In today's production factories, depending on the product, a "leak test" for all items is required to maintain high manufacturing quality. However, the traditional "submersion visual inspection" is labor-intensive and makes quantifying the inspection difficult. The leak tester is a device that applies pressure (or vacuum) to finished products and parts that require inspection, detecting and measuring pressure changes with a high-sensitivity differential pressure sensor. By electrically detecting "leaks," it enables quantification and automation of the inspection process. For more details, please download the catalog.

In today's production factories, depending on the product, a "leak test" for all items is required to maintain high manufacturing quality. However, the conventional "submersion visual inspection" is labor-intensive and makes quantifying the inspection difficult. A leak tester is a device that applies pressure (or vacuum) to finished products or parts that need inspection and detects and measures pressure changes using a highly sensitive differential pressure sensor. Since it detects "leaks" electrically, it allows for quantification and automation of the inspection process. For more details, please download the catalog.

It was very difficult to set the workpiece using a robot in a leak test where a clamping mechanism is essential to seal the workpiece. However, by using a six-axis robot, we were able to gain a certain degree of freedom in movement, which allowed us to resolve the issue. Additionally, for the loading and unloading, we use air cylinders to keep the slide end in its original position, which results in a design that minimizes displacement in the Y (X) axis. We are moving away from conventional semi-automatic machines (manual workpiece setting) and achieving online automation.

The NLT-130 is a direct pressure air leak tester designed with essential functions prioritized for cost-effectiveness. - Recommended for those who want to implement it as cheaply as possible. - Currently conducting all direct pressure air leak tests manually. It features automatic functions from pressurization to measurement and OK/NG judgment after pressing the start button. The displayed value only shows the pressure within the measurement volume (including piping). *No zero reset during measurement transition. 【Features】 ■ Thorough cost performance ■ No difficult adjustments required without a master tank ■ Compact design for easy operation

We would like to introduce a case in the water and gas piping joint industry where a leak tester enabled stable measurements and reduced measurement time. As background, stable measurements could not be achieved due to the temperature difference between the workpiece and the master. Additionally, it was necessary to change the master volume depending on the workpiece, making changeovers quite challenging. By using a secondary measurement method, we achieved stable measurements with minimal temperature influence. As a result, it became possible to shorten changeover time and reduce measurement time through multiple part handling. [Case Overview] ■ Background - Stable measurements could not be achieved due to the temperature difference between the workpiece and the master. - Changeovers were difficult as it was necessary to change the master volume depending on the workpiece. ■ Results - Achieved stable measurements with minimal temperature influence through a secondary measurement method. - Enabled reduction of changeover time and measurement time through multiple part handling. *For more details, please download the PDF or feel free to contact us.
