Metal Detector

 Industry leading detection

Metal detectors look for fluctuations with magnetic fields when product passes through the detector head. Since the magnetic fields are affected by external sources such as floor vibration and inverters from nearby machines, a metal detector must be designed to handle these challenges. With this in mind, Anritsu's detection heads were designed to provide high sensitivity without sacrificing repeatability and reliability.

The detection head is highly resistant to external effects, accurately detecting even slight fluctuations.

Since metals respond differently to different magnetic field frequencies, it is difficult for conventional single frequency systems to detect both ferrous and non-ferrous metals. Anritsu has patented a dual-frequncy inspection system, which automatically determines the best frequencies to maximize sensitivity for both ferrous metals simultaneously. Stainless steel fragments dropped from a production equipment can be also detected.

HIS (High Sensitivity) setting automatically analyzes product and contaminant properties and sets detection limits precisely for optimal contaminant detection.
