Bruel & Kjaer sensors are sensors that use laser technology for measurement. They consist of a laser, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference. The Bruel & Kjaer sensor detection principle detects magnetic losses caused by eddy currents generated on the surface of a conductor under the influence of an external magnetic field. An AC magnetic field is generated within the detection coil, and the eddy currents produced in the metallic object being detected are monitored.
