Abstract

The invention discloses an in-situ passive temperature measurement method. The method comprises the following steps: preparing a plurality of groups of temperature sensing elements; calibrating the phase change temperature of the plurality of groups of temperature sensing elements; fixing the plurality of groups of temperature sensing elements on the surface of a to-be-measured target; judging the temperature of the to-be-measured target according to the phase change conditions of the plurality of groups of temperature sensing elements; the method can solve the problem of temperature measurement in a high-temperature, narrow and closed space, and has the advantages of simple structure installation, high shock resistance, low cost, in-situ measurement and the like.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to an in-situ passive temperature measurement method. Background technique [0002] Metal smelting, petrochemical, aerospace and other engineering applications often require ultra-high temperature temperature measurement at around 2500 °C to monitor, manage, design, and manufacture industrial processes. In practical engineering applications, it is often necessary to measure temperature in a narrow and airtight environment. At present, the existing contact temperature measurement method faces problems such as the upper limit of temperature measurement is limited by the melting point of the material itself, the condition of no lead wire in a small space, the installation and interpretation are complicated, and in-situ measurement is impossible. ; The non-contact temperature measurement method faces problems such as difficulty in providing sufficient windows in a confin...
