Description

Technical Field

[0001] The utility model relates to the field of sensor calibration, in particular to a temperature box for temperature sensor calibration. Background Art

[0002] As an indispensable part of modern industry and technology, temperature sensors play an important role in measuring and monitoring the temperature of objects or environments. Temperature sensors can convert the physical quantity of temperature into electrical signals or other forms of output signals, thereby achieving accurate measurement, real-time monitoring and effective control of temperature. Whether on a busy industrial production line, in precision equipment in a scientific research laboratory, or in the outdoor environment of an environmental monitoring station, temperature sensors play a vital role in ensuring the stable operation and safety of the system.

[0003] Before being put into use, temperature sensors must undergo a rigorous calibration process to ensure the accuracy and reliability of their measurement results. Among them, calibration in extreme high or low temperature environments is a common and effective method. This is because the performance of temperature sensors tends to change significantly under extreme temperature conditions, and a temperature chamber is a common device for calibrating temperature sensors. A temperature chamber is a box that can provide a stable and accurate temperature environment. By setting the temperature parameters of the temperature chamber, we can create a known temperature environment for the temperature sensor inside it, so as to compare and calibrate with the output of the temperature sensor.

[0004] However, existing temperature chamber designs often have some limitations. For example, most temperature chambers use a method of placing a slide plate at the bottom, placing the temperature sensor to be calibrated on the slide plate, and then closing the chamber door to form a closed calibration environment. Although this design is simple and practical, it has the problem of low space utilization. Since the slide plate can only be placed at the bottom of the chamber, the upper space of the chamber is often not effectively utilized, which to a certain extent limits the number of slide plates placed, thereby affecting the efficiency of the calibration process.
