Abstract

The invention discloses a surface emissivity measurement system, and relates to the technical field of emissivity measurement. The surface emissivity measurement system comprises an infrared temperature measurement detector, a contact-type thermodynamic temperature sensor, a signal processing circuit and a computer; the contact-type thermodynamic temperature sensor is arranged on the surface of a target object to be measured, and transmits a surface thermodynamic temperature signal of the target object to be measured to the signal processing circuit; the infrared temperature measurement detector is arranged on the upper side of the target object to be measured, and transmits a radiation temperature signal of the surface of the target object to be measured to the signal processing circuit after the radiation temperature signal is processed; the signal processing circuit conditions the received signal, and then transmits the conditioned signal to the computer; the computer is used for performing calculating processing, data display and storage on the emissivity of the surface of the target object to the measured. The surface emissivity measurement system has the beneficial effects that the system is simple in structure and easy to install and maintain; a target material does not need to be sampled; the measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of emissivity measurement, in particular to a surface emissivity measurement system. Background technique [0002] With the development of infrared technology, emissivity measurement technology has been used more and more in the fields of infrared stealth design, energy-saving material testing and solar power generation. The techniques currently used for emissivity measurement include calorimetry, reflectivity method and multi-wavelength method: calorimetry has high measurement accuracy and can continuously measure the emissivity of samples in a wide temperature range, but it needs to be The target material is sampled and the equipment is relatively complicated; the reflectance method can achieve the effect of non-contact measurement of emissivity, but it has high requirements for active light sources, and can only measure the target spectral emissivity within the wavelength range of the light source, which ...
