German ALPAR METAL sensor ALPAR METAL model ALPAR METAL price

ALPAR METAL 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 detection principle of ALPAR METAL sensors involves detecting 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 detection is based on the effects of eddy currents produced in the metallic body of the target.
