Henan security gate metal detector how to use

1, a high level of security function

Requirement for metal detector door with a high degree of security needs, including the following

Passing through the security gate

a factor:

(1), the consistency of the magnetic field uniformity is the key to the 100% detection rate;

(2), the security detection force must be enough to detect any hazardous metal objects, regardless of the Its entry position and the angle at which it is how;

3, the security check detection force must be sufficient to detect the personnel at any speed under the passage of the inspection;

4, to have the ability to detect both ferrous and non-ferrous metals.

Peak high level of identification

Requires the ability to distinguish small quantities of hazardous metal items (e.g., small arms) from various types of metal substances carried by individuals.

The ability to discriminate is based on the following factors:

(1) uniformity and consistency of the magnetic field distribution;

(2) the ability to analyze various types of metallic substances;

(3) immunity to noise interference from external electric motors;

(4) immunity to mechanical interference from external sources;

excellent immunity (to noise interference) to ?°noise interference?±

Noise interference is an important reason that affects the performance of the metal detector door play. And noise interference is divided into the following types:

(1), instantaneous noise: motor, electronic control locks, power lines on the *** load of noise;

(2), intermittent noise: power supply equipment in the voltage generated by the radio frequency noise;
