9 2. Product description This chapter contains information about the characteristics of EBEX Description The detector system EBEX 410 is a high sensitive metal detector system, equipped with numerous components to suit for various inspection tasks. The versatile nature of the system allows for more than 50 different equipment configurations. For detailed inspection and body search it can be assembled as a wand, using the small halo coil or the cylindrical probe. For land use extension rods and a large halo search head are supplied. To inspect areas which are difficult to reach an extension cable can be connected between the extension rod and the halo search head or cylindrical probe. 2.2 Main characteristics versatile detector kit for many different search tasks very high detection sensitivity dynamic operation mode Simple handling: single-button operation automatic compensation of steady background interference automatic operation and battery control sturdy design, shock-proof packing in aluminum transit case with liner water resistant 9

12 3.2 Identification The electronics box carries a label showing the detector type, serial number, and the equipment manufacturer s name. Pic. 6: Detector type and serial number

13 4. Application The connectors of all EBEX 410 components are designed to fit all sensors directly to the electronics unit or by means of the extension rods or the flexible cable. Due to the compact and user friendly design the detector can be operated without external boxes or disturbing cables. Operation and calibration of the EBEX 410 is made easy by a single counter sunk adjusting knob. The detector electronics and battery compartment are built into the electronic unit which is splash water and tropic proof. The EBEX 410 is a strong, shock proof and lightweight detector which meets the Forensic Investigation Technology quality requirements, the detector is stored and transited in an aluminum case. Pic. 7: EBEX 410 in transit case 13

14 5. Principle of Operation The EBEX 410 detector system operates after the highly efficient EB damping system. In 1971 this working principle was applied already for a cartridge detector used in forensic police work. Its function is described hereafter: An oscillator in the detector electronics sends an AC signal to the search coil. The coil transmits an alternating electromagnetic field inducing eddy currents into metal targets which come within the detector coil s reach. The eddy currents create a secondary field around the detected metal object and absorbs energy from the detector electronics reducing the amplitude of the transmitted signal. This change in amplitude is electronically measured, processed and converted into an audio detection signal. Primary field (search coil) Secondary field (target) Pic. 8: Working principle of the EB 410 detector The primary field has to cross the distance between search coil and target. The secondary field has to run distance back this again. This means that the signals have to run the distance twice through the corresponding media (air, water, soil, wood or brickwork). After the end of the transmission pulse the receiver is activated between 2a and 2b depending on the selected position of the delay adjuster knob (O 250 μsec) The detector will evaluate the remaining response signal (2a/2b to 3) and convert the signal into an audio and galvanometer indication. Large conductive objects (i.e. metal) respond with longer and stronger response signals than small objects. Salt water or mineralized soil shows a fairly short echo in comparison to metal objects.

15 6. Assembly Select and assemble components according to the detection task. For combination examples see point 3. General rule for the choice of the appropriate search head /coil: for small metal objects small search heads (minimum amount of metal mines, cartridges and projectiles); for larger metal objects large search heads (UXO, weapons etc). For search inside buildings and for a thorough inspection after small metal objects select the cylinder tracer due to good resolution between several metal objects. The electronics, carrying rods, extension cable and the coils are connected by co-axial threads. The rear socket at the electronics cylinder takes the headphone plug or the loudspeaker. Pic. 9: Screwing the electronics cylinder onto a detector coil 6.1 Starting Fit battery to the battery compartment as per pict.7 and rotate countersunk adjuster to put the device into operation. Short control clicks audible every 3 seconds in the speaker or headphone indicate that the detector is ready for use and that the battery is fully charged. 15

16 6.2 Selection of the search coil The different search coils of EBEX 410 make it possible to optimize the detector to the task. Each coil has its typical range of targets and jobs to which it will fit best. This range is mainly predetermined by the corresponding alternating magnetic fields of the targets. The cylinder tracer probe provides a very focused and compact field which is most sensitive to very small targets. This field concentration gives a strong indication of targets close to the probe and reduces interference from surrounding metal objects. The cylindrical probe eases a pinpointing of targets. It is appropriate to inspect narrow areas. It provides a very good resolution and a precise indication. Its maximal detection range on large targets is approx. 30 cm. The search coil Ø 145 mm should be applied for the location of small targets such as i.e. cartridges or projectiles to be found in open ground. Due to its small diameter it has a concentrated electromagnetic field with a maximum detection range of approx. 1 m. This also means that it can be affected by large metal surroundings close to the search coil if the detector is adjusted to high sensitivity. It can also be used in rooms to check persons on weapons or to check suspicious mail, lost property and objects suspected to contain explosives. Penal institutions use the coil to detect hidden cell phones, one-way shavers etc. and swallowed metal objects. The detection range factor of the small ring coil is approx. 3,4 in air, meaning that an iron disk of same diameter as the coil may be indicated up to the 3,4 fold distance, i.e. 145 mm X 3,4 = 49,3 cm. The depth range of the coil is about 30 to 40 cm. Pic. 10: Range diagram of the detector EB 410 with search coil dia. 260 mm The diagram above shows the max. theoretical detection range (dotted line) and the limits of the detection depth range in the ground (steady line) to explain the efficient range of the detector and where it works most efficiently (hatched surface)

17 The detection range was tested with several metal discs of different sizes which had a detection surface of 10 to 500 % of the search coil surface to establish the shown diagram. It becomes evident that a target size increase beyond 400 % does not cause a remarkable increase in detection range. The limits of detection range of the detector are approx. 80 cm to 90 cm in favourable search conditions with hardly any interference. The coil Ø 260 mm has the largest detection range on metal objects of some size. Range factor is approx This max. detection range is applicable to a sensitivity check in air. This value is of little importance for a real search operation as it does not represent realistic conditions with a wide range of possible sources of interference. It is necessary to deduct about 10 20% from this value to get closer to realistic values. Rotating the countersunk adjuster switches the EBEX 410 into operation. The detector requires approx. 2 minutes for warm up. Max. sensitivity is achieved with the adjuster tuned precisely below the audio alarm threshold. For delicate jobs it is advantageous to set the detector to a low-frequent pulse-like basic audio signal. Metal objects cause a frequency change of the basic signal what can clearly be perceived. The EBEX 410 has dynamic detection characteristics requiring a movement between the detector coil and a metal object to provide the indication signal. When the coil is held steadily next to a metal object the indication will decay to no signal or to the preset basic signal after a short delay. The consistency regulating and compensating time depends on the size and distance of the metal object. The advantage of this dynamic mode of operation is the fact that the detector automatically adjusts itself to the prevailing electric location and ground conditions. Also background metal construction can be compensated for if the detector operates at a steady distance to them (i.e. parallel to railways or fences). The search is conducted by systematic scanning of the surface. Large areas shall be subdivided into search lanes and grids. Keep detector coil as close as possible to the ground. If the area to be inspected does not allow access for the large search coil or if it proves to be difficult to scan or reach (bushes, roots, hollows) use small coil or probe. A sudden audio signal indicates that a metal object is detected. The signal frequency rises as the object is approached. When the highest frequency is perceived the object will be found under search head center. Always inspect search area in a go and return scan! The audio signal intensity and geometry depends on the size, position and depth of the detected metal object. A short but strong audio signal starting and breaking off on a small area indicates a small metal object on or near the surface. Whenever the indication increases slowly over a larger area the device either detected a deep buried large metal object or non-cooperative ground. 17

18 Indication Pic. 11: Detection of large objects Indication Pic. 12: Detection of various objects A Indication of a small shell buried horizontally B Indication of a small shell buried vertically in the ground C Indication of a small metal object D Indication of a metal object buried horizontally Experienced user will successfully conclude size, depth and location of metal objects As mentioned, the EBEX 410 is a versatile tool which suits various roles and terrains. In addition, due to its very high sensitivity it can be used for forensic police work and in law enforcement. For this field of application a modified version is available. For the use in the field of law enforcement the large ring coil can be replaced by a mid-sized coil of Ø 200 mm.

19 6.3 Depth range In detection technology depth range is a difficult issue because detection results do not only depend on the operator s concentration and perceptive faculty but also on the respective working conditions at the work site. Technically the depth range of a detector - no matter of what design - depends on the size, position and material of the target objects as well as of the local interference. For this reason reproducible detection ranges can only be quoted for sensitivity checks in air. Picture 5 shows a diagram of range of the EBEX 410 detector with search coil Ø 260.mm. The upper dash-dotted line shows the max. detection range in air. The lower line shows the depth range that can be expected in favorable search conditions without interference. It is advisable to deduct 20 % of the maximum detection range to get realistic values. 19

20 7. Power supply Battery voltage is monitored by audio clicks. One click every 3 seconds indicate that battery fully charged. As battery voltage drops the click frequency will increase. One click per second indicates that the battery approaches the end of its service life and has to be exchanged (rechargeable Ni-MH battery needs recharging) soon. As soon as voltage drops below nominal value a continuous alarm of 100 Hz will start which can not be cancelled by the sensitivity knob. Detector must not be used any longer. 7.1 Battery change Pic. 13: battery change Unscrewing the rear cover from the electronic cylinder gives access to the battery compartment (see picture 7). Watch for correct polarity as shown on sticker in the battery compartment when inserting a new battery. Alkaline batteries are to be preferred due to better capacity and storage life. The detector can also be operated on a rechargeable Ni-MH accumulator which can be recharged by the supplied 220 V plug in charger. A 110 V plug charger is available on request. Check for correct mains voltage! Recharging with EBINGER supplied chargers takes approx. 4-5 hours. See the instructions of the manufacturer of the accumulator. Avoid overcharging and low discharging of the accumulator.

21 8. Maintenance The detector should not be packed if dirty or damp. REMOVE BATTERY BEFORE STORAGE OF EQUIPMENT. DISCHARGED BATTERIES CAN LEAK AND DAMAGE TH BATTERY COMPARTMENT It is advisable to keep all coaxial screw connections dry and clean. Lubricants should be avoided at threads. Apply Kontakt60 only. In case of malfunction first check the battery, its polarity and contacts. For trouble shooting and fault identification interchange components with those from an operational detector. The detector should be repaired by authorized persons only. WARRANTY EXPIRES IN CASE OF INEXPERT INTERVENTION; IMPROPER OPERATION OR USE. THE DETECTOR MUST NOT BE STORED WHEN STILL SWITCHED ON. RECHARGEABLE BATTERIES NEED A REFRESHER CHARGE ONCE PER MONTH! The detector is a splash-water proof design and can be used in bad weather, rain or wet grass. It can be used in shallow water but is not designed for underwater use. For underwater use a pressure water proof equipment (UWEX 722) is available. 21

22 9. Interference In the field of detection technology interference is an important factor. It often depends on interference whether a detection task can be successfully finished or not. Interference means magnetic effects of the ground, contamination with metal fragments or scrap and even adverse ground conditions impairing the detection result. Severely mineralized ground, magnetic stones and road surfaces count among magnetic, non co-operative ground effects. Basalt rocks may cause interference by a negative reading (basic audio signal dropping tone below "0" when approaching and increasing once the sensor leaves the target area). It is often possible to distinguish between interfering signals and a detection signal by a positive / negative indication. Metal makes the audio alarm rise, magnetic ground makes it drop. To reduce magnetic interference use the coil in an angled (approx. 30 ) position towards ground. High metal impact areas can slow down an operation significantly especially if small metal targets have to be located. In this case every signal has to be checked.. Detection work inside rooms can be rendered difficult by the presence of metal constructions. In such case use small head or cylindrical probe. The detector detects all conductive media inclusive salt water impregnated ground. In such case use EBINGER PI systems. AC fields from electric power lines generally do not influence the detection results.
