From Joining Technologies / Laser Joining Technology

Sensors are devices that monitor changes or variations in an object or process relative to a reference standard. Depending on their intended function, they can recognize changes in weight, vibration, motion, pressure, color, heat, light, magnetism or chemistry. They may be part of a system controlling a manufacturing process, activating
