Abstract
The utility model relates to a temperature sensor with a thermometric range from 800 to 3000DEG C, which is composed of a high temperature lightwave transmitter, a cooling device, an optical condenser lens, a light conducting fiber and a photoelectric conversion device. The utility model has the advantages of broad application, high measuring precision, strong anti-interference capability, long service life, etc., and can easily form an industrial automatic control system.
Description
The utility model relates to a kind of temperature sensor, and particularly its thermometric upper limit reaches 3000 ℃ temperature sensor.
Be used for the higher temperature measured sensor in the industrial processes at present and mainly contain thermopair and optoelectronic series temperature instrumentation.Say occasionally that with regard to thermoelectricity it not only is subjected to medium character, the restriction of environment for use and use atmosphere, and also the thermometric upper limit also can't be above 2300 ℃; As for the photoelectric thermoscope table, though significant development and progress has been arranged in recent years, but owing to reaching, the different measuring accuracy that cause of various materials its light wave emissivity when the uniform temp do not require this situation to take on a new look, so its application also is restricted at all.
The purpose of this utility model will overcome above-mentioned defective exactly, reaches 3000 ℃ and the high temperature sensor of measuring accuracy for society provides a kind of its thermometric upper limit.
The technical scheme of cloth utility model is just like following: a kind of temperature sensor contains light transmitting fiber 4 and photoelectric conversion device 5, it also contains the high temperature light wave transmitter 1 by the exotic material processing and fabricating, cooling device 2 and optical concentration mirror 3, described high temperature light wave transmitter 1 has the end A that can satisfy optical concentration mirror 3 required light wave area coverages.
During concrete enforcement, can make high temperature light wave transmitter 1, and cooling device 2 is a heat eliminating medium with water with graphite.
During work, its high temperature light wave transmitter 1 of the utility model and end A with joined by the thermometric source, be that A end temperature equals by the thermometric source temperature, the light wave that this temperature produced (monochrome band 0.75～1.1um or double-colored wave band 0.75～1.1um, 0.95～1.1um) be emitted to optical concentration mirror 3 by end A, conduct to photoelectric conversion device 5 by light transmitting fiber 4 behind optically focused, the gained electric signal can supply secondary instrument displays temperature value, or realizes temperature automatically controlled for industrial automation control system.Cooling device 2 is to design for the temperature that reduces optical concentration mirror 3.Because the end A of high temperature light wave transmitter 1, by known exotic material processing and fabricating, so its emissivity and the gradient also are known, in view of this, the electric signal that this sensor produces is only promptly corresponding by the temperature in thermometric source with the temperature of the end A of high temperature light wave transmitter 1, and with irrelevant by the material in thermometric source.
In sum, the utility model can be used for measuring the temperature of unlike material Wen Yuan and needn't revise, and is that the adjustable type temperature sensor is exempted from a kind of universal scene; It also has temperature-measuring range wide (800～3000 ℃), and easy to use, advantages such as measuring accuracy is high, reaction velocity is fast, strong interference immunity, output electric signal continous-stable, long service life possess the wide development prospect.
The utility model also can with colorimetric pyrometer, the supporting use of automated optical pyrometer.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1. high temperature light wave sensor (strap end portion A), 2. cooling device, 3. optical concentration mirror, 4. light transmitting fiber, 5. photoelectric conversion device.
