Detectors are essential industrial devices designed to identify, measure, or monitor specific conditions such as gas, smoke, motion, or radiation. They are widely used in safety systems, environmental monitoring, and process control across industries like manufacturing, oil & gas, and automation. Common types include gas detectors for leak prevention, flame detectors for fire safety, and proximity sensors for automated machinery. These devices ensure operational efficiency, regulatory compliance, and workplace safety by providing real-time alerts and precise data.
