Description
The utility model relates to and belongs to a kind of measurement mechanism, a kind of specifically novel optical fiber high temperature measurement device.
Detection in fields such as metallurgy, chemical industry, the energy, building materials to temperature has very high requirement.Still mainly use the temperature sensor of making by noble-metal thermocouples such as platinum, rhodiums at present in the commercial production.But the thermopair high-temperature oxidation resistance is poor, and long-term use not only can produce bigger error, and when in some have the environment of chemical gas, working, can be corroded, embrittlement, serviceable life sharply shorten, and need change thermopair continually.So not only consume a large amount of precious metals, even more serious is that influence is produced.In many special bodies of heater,,, make temperature detection to carry out simultaneously because the anti-electromagnetic interference capability of thermopair is poor as dielectric heating oven, microwave oven.
The purpose of this utility model is the above-mentioned deficiency at the thermocouple temperature measurement instrument, utilizes the blackbody radiation principle, and the probe that adopts blackbody chamber, optical fiber to make carries out thermometric a kind of novel optical fiber high temperature measurement device.
The purpose of this utility model realizes in the following manner: a kind of novel optical fiber high temperature measurement device; it is characterized in that described device is made up of metal ceramic tube, protection sleeve, ceramic blackbody chamber, fibre-optical probe and Transmission Fibers; metal ceramic tube is connected with protection sleeve; blackbody chamber is contained in the metal ceramic tube; fibre-optical probe is contained in the protection sleeve; fibre-optical probe one end is adjacent with blackbody chamber, and the other end links to each other with Transmission Fibers in stretching into protection sleeve.
On the described metal ceramic tube mounting flange is housed.
The front end of described fibre-optical probe can be provided with lens.
Principle of work of the present utility model is: the optical fibre high temp measurement mechanism is installed on the high temperature furnace and sealing (for pressure vessel) with mounting flange, metal ceramic tube can be isolated in the stove foreign material and be protected ceramic blackbody chamber.The pottery blackbody chamber is experienced the temperature variation of high temp objects and is launched radiation light-wave, and scioptics, fibre-optical probe receive radiation light-wave and transferred signals in the optical information processing device by Transmission Fibers and analyze, thereby draw measured temperature.
The black chamber of stopping of pottery of the present utility model, be meant to plate the black matrix material on the ceramic pipe inwall, it has good physics, chemical property, and is high temperature resistant, anticorrosive, especially valuable is that it has highly stable emissivity, and this is for very important with the radiation method thermometric.The utility model adopts the optical sensing mode, and anti-electromagnetic interference capability is strong, but and the signal teletransmission, to compare with the noble-metal thermocouple temperature measurer, the utility model cost is low, long service life.The utility model temperature measurement range is 700 ℃-1600 ℃, and measuring accuracy is 5 ‰.Can be widely used in the industries such as metallurgy, chemical industry.
The utility model content is described in detail in detail with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation
