Industrial Applications

1. Cleanroom Pick-and-Place Vacuum and Pressure Gripping Verification

Utilized in semiconductor or precision electronics manufacturing, this sensor monitors the air pressure applied to suction grippers that use alternating vacuum for lifting and positive pressure blow-off for releasing delicate components.

Problem Solved

Prevents dropped components and mishandling by actively verifying vacuum thresholds during the grip phase and positive pressure peaks during the release phase, all within a particulate-sensitive environment.

2. Automated Leak Testing in Pneumatic Sub-assemblies

Integrated into end-of-line quality control test rigs, the sensor measures pressure decay in sealed pneumatic chambers and valve blocks after they are pressurized with compressed air to test for seal integrity.

Problem Solved

Identifies micro-leaks and faulty seals in manufactured sub-assemblies by reliably detecting minute pressure drops below a critical threshold using high-precision repetition monitoring.

3. Inert Gas Blanketing Pressure Control for Packaging

Deployed in pharmaceutical or sensitive packaging systems to monitor the continuous supply of nitrogen or argon gas used to purge oxygen from containers before final sealing.

Problem Solved

Ensures the packaging process neither starves from insufficient inert gas supply nor suffers from over-pressurization blowouts, maintaining consistent gas flow by utilizing specific high and low logic bounds.
