Description

The optical fiber type temperature measurer that is used for heat generator

The utility model relates to the design and fabrication technology field of temperature measurer.

At present, the heat generator thermometric mainly adopts thermopair, because temperature fluctuates up and down in the stove; thermopair and protection tube can produce the temperature vibration phenomenon; because the thermopair life-span itself is limited, and therefore damage is more frequent, this not only influences thermometric work simultaneously; be unfavorable for continuous temperature control; and, increase maintenance capacity because the thermopair price is higher, and invisible increase has added cost; the consistance of thermopair itself is poor, the relative uniformity of measured temperature before and after also influence is changed.

The purpose of this utility model is a large amount of consumption of effectively stopping the thermometric device, reaches the thermometric consistance, and temperature survey is used for the optical fiber type temperature measurer of heat generator accurately.

The purpose of this utility model is achieved in that it is made of temperature measuring head, Prism spectroscope, photoelectric sensor, preposition amplification, analog to digital conversion, single-chip data disposal system, digital-to-analog conversion and output and power circuit.Dress principal goods mirror in the temperature measuring head shell; graticule; eyepiece; shell upper is a light transmitting fiber; outer casing underpart is peeped the coaxial flange of pipe with protection and is connected; the light transmitting fiber other end leads to the Prism spectroscope (patent No.: 97222832.2); protection from be contained in heat generator is peeped pipe light signal in the stove is taken out by the principal goods mirror; graticule is to light transmitting fiber; the light transmitting fiber other end leads to Prism spectroscope; the chromatogram light wave of Prism spectroscope output receives and the computing of single-chip data disposal system by photoelectric sensor; temperature is so just measured in output and temperature corresponding simulating amount or digital quantity.

The utility model has the advantages that rational in infrastructure, easy for installation, stable performance, with the thermocouple temperature measurement ratio, greatly reduce working strength of workers, the saving funds are not subjected to environmental interference.By light transmitting fiber the quick bamboo telegraph of light signal is come out, reach the accuracy of thermometric.

Below in conjunction with drawings and Examples the utility model is elaborated.

Figure is the utility model temperature measuring head structural representation.

This optical fiber type temperature measurer that is used for heat generator is made of temperature measuring head, Prism spectroscope, photoelectric sensor, preposition amplification, analog to digital conversion, single-chip data disposal system, digital-to-analog conversion and output and power circuit.Temperature measuring head shell 6 is that light transmitting fiber 1, outer casing underpart are peeped pipe 9 coaxial flanges 8 with protection and connected with built-in protective glass 7, principal goods mirror 5, graticule 2, eyepiece 4, eyepiece cover glass 3, shell upper; the light transmitting fiber other end leads to Prism spectroscope; the chromatogram light wave of Prism spectroscope output receives and the computing of single-chip data disposal system by photoelectric sensor, output and temperature corresponding simulating amount or digital quantity.Realize the purpose of thermometric.
