This is one of the largest application markets for sensors, primarily used to achieve automated production and smart manufacturing.

Process Control: Temperature, pressure, flow, and level sensors are used to monitor the fluid, gas, and mechanical conditions on production lines.

Motion Control: Photoelectric sensors and proximity switches are used to detect object positions, count objects, and prevent collisions.

Predictive Maintenance: Vibration sensors and acoustic sensors are used to monitor the health of motors and bearings, providing early warnings of malfunctions.

Quality Inspection: Vision sensors (machine vision) are used to detect surface defects, measure dimensions, and identify barcodes.
