Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , the optical system in the device of the present invention is composed of a lens group lens 1 and an energy transmission fiber 2, wherein the diameter of the front end of the lens group lens 1 is 25mm, the field of view is 28°×40°, the coupling wavelength range is 350nm~2000nm, and the Y-shaped energy transmission fiber 2. The quartz fiber with a core of 600 μm is used, and the deviation of the two branches is less than 5%; the circuit system 3 consists of a photodetector, a preprocessing module, a preamplification module, an AD sampling module, a signal processing module, a display module, and a keyboard input modules and information interaction modules. The optical system and the circuit system are independent of each other. The entire circuit system can be placed in the electronic box, which can better avoid the interference of th...

Abstract

The invention discloses an optical fiber radiation thermometer based on a colorimetric method, and belongs to the field of high temperature measurement. The thermometer comprises an optical system and a circuit system, wherein lenses of a lens group are connected with a high-power Y-type power transmission optical fiber to form the optical system; the circuit system adopts signal dual-channel processing and comprises photoelectric detectors, a preprocessing module, a preamplifier, an AD sampling module, a signal processing module, a display module, a keyboard input module and an information interaction module. Signals are divided into two paths via the power transmission optical fiber and transmitted to the corresponding photoelectric detectors, optical signals are converted into current signals, the current signals are converted into voltage signals via the preprocessing module and the pre-amplification module, the signal processing module adopts a curve fitting algorithm for analysis, sampling signals are obtained, a corresponding temperature value is calculated through calibration, and difference setting is further improved through the interaction module. The optical fiber radiation thermometer structure based on the colorimetric method can be applied to measurement of a crystal furnace thermal field.

Description

technical field [0001] The invention relates to an instrument for measuring the thermal field of a crystal furnace, in particular to an optical fiber radiation thermometer based on a colorimetric method for measuring the thermal field of a crystal furnace. Background technique [0002] Contact measurement methods, especially thermocouples, are traditional measurement methods in the field of pyrometry. However, it has disadvantages such as poor corrosion resistance, short life, high consumption, high price, and the upper limit of temperature is mostly below 1800°C. [0003] Radiation pyrometers using non-contact methods are another common method in the field of pyrometry. The radiation thermometer calculates the corresponding temperature by means of non-contact measurement of the energy of infrared thermal radiation. The upper limit of measurement is not limited by the temperature resistance of the temperature sensing element, so there is no limit to the maximum measurable t...
