Technical Note | MDI Leak Detection Test

This video demonstrates an industrial leak detection sensor test using MDI and the YHSP-SA Electronic Leak Point Sensor. The test verifies no false alarms in water, reliable organic solvent detection, and successful alarm activation in less than 20 seconds.

MDI Leak Detection Test Using the YHSP-SA Electronic Leak Point Sensor

Yoohantech continuously conducts leak detection performance tests using real industrial chemicals to verify sensor reliability, response characteristics, and field performance.

This test evaluates the leak detection capability of the YHSP-SA Electronic Leak Point Sensor using MDI (Methylene Diphenyl Diisocyanate), a widely used industrial chemical.

Test Overview

• Test Material: MDI (Methylene Diphenyl Diisocyanate)
• Sensor Model: YHSP-SA
• Initial Sensor Value: 1.0436
• Alarm Threshold: 1.0536
• Detection Time: Less Than 20 Seconds
• Test Purpose: Verification of MDI leak detection performance

Water Response Verification

Before testing the MDI sample, the sensor was immersed in water for approximately one minute to verify whether any false alarm would occur.

The sensor showed no response and no alarm activation during the water test.

This confirms the sensor's ability to distinguish water from target chemicals and prevent false alarms caused by moisture, condensation, or rainwater.

MDI Leak Detection Test

After removing moisture from the sensor surface, the sensor was immersed in the MDI sample and the response time was measured under the same conditions as the water test.

The sensor successfully responded to the MDI sample and activated the alarm in less than 20 seconds.

The measured value increased from the initial reading of 1.0436 and reached the preset alarm threshold of 1.0536, confirming reliable leak detection performance.

Test Results

• Water: No Response After One Minute
• MDI: Detected in Less Than 20 Seconds
• False Alarms: None
• Alarm Activation: Successful

Key Features of the YHSP-SA Leak Detection Sensor

• Optimized for Organic Solvents
• No False Alarms in Water
• Fast Response Performance
• Chemical-Family-Specific Detection
• Reusable Sensor Design
• Reduced Maintenance Costs
• Suitable for Industrial Chemical Leak Detection Applications

Conclusion

This test confirms that the YHSP-SA Electronic Leak Point Sensor can reliably detect MDI while maintaining immunity to water-induced false alarms.

The successful detection of MDI within less than 20 seconds demonstrates the sensor's suitability for industrial leak detection, chemical spill monitoring, and process safety applications.
