Technical details and manufacturing context for Grounding Verification Sensor

Definition
A critical component within Safety Interlock Systems that continuously monitors and confirms the integrity of electrical grounding connections. It prevents equipment operation when grounding is insufficient or compromised, protecting against electrical shock hazards and ensuring compliance with safety standards.
Working Principle
The sensor measures electrical resistance between equipment chassis and earth ground. It compares this measurement against preset safety thresholds. If resistance exceeds safe limits (indicating poor grounding), it sends a signal to the interlock system to prevent equipment activation or trigger shutdown procedures.
