Programmable high and low temperature wet heat alternating test machine five major performance and temperature measurement points
The Programmable High and Low Temperature Wet Heat Alternating Test Machine is a critical tool used in environmental testing to simulate real-world conditions. Its five key performance aspects and temperature measurement points are essential for ensuring accurate and reliable test results. To evaluate the machine's performance, it must be conducted under standard atmospheric conditions. However, external factors can influence the internal environment of the test chamber, so several considerations must be taken into account: 1. The surrounding environment should meet the requirements outlined in GB/T 2421. 2. The test chamber should not be exposed to direct sunlight. 3. It should be placed away from sources of electromagnetic interference. 4. The machine must be installed on a level surface. 5. The location should be free from mechanical or acoustic vibrations. Note: Always follow the manufacturer’s guidelines regarding power supply and environmental conditions. Any abnormal situations during testing should be documented thoroughly. Temperature Measurement System: The accuracy of the temperature measurement system is determined through calibration. Typically, resistive sensors or thermocouples are used. The sensor response time in air should be between 10 and 40 seconds, while the entire system should respond in less than 40 seconds to ensure timely and precise readings. Test Load Considerations: All measurements are performed in an unloaded test chamber. If the chamber cannot be completely empty, this should be recorded. When testing with a load—whether it generates heat or not—the characteristics of the sample (such as weight, quantity, placement density, and arrangement) can significantly affect the test results. These factors should be carefully noted during the process. Sensor Placement: At least nine temperature sensors should be positioned at each corner and the center of the working space. For machines larger than 2000L, additional sensors should be placed directly in front of each wall. The total number of sensors should be no less than 15. The placement should not interfere with the natural temperature distribution and must be capable of accurately recording the actual temperature achieved during testing. Temperature Performance Evaluation: Once the test chamber reaches stability, the actual temperature, temperature fluctuations, and temperature gradients within the workspace should be confirmed using the measurement system. The uncertainty of the temperature measurement system must also be considered to ensure the validity of the results.
