Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensor calibration and provides a bracket for calibrating the temperature and test angle of an infrared temperature sensor. Background Art

[0002] Infrared temperature sensor is a kind of sensor widely used in many fields. Its main feature is to measure temperature by receiving infrared radiation from objects. It has the advantages of non-contact, fast response and high precision. Infrared temperature sensor is widely used in many fields such as medical field, industrial field, thermal control, space technology, etc. Regular calibration and maintenance of infrared temperature sensor is also an important measure to ensure its long-term stable operation and accurate measurement.

[0003] First of all, calibration can ensure the measurement accuracy of infrared temperature sensors. Since infrared temperature sensors measure temperature by receiving infrared radiation from objects, their measurement accuracy will be affected by many factors, such as ambient temperature, surface characteristics of objects, etc. Through regular calibration, these influencing factors can be eliminated, making the sensor's measurement value more accurate, thus meeting the needs of practical applications.

[0004] Secondly, calibration helps improve the reliability of infrared temperature sensors. Since the sensor may be affected by factors such as wear and aging during use, its performance may change. Through calibration, these problems can be discovered and solved in time to ensure that the sensor can work stably for a long time.

[0005] In addition, infrared temperature sensor calibration is also an important means to ensure the stability of industrial production processes. In the fields of industrial automation, thermal control, etc., infrared temperature sensors are widely used in various temperature monitoring and control systems. If the sensor's measurement value is inaccurate, it may cause deviations in the production process and even cause safety accidents. Therefore, regular calibration of infrared temperature sensors is of great significance to ensure the stability and safety of industrial production.

[0006] Finally, calibration can also help improve the adaptability of infrared temperature sensors in different application scenarios. Since different application scenarios have different requirements for temperature measurement, sensors need to be calibrated specifically to meet specific needs. Through calibration, infrared temperature sensors can maintain stable performance in various complex environments, thereby better serving practical applications.

[0007] In summary, infrared temperature sensor calibration is of great significance in ensuring measurement accuracy, improving reliability, ensuring industrial production stability and improving adaptability. Therefore, in practical applications, infrared temperature sensors should be calibrated regularly to ensure the stability and reliability of their performance.

[0008] At present, infrared temperature sensors are generally disassembled and sent to the laboratory for calibration by measuring the temperature of a standard blackbody radiation furnace. Infrared temperature sensors, especially those used in industrial production applications, are installed in fixed positions. Disassembly and calibration can easily lead to damage, and customers' demand for online detection of infrared temperature sensors is becoming increasingly prominent. At the same time, the temperature measurement angle of the infrared temperature sensor also affects the accuracy of the temperature measurement. Since infrared light is not visible light, the traditional method of measuring the angle of the temperature sensor housing is prone to measurement deviations.

[0009] Therefore, it is particularly important to have an infrared temperature sensor temperature and angle calibration bracket that can adjust the angle. Utility Model Content
