Abstract

The invention discloses a single wavelength temperature measuring system, relates to the field of wavelength temperature measuring systems, and aims to enable the single wavelength temperature measuring to be wide in measuring range, and high in response speed. The single wavelength temperature measuring system comprises a probe, a detector, a preamplifier, a thermostatic controller, a corrector, a linear element, a peak value recorder, a V / I converter, an A / D converter and a display; radiant heat energy collected by the probe is transmitted to the detector through optical fibers, the preamplifier amplifies a heat energy signal of the detector, then the heat energy signal is conveyed to the linear element and the peak value recorder through the corrector, and is conveyed to the V / I converter and the A / D converter after the peak value recorder records the peak value of the signal, and finally an actual temperature value is displayed on the display. The single wavelength temperature measuring system adopts a non-contact measurement mode to measure instant high temperature, and is high in response speed.

Description

technical field [0001] The invention relates to the field of wavelength temperature measurement systems, in particular to a single wavelength temperature measurement system. Background technique [0002] The use of optical fiber in temperature measurement is a new technology developed in recent years. The optical fiber temperature sensor uses a polymer temperature-sensitive material that matches the refractive index of the optical fiber to coat the outside of two fused optical fibers, so that light energy is input from one optical fiber to the reflective surface and output from the other optical fiber. A new type of temperature-sensitive material is affected by temperature, and its refractive index changes, so the output optical power is a function of temperature. Its physical essence is to use the characteristic parameters of the light waves transmitted in the optical fiber, such as amplitude, phase, polarization state, wavelength and mode, etc., which are sensitive to...
