Leakage Detection System

Leak detectors capture physical signal changes, such as pressure differentials, sound waves, or bubbles, generated by gas or liquid leaks through sensors. They are used to locate leakage points in sealed components like pipelines and containers, ensuring the proper operation of equipment in industries such as chemical and water supply.
Selection
Select the corresponding technical type based on the detection medium; pressure decay method is used for gases, while ultrasonic method is suitable for small leaks. Consider the sensitivity and compatibility with the detection environment; explosion-proof situations require certification. Refer to the measurement range and error margin, and make a comprehensive judgment by combining operational convenience and maintenance costs.

Articles

Sealing tester measures the pressure resistance and leakage of composite film bags.
This article introduces how to use a seal tester to evaluate the pressure resistance and leakage performance of composite film bags. The test primarily involves applying controlled pressure inside the packaging and observing pressure changes or leakage to assess the quality of the seal.
Positive pressure method seal tester evaluates packaging pressure resistance
This article introduces how the positive pressure method sealing tester evaluates the pressure resistance of packaging. The instrument simulates actual pressure conditions by injecting compressed air into the packaging and then monitors pressure changes to determine if there is any leakage.
Negative pressure method leak detector for testing vacuum packaging seal integrity
The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
Sealing Tester Measures Leak Points in Flexible Packaging Bags.
This article introduces how a seal tester detects air leak points in flexible packaging bags. It primarily identifies leaks through changes in pressure or vacuum, and the operation involves preparing samples, setting parameters, and conducting standardized testing.
Sheffield Smoothness Tester for Analyzing Paper Printing Surface
This article introduces how the Sheffield smoothness tester analyzes the printing surface of paper. The instrument quantifies paper smoothness by measuring the air leakage time, with a longer time indicating a smoother surface.
Negative Pressure Method Sealing Tester for Detecting Leakage in Food Packaging
The negative pressure method seal tester creates a pressure difference inside and outside the packaging by evacuating air to detect leaks in food packaging. If there is a leak in the packaging, water will enter the packaging or produce continuous bubbles under the pressure difference, thereby determining the seal integrity. The test requires controlling parameters such as vacuum level and time, and should be conducted in accordance with relevant standards.
Principle and Application of Vacuum Decay Leak Testing Equipment
The vacuum decay leak tester is a non-destructive detection device that quantitatively detects leaks by monitoring minute pressure changes in the test chamber after vacuum evacuation.
