The invention discloses a blackbody cavity sensor capable of continuously measuring temperature, and relates to the technical field of temperature detection equipment. The device comprises a front endhead; one end of the front end head is bonded with a black body cavity pipe; one end of the front end far away from the blackbody cavity pipe is in threaded connection with a connecting cylinder; andan end, away from the front end, of the connecting cylinder is in threaded connection with a rear end head. Two semi-annular grooves communicated with an annular groove are formed in a peripheral side surface of the front end head; a first semiconductor device and a second semiconductor device are respectively arranged in the two semi-annular grooves; and an annular vacuum cavity is formed in theend, away from the annular groove, of the front end. According to the invention, the first semiconductor device and the second semiconductor device are powered on to transfer high-temperature heat inthe blackbody cavity pipe; and meanwhile, the annular vacuum cavity isolates the temperature between the front end head and the connecting cylinder, so that the normal use of the connecting cylinderand the rear end head is ensured, the service life of the sensor is prolonged, and the practicability is relatively high.
Description
technical field [0001] The invention belongs to the technical field of temperature detection, in particular to a blackbody cavity sensor capable of continuous temperature measurement. Background technique [0002] In metallurgy, chemical industry, energy, building materials and other industrial fields, the accurate and rapid measurement of high temperature is of great significance. Black body cavity sensors are in direct contact with a heat source and measure the temperature of the fluid and its interior. At the same time, it uses quartz multimode optical fiber to transmit the temperature signal to a place far away from the heat source for processing and display, avoiding high temperature working environment and electromagnetic interference. [0003] The existing blackbody cavity has a high heat dissipation rate and a very slow heat dissipation rate. After measuring the temperature of the high-temperature fluid, it needs to wait for a long time to cool the blackbody cavity,...
