Industrial Applications

1. Lithium-Ion Battery Cell Handling and Vacuum Gripping

Utilizing the SPAN pressure sensor to monitor vacuum and positive pressure in pneumatic pick-and-place systems used for assembling delicate battery cells. The sensor checks vacuum levels down to -1 bar to ensure secure grip and monitors actuator pressure up to 10 bar.

Problem Solved

Standard automation sensors risk contaminating sensitive battery chemistry with heavy metals. This application leverages the sensor's F1a suitability (reduced Cu/Zn/Ni values) to ensure zero contamination while accurately verifying gripping force.

2. Semiconductor Wafer Processing Pneumatic Control

Deploying the SPAN sensor in an ISO Class 4 cleanroom to monitor the supply of compressed air and inert gases to pneumatic end-effectors handling semiconductor wafers. It utilizes the window comparator function to trigger an alarm if gas pressure fluctuates outside safe operating bounds.

Problem Solved

Eliminates particulate and outgassing contamination risks in highly sensitive semiconductor cleanrooms while providing local, high-visibility monitoring through its programmable illuminated LCD.

3. Automated Fixture Clamping and Local Leak Detection

Integrating the pressure sensor into an automated assembly station using its 4mm O.D. push-in tubing connection. The sensor is configured via its teach-in display with a PIN code to prevent unauthorized tampering of the set clamping pressure thresholds.

Problem Solved

Prevents manufacturing defects caused by under-pressurized pneumatic clamps or minor system leaks by sending an immediate max 80 mA NPN/PNP switching signal to the PLC if the relative pressure drops below the threshold.
