The working frequency of the needle detector depends on different products.

The needle detection technology has reached a very perfect level, and the needle detection machine truly eliminates metal contamination. why would you said this? In fact, in the past, due to technical reasons, it was often impossible to guarantee the stable operation of the detector, so false alarms often occurred. Now that's no longer the case. However, it is still necessary to pay attention to the working frequency of the needle detector when using it. This is very important for detecting relatively small metal products.

Since the size and packaging materials of each product are different, it is generally necessary to change the operating frequency of the detector, so the wide-band detector can detect more types of products under the condition of ensuring the sensitivity. Sometimes, the inspection machine needs to detect products of metal packaging materials; sometimes, it is necessary to detect products of small size or non-metallic packaging materials, so the inspection frequency should be changed according to the different products. It is necessary to choose a broadband detector.

The metal detector can maintain high detection sensitivity on the production line, thanks to several advantages in the design of the detector, such as enhanced anti-vibration (EVI) performance, through the advanced internal structure and coil system, it can be stable Vibration to reduce unwanted signal interference; dynamic filtering and enhanced noise suppression (ENI) performance reduces electrical interference and noise pollution generated by the air.
