Industrial Applications

1. Real-time Statistical Process Control (SPC) in CNC Machining Floors

Operators measure machined parts directly at the workstation and transmit raw dimensions over the 2.4 GHz band to central databases running MeasurLink software.

Problem Solved

Eliminates the labor-intensive and error-prone process of manually typing measurements, preventing transcription errors and keeping operators a safe distance from moving machinery.

2. On-Machine Part Inspection with Coolant Exposure

Integrates with Coolant-Proof micrometers to measure physical components while still inside the CNC machining enclosure. Paired with a waterproof connector (02AZF310), it maintains tool resistance to fluids.

Problem Solved

Conventional data cables are stiff, limit tool reach, and easily degrade or snap when exposed to cutting oil, chips, and high-frequency vibrations.

3. Multi-Gauge Ergonomic Assembly Checking Stations

Allows a single inspector utilizing multiple hand-held tools (such as micrometers and digital indicators) to maneuver freely around large assemblies, checking various part thicknesses and sending data sequentially.

Problem Solved

Eliminates physical workspace limits and safety hazards associated with multiple long cables crossing over large, heavy components during high-precision assembly checks.
