The Industrial Food Grade Tunnel Metal Detectors for Conveyors are a great choice for any conveyor system. These metal detectors are constructed with a durable aluminum frame that is designed to withstand harsh environments and heavy use. The tunnel metal detectors have an easy-to-read display, making it easy to see if there are any objects in your conveyor system.
Industrial Food Grade Tunnel Metal Detectors for Conveyors
Tunnel metal detectors are used to detect the presence of metal in an industrial application, and are also commonly used in the food industry to detect food grade materials. These tunnel metal detectors can be used in a variety of industries, including construction, mining, and manufacturing. Food grade tunnel metal detectors are designed with high precision and accuracy to ensure that they provide accurate readings for their customers.
Food grade tunnel metal detectors have been designed for several different applications within the food industry, such as quality control or customer service departments. The main purpose behind these machines is to help ensure that all products are safe for consumption by consumers. This type of machine typically uses sensors that detect the presence of metals such as gold, silver, copper, zinc, nickel and iron among others.
The main advantage of using a food grade tunnel metal detector is that it can be easily integrated into existing processes without having any negative effects on production or quality assurance standards. They are also ideal for use in warehousing facilities where there may be issues with theft or damage caused by thieves who want to steal valuable goods such as gold bars or jewelry items stored inside these facilities
Industrial food grade tunnel metal detectors are used in the food industry to detect metal objects on conveyors. This type of detector is a great option for those who are looking for a more affordable and portable solution that still performs at a high level of quality.
We offer two models of our industrial food grade tunnel metal detectors: the [model name] and the [model name]. Both models have been designed with the same goal in mind: to be able to detect objects as small as ten microns-the size of most metals-in a variety of applications. The difference between these two models lies in their size and power requirements. The [model name] is smaller than the [model name], which allows it to be used in areas where space is limited, such as indoors or underground. The larger model has more power than its smaller counterpart, however, so it can be used outdoors if necessary (although this will affect its ability to pick up small items).
Food safety is at risk from metal shards and broken machinery that are left behind during manufacturing. This is why metal detectors are so common and integral to the production line.
The current practice in the apparel or garment industry is to use metal detecting after garments have been completed sewn. Before garments can be packed, to check for any metal contamination (needle broken, etc.). In the garments. This is necessary for safety reasons.
It is suitable for detecting metals in clothing, food, and chemical in field requirements.

Basic Principle
A 3 coil design is the basis of the operation of the food/industraial detector. This design uses an amplitude modulated transmitting and two receiving coils, one on each side of the transmitter. The physical design and configuration of the receiving coils is crucial in the detection of very small metal contaminants of less than 1 mm. Modern metal detectors still use this design to detect tramp metal.
The coil design is such that the coil creates an opening for the product (foods, plastics and pharmaceuticals, etc.). The coils allow the product to pass through them. This allows the product to pass through the coils. The three coil system produces an equal signal, but it is mirrored on the receiving coils. These signals are combined, effectively nullifying one another.
