Professional metal detection is one of the services offered by GeoScan. It is an accredited company that specialises in underground utility, structural and geophysical investigation. This firm employs experts in detection of cable faults, cable location and underground pipes. GeoScan owns modern technology and equipment that it can use in the metal detection process.
Ferrous metal detectors are employed in cable and pipe location. The detector is said to be capable of searching for galvanised pipes, cast iron and steel.
It is capable of finding concealed box covers for irrigation and utility valves; buried taps and meter services; metal and concrete caps; and, underground storage tanks made of metal. The discovery of metal is considered an essential industrial process regardless of industry. This includes food, bakery, dairy, pharmaceutical and textile industries. Businesses need to be assured that their products are absolutely free from metal pollution. Metal detection services introduce an effective safety solution that can avert any contamination.
GeoScan can help mining companies capitalize on modern metal scanning resources because of technology progression. In fact, it is acclaimed as one of the leading companies in scanning (sub-surface) of valuable mineral deposits. The company is in the process of acquiring sophisticated software, novel scanning technology and capability to implement accurate data assessment. It is important to note that the company also conducts site survey and drafting making use of Auto CAD technology.
One area of interest is the method of how industrial metal detectors work. The most popular technology being used at present is called induction balance or Very Low Frequency. The VLF detector is made up of the transmitter and receiver coils. The first is an outer loop which covers a coil of wire. Electric power passes through this object in two directions (several thousands of times per second).The frequency of switching of direction every second creates the unit’s rate of recurrence.
The second is the receiver or inner coil loop with its interior wire functioning as antenna to pick up and magnify frequencies emanating from target objects beneath the ground. Electric current which passes through the transmitter produces an electromagnetic field. This is similar to that of the electric motor. The magnetic field’s polarity is at right angle against the coil. Every time current shifts direction, magnetic field polarity also changes. In other words, if the wire is parallel to the land, the magnetic field pushes down to the ground and pulls out of it. On the other hand, the fundamental method of detecting metal is through the Beat Frequency Oscillator or BFO.
GeoScan specialists have been trained to detect materials such as metal. Moreover, these technicians are well-versed in performing beneath-the-ground, obtaining evidence to be utilized for forensic research, archeological artifacts, and storage reservoirs buried under the earth’s surface.
