disposed opposite at least one said furnaces, consisting of a platform with longitudinal graduated scale as an indicator of distance, which is adapted to mount pattern equipment and the equipment to be calibrated; a PC, in which temperature readings of the reference ring system with thermal gradient of the cylindrical cavity of black body and, reference pattern equipment with traceability, are feed to obtain a temperature profile that allows, through a specialized mathematical calculation program based on comparisons, calibrate and/or characterize the temperature measuring instruments by telemetry.

主权项：1. A system for calibration and/or characterization of temperature measurement instruments by telemetry, characterized by comprising at least an electric furnace with temperature controller with digital ramp containing a cylindrical cavity of black body with temperature sensors, wherein said cylindrical cavity of black body comprises mechanically linked around the cavity entrance disc with thermal gradient, and comprises at least one concentric thermal diffuser metal ring, with at least two temperature sensors on its smooth back, inserted in, at least two broached holes, located horizontally with respect to the axial axis of the cylindrical cavity black body and equidistant from its center, inserted on both sides; it comprises a housing that protects and accommodates the cylindrical cavity of the black body, through brackets thermal insulated in an enclosure thermal insulation, positioning it, by means of guides, in the center of the housing and exposing it on the front side of the oven electric; generating a radial temperature profile staggered by heat loss by convection and radiation in each concentric thermal diffuser metal ring, to define temperature profiles with temperature gradient by the thermal contact of the disc with the cylindrical cavity of black body that is heated with an electric heater; wherein said electric furnace comprises a self-adjusting temperature controller device with digital ramp with a data acquisition system, where connect the temperature sensors of said concentric thermal diffuser metal rings, and that in turn said data acquisition system is connected to a PC comprising a specialized mathematical computation program that processes information to obtain the behavior of the electric oven; subsystem for positioning and measurement for calibration and/or characterization of equipment temperature measurement by telemetry disposed opposite said at least one electric furnace, consisting of a platform with longitudinal graduated scale as an indicator of distance, adapted to mount the pattern equipment and equipment to be calibrated, with means for centering and leveling the measuring standard and equipment to be calibrated to the center of the black body of the electric furnace equipment, with which is captured readings of stabilized temperature from measuring standard, equipment to be calibrated and the temperature of the electric furnace shown in the screen; and wherein the collected data is fed to the PC mentioned, along with temperature readings that define the thermal gradients of concentric thermal diffuser metal rings on the disk with thermal gradient and by the mathematical calculation program generates an average temperature, which is compared with standard pyrometer temperature and thus, the measurement error is determined, further mathematical calculations required to determine the estimated uncertainty associated with the measurement method; because through the disc with thermal gradient, comprising at least one concentric thermal diffuser metal ring, besides knowing the temperature of the cylindrical cavity of black body and traceability with reference to national or international standards through calibration standard pyrometer, It allows to know the behavior of the temperature along the thermal gradient disc; thereby obtaining a temperature profile that allows you to calibrate and/or characterize, by direct comparison, the temperature measuring instruments by telemetry.
