Cleanroom 'Transparent Killer' Terminator: EST-200N's Practical Application in Biopharmaceuticals
Automated testing of transparent reagent glass bottles has always been a pain point in precision manufacturing fields such as biomedicine and chemical analysis.
Automated testing of transparent reagent glass bottles has always been a pain point in precision manufacturing fields such as biomedicine and chemical analysis. Traditional photoelectric sensors are prone to false positives and false negatives due to the low reflectivity of transparent materials, and the interference of background light exacerbates the instability of detection.
To solve the above problems, Meiji has developed the EST series sensors specifically for detecting transparent materials. In this issue, Xiao Ming will share a practical case of EST-200 in the automated detection of transparent reagent glass bottles in a pharmaceutical company.
On site testing faces three challenges:
1. Low contrast: The wall thickness of the glass bottle is only 2mm, and the transmittance of visible light is as high as 92%. Traditional reflective sensors are difficult to trigger signals due to insufficient light intensity attenuation;
2. Background light interference: The white sunlight lamp (illuminance ≥ 3000lux) forms a mirror reflection on the surface of the bottle, causing the sensor to misjudge it as a "bottle" state;
3. Detection distance limitation: The production line requires sensors to accurately identify bottle bodies within a distance of 100mm, while conventional sensors often have an effective detection range below 50mm.
Sensor selection
Recommend using Akusense transparent material dedicated sensor EST series
Detection distance: adjustable from 0-200mm
Response time: ≤ 0.5ms, meeting high-speed sorting requirements
Protection design: IP67 level sealing structure effectively resists corrosion from liquid vapor
Working temperature: -25 ℃ to+55 ℃, meeting the requirements of clean workshop
Anti light interference: Designed to resist strong light, the EST-200N operates stably under incandescent lamp illumination of ≤ 3000Lux. Through infrared filtering technology and dynamic threshold algorithm, it automatically filters out ambient light interference. Actual test data shows that in direct sunlight (10000Lux) environment, the sensor false alarm rate is less than 0.1%
The Akusense EST-200N photoelectric sensor demonstrates excellent stability in transparent reagent glass bottle detection by combining the principle of retro reflection with dynamic anti-interference technology. Its 0.5ms fast response and 99.92% detection accuracy not only meet the dual requirements of efficiency and reliability for pharmaceutical production lines, but also provide a replicable technical solution for automated detection of similar transparent materials.
