LIF SAFT ICIT AAGT Intelligent Heat Detectors

Very Low Frequency (VLF) detectors are the most versatile metal detector types, based on the range of metallic objects you can find with them. They are IB (Induction Balance) detectors using very low frequencies. As all IB designs, the VLF detector combines two balanced coils: the outer coil acts as a transmitter, using alternating current to create a magnetic field that is distorted by a ...

Science of metal detecting and treasure hunting.

See, in a metal detector its frequency is the number of electronic waves sent into the ground to detect metal objects. For example, 8 kHz frequency denotes your metal detector will send and receive signals 8000 times per second. Commercial metal detector frequencies range between 3 – 100 kHz as a general rule (https://metaldetectorsa.co.za ...

The current description focuses on PI detectors, as these were the circuits available and therefor could be tested in real life. Other designs like IB and BFO-ish will be tried out and documented at a later point of time. For the PI detectors two basic designs were used: the usual decay curve design (in my case without an additional OpAmp)

Jun 15, 2018· The shorter the delay, the more sensitive the detector is to small items and hot rocks. In theory a PI can be just as sensitive as an IB detector by operating at extremely short delay times, but then it would suffer the same problems as an IB detector. PI detectors designed to hunt gold often have a pulse delay of about 10uS (microseconds).
