The differential pressure method is currently known as the most popular airtight waterproof testing device. The differential pressure method is also referred to as the "volume detection method" because when a constant pressure is applied within a constant volume, the pressure changes due to the volume of the pressurized space changing as air flows into the workpiece. When used as an actual field device, the following factors can appear as judgment noise: (1) Variability in the space (volume) of the capsule when the workpiece is inserted (it is desirable to keep this as small as possible). (2) Variability in the shape (volume) of the workpiece. (3) Changes in the shape (volume) of the workpiece due to pressurization. (4) Pressure changes due to variations in the temperature of the workpiece and its surroundings. (5) Changes in the volume of the pneumatic circuit. While quantitative judgment (defining the leakage amount numerically for pass/fail determination) is possible, these noises can potentially lead to misjudgment. *WPC is not affected by these judgment noises.

Basic Structure of Strain Detection Method (1) Prepare a pressurized capsule for the workpiece. (2) Place the workpiece inside the capsule. (3) Pressurize the inside of the capsule. (4) Measure the strain on the surface of the workpiece. (5) Close the valve at a desired pressure and stop the pressurization. (6) Measure the change in strain on the surface of the workpiece. The judgment is made as shown in the graph of the image during the above operations. Explanation of the graph: (1)(2) When the area around the workpiece is pressurized, the surface of the workpiece deforms (dents) due to the pressure difference between the inside and outside. (3) If there is a large leak, this pressure difference will not occur or will equalize quickly, resulting in no deformation or a rapid return to its original shape. (4) If no large leak is detected, the change in strain is measured at a constant pressure to perform small leak detection. (5) If there is a small leak, the pressure difference between the internal and external pressures gradually decreases, causing the strain to recover. (6) If no small leak is detected, the strain at a constant pressure stabilizes and does not recover.
