Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a device for high-precision real-time automatic detection of salt spray deposition rate at multiple measurement points. Background Technology

[0002] Salt spray deposition rate is a crucial indicator in salt spray environmental simulation tests, significantly impacting the test results. Traditional methods for detecting salt spray deposition rate rely on manual monitoring, resulting in long monitoring intervals. For example, GJB150.11A-2009 specifies that the salt spray deposition rate should be measured at least once every 24 hours throughout the spraying period. This method only reflects a 24-hour average, potentially failing to detect blockages in pipes or multiple nozzles, which can significantly affect test results, especially in large walk-in salt spray test chambers. Therefore, although most salt spray testing equipment generally exhibits good reproducibility in its salt spray deposition rate indicator, real-time automatic detection is essential.

[0003] Existing manual detection methods are time-consuming, labor-intensive, and have low accuracy. Because the test chamber is filled with salt spray, the testers may knock over and break the measuring cylinder containing the salt solution, making it impossible to obtain test data. The salt spray test chamber is filled with salt spray particles with diameters ranging from a few micrometers to hundreds of micrometers. These salt spray particles have a strong irritant effect on the lung mucosa, skin, and eyes, posing a serious threat to the health of the testers. Therefore, we propose a device for high-precision real-time automatic detection of salt spray deposition rate at multiple measurement points. Utility Model Content
