Industrial Applications

1. Semiconductor Wafer Vacuum Gripper Monitoring

In semiconductor manufacturing, delicate silicon wafers are transported between processing stations using robotic arms equipped with vacuum grippers. This sensor is integrated into the pneumatic control system to monitor the vacuum pressure continuously, confirming that a wafer is securely acquired before the robot begins its high-speed transfer.

Problem Solved

Prevents the dropping and destruction of highly valuable, fragile silicon wafers during automated handling by instantly detecting vacuum loss or insufficient suction.

2. Low-Pressure Leak Testing for Medical Devices

During the production of sealed medical components like blood bags, catheters, or tubing sets, non-destructive leak testing is performed using low-pressure compressed air or inert gases. The sensor monitors the pressure decay over a specific time cycle to identify micro-leaks without over-pressurizing and damaging the delicate medical products.

Problem Solved

Identifies microscopic leaks in fragile medical products using low-pressure gas, ensuring product integrity and patient safety without causing stress-induced damage during testing.

3. Low-Force Pneumatic Clamping for Fragile Components

In automated assembly cells handling thin-walled electronics, glass enclosures, or delicate plastics, pneumatic cylinders are used to hold parts in place. Because these components are easily crushed, the actuation pressure must be kept exceptionally low. This sensor monitors the low positive pressure supplied to the clamping cylinder to ensure it remains strictly within safe operational limits.

Problem Solved

Prevents the crushing, scratching, or deformation of fragile components during automated clamping operations by precisely monitoring and limiting the applied pneumatic pressure.
