Description

Technical Field

[0001] The utility model belongs to the technical field of sensor detection devices, and in particular relates to a detection device of a non-contact infrared temperature measurement sensor. Background Art

[0002] A non-contact infrared temperature sensor is a sensor specifically used to measure the surface temperature of a target object. Unlike traditional contact temperature sensors, a non-contact infrared temperature sensor determines the surface temperature of an object by receiving infrared radiation emitted by the target object without actually contacting the target object. The working principle of a non-contact infrared temperature sensor is based on the Stefan-Boltzmann law, that is, the surface temperature of an object is proportional to the intensity of the infrared radiation it radiates. When the non-contact infrared temperature sensor receives infrared radiation emitted by the target object, the sensor converts these radiations into temperature values, thereby measuring the temperature of the target object. Non-contact infrared temperature sensors have the characteristics of fast, non-destructive, and long-distance measurement. They are suitable for temperature monitoring in situations where physical contact needs to be avoided or measurement is inconvenient, such as in industrial production lines, healthcare, building monitoring, food processing and other fields. Through non-contact infrared temperature sensors, accurate measurement and monitoring of the temperature of the target object can be achieved, thereby helping to achieve automated control and temperature management.

[0003] The existing detection method for non-contact infrared temperature sensors is to place the non-contact infrared temperature sensor in a constant temperature and humidity chamber, and compare the temperature value measured by the sensor with the temperature provided by the constant temperature and humidity chamber to evaluate the precision and accuracy of the sensor. This method cannot quickly adjust the temperature, resulting in a long time to detect non-contact infrared temperature sensors under extreme temperature differences, and the detection results are not intuitive enough.

[0004] Therefore, how to enable the detection device to have the function of quickly adjusting the temperature and the function of intuitively displaying the detection results is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Therefore, the power supply is first connected to the conductive cover, and then the non-contact infrared temperature measurement sensor is turned on through the probes contacting the conductive seat.

[0011] Furthermore, it also includes a switching power supply, which is electrically connected to the temperature controller, the test mounting position and the display screen, and converts the input power supply into a stable output voltage and current through the switching power supply, and ensures the stability and reliability of the output power supply.

[0012] Furthermore, the housing comprises a shell and a shell cover, the temperature controller, the temperature plate and the standard temperature measuring component are arranged in the shell, and the test installation position is arranged on the shell cover.
