Pulse metal detectors  technology PI

The Pulse metal detector or pulse induction metal detector  Is the most sensitive of all detectors , responds to any metals, does not distinguish between ferromagnets from diamagnetic . Search features allow the pulse metal detector to find gold and gold nuggets in alkaline conditions and extreme temperatures of the soil ( or rock) that are too complex for devices VLF / TR. It also allows detection of metal ores contained in the rocks and mud .

Pulse metal detectors are indispensable when searching the coastal zone, under water and in the highly mineralized ground . Work devices independent of the influence of land and water. They work equally well under water and on land. Therefore PI technology used in underwater metal detectors . The devices have good results when searching the wet sand and beaches. Depth of detection of objects in the ground and salt water more than the VLF metal detectors .
Pulse metal detectors . technology PI
Pulse metal detectors better than VLF metal detectors behave near power lines , as well as transmitting antennas of mobile communication systems . Serve this type of metal is quite simple. Typically, they are equipped with the only regulator of sensitivity, although more advanced models may have other controls .

The devices have high power consumption , need for powerful batteries . Conventional batteries is not more than 12 hours of continuous operation . If you use alkaline batteries , the duration of the work increases.

PI technology is not universal , and the disadvantages of metal detectors pulse limit their opportunities. Currently, the best metal detectors for all purposes are devices using the technology VLF ( very low frequency). However, the technology PI may have further developed in the future may be new devices with new capabilities .

Pulse Metal Detector. Operation Principle



Design and operation of pulse metal detectors

Pulse metal detectors have a simple design . The device consists of a pulse generator , the search coil unit amplifying the signal analyzer and the display unit . Coil system is also simple . It is transmitting and receiving simultaneously. This significantly reduces the weight of the unit .

Search coil affects primer pulsating electromagnetic field. The radiation pulse occurs at 50 … 400 Hz and an energy of about 100 watts. Due to magnetic induction on the surface of the metal object in the zone of the field eddy currents .

These currents are a source of a second signal ( the reflected impulse response ) . In between pulse , the receiver receives the response, which is amplified and processed by an analyzer and then displayed on the display unit .

The decay time of the reflected pulse is more than the decay time of the emitted pulse (due to self-induction ) . The difference in time is a parameter for analysis and recording . Attenuation of eddy currents from the soil or water is much faster and can not be detected device. That is why the pulse metal detectors effectively works under water, at mineralized , salty and moist soils.
