Industrial Applications

1. Lithium-Ion Battery Cell Handling and Assembly

Utilizing the SPAN-B pressure sensor in a robotic pick-and-place system for handling sensitive Li-ion battery pouches. The sensor simultaneously monitors the vacuum needed for the suction cup grip (-1 bar) and the positive pneumatic pressure (up to 10 bar) for the actuator release mechanism. The F1a compliance ensures that trace heavy metals do not contaminate the sensitive battery cell chemistry.

Problem Solved

Prevents chemical contamination in battery assembly by utilizing Cu/Zn/Ni-reduced components, while reliably confirming part presence via vacuum monitoring and avoiding accidental cell drops using precise threshold comparators.

2. Semiconductor Wafer Processing Inert Gas Control

Deployed in a Class 4 cleanroom semiconductor processing station to monitor the supply of inert shielding gases. The sensor uses a programmable window comparator function to ensure the gas supply remains precisely within optimal parameters. The high repetition accuracy of 0.3 %FS ensures consistent and repeatable processing conditions without risk of contamination.

Problem Solved

Ensures defect-free semiconductor wafer processing by detecting micro-fluctuations in inert gas delivery. The cleanroom-certified sensor prevents particle contamination and triggers an instant switching output if gas pressure exits the defined tolerance window.

3. Automated Packaging Line Pneumatic Fault Detection

Integrated directly into an automated packaging line's pneumatic control manifold utilizing standard 4 mm O.D. pneumatic tubing. Maintenance operators utilize the PIN-protected teach-in functions via the illuminated LCD to set strict high/low threshold values. This provides immediate, tamper-proof visual and electronic feedback on the pneumatic line's status.

Problem Solved

Eliminates unauthorized or accidental adjustments to critical pneumatic pressure thresholds in high-throughput packaging environments, reducing machine downtime and avoiding scrap material caused by under-pressurized or over-pressurized pneumatic actuators.
