Primary Applications for Standard ProbesRotating scanner probes are used with mechanical devicesfor automatically rotating the probe in the hole. Probesutilize reflection differential coils with operating frequenciesof 100 kHz to 2 MHz are typical. They bear close tolerancesand are highly reliableManual bolt hole probes have coils located at right anglesto the probe direction, and are rotated by hand with the fastener removed. Standard (fractional and metric) and customdiameters are available with absolute and differential coils.Surface probes have smaller diameter housing and coils builtfor higher frequencies. Applications are usually limited tosurface flaws because of the higher frequency and smallercoil size. Included in this type of probe are the right anglesurface probes and flexible surface probes, which are designed to reach areas inaccessible to the standard straightsurface probes.Spot probes are used for discovering flaws both on and below surfaces. Available in a broad frequency range, their diameters are usually large for accommodating lower frequencies or scanning large areas. Because spot probes containlarger coil diameters the detectable flaw size also increasesand is typically limited to ½ the probe diameter.Weld probes are designed to inspect ferrous welds. They provide a cost effective alternative to magnetic particle inspection, which requires the part to be prepared (cleaned) priorto inspection.Sliding probes are designed to inspect aircraft fastener holeswith fasteners in place, at higher scan rates than donut (ring)or spot probes. Common sizes and frequencies using thereflection coil techniques are often applied in major airframeinspection requirements.Conductivity probes are designed for sorting non-ferrousmetals, determining heat treatment condition or damage.4www.olympus-ims.com

Rotating Scanner ProbesBolt Hole Probes for Olympus Rotating ScannersRotating scanner probes are available in a variety of diameters and styles to work with Olympus rotating scanners. The SPO-5965 andSUB series probes are fitted with a 4-pin Fischer connector while the SPO-3564 series incorporate the 4-pin LEMO connector style.The probes listed on this page are designed to be rugged and are nearly indestructible when dropped or expanded. Their probe tips haveflexible plastics tips that automatically compress to their original size after being expanded to fit inside larger bolt holes (see chart belowfor hole size ranges). The benefit of these flexible tips is that no additional manual adjustment has to be made to the probe after a bolthole has been reamed to a larger diameter.Rotating scanner probes use a reflection differential type coil operating in the 200 kHz to 3 MHz range. They are suitable for aluminumstructures as well as low conductivity materials.Working Length 0.5 mmWorking Length 0.5 mmFischer ConnectorSPO-5965*Range of Hole Sizemm (in.)LEMO ConnectorSUB -3564**WorkingLengthmm (in.)PartNumberItemNumberWorkingLengthmm (in.)3.2 to 3.9(0.125 to 0784U861410928.0(1.10)3.9 to 4.7(0.156 to 30078U861405928.0(1.10)4.7 to 5.5(0.187 to 7153U861409128.0(1.10)5.5 to 6.5(0.218 to 17154U861409228.0(1.10)6.5 to 7.1(0.250 to 17155U861409328.0(1.10)7.1 to 7.9(0.281 to 17156U861409438.0(1.50)7.9 to 9.5(0.312 to 17157U861409538.0(1.50)9.5 to 11.0 (0.375 to 17158U861409638.0(1.50)11.0 to 12.7 (0.437 to 17159U861409738.0(1.50)12.7 to 14.3 (0.500 to 17160U861409838.0(1.50)14.3 to 15.9 (0.562 to 18785U861409938.0(1.50)15.9 to 17.4 (0.625 to 18786U861410038.0(1.50)17.4 to 19.0 (0.687 to 18787U861410138.0(1.50)* For use with MiniMite Fischer, Spitfire, and other "Universal" scanners.** For use with MiniMite LEMO, RA19, and RA2000 scanners.6www.olympus-ims.com

Sliding ProbesSliding probes are specifically designed to inspect rows of fasteners. They operate in the reflection mode (Driver/Pickup coils) and areused to find surface and near-surface flaws. Available in two different types; adjustable types (as shown in picture below) include shimsthat allow the probe to be adjusted to accommodate different fastener sizes and include microdot connectors. Fixed types are capable offinding the same flaws as the adjustable but usually are procedure specific due to coil size and frequency range. The fixed versions typically include the Fischer/LEMO triax connector and the underside of the probe is relieved to allow the probe to easily slide over raisedfastener heads.LHWDimensionsmm (in.)12Part NumberItemNumberLTW0419-1U8633025Adjustable100 Hz to 5 kHz25.4(1.00)85.1(3.35)19.1(0.75)(2) 1-pin MicrodotLTW2018-1U8633056Adjustable500 Hz to 10 kHz25.4(1.00)44.7(1.76)25.4(1.00)(2) 1-pin MicrodotLTW0423-1U8690009Adjustable500 Hz to 10 kHz25.4(1.00)44.5(1.75)25.4(1.00)(2) 1-pin MicrodotLTW5010-1U8690010Adjustable1 kHz to 20 kHz25.4(1.00)25.4(1.00)25.4(1.00)(2) 1-pin MicrodotLTW1022U8633026Adjustable5 kHz to 100 kHz25.4(1.00)38.1(1.50)19.1(0.75)(2) 1-pin MicrodotNEC-4039U8636053Fixed1 kHz to 100 kHz25.4(1.00)38.1(1.50)20.3(0.80)Fischer/LEMO TriaxNEC-4039-1U8633054Fixed1 kHz to 100 kHz25.4(1.00)38.1(1.50)20.3(0.80)2-pin MicrodotNEC-4039-2U8633055Fixed1 kHz to 100 kHz25.4(1.00)38.1(1.50)20.3(0.80)4-pin FischerNEC-4039-3U8629545Fixed1 kHz to 100 kHz25.4(1.00)38.1(1.50)20.3(0.80)(2) 1-pin MicrodotNEC-4039-7LU8633027Fixed1 kHz to 100 kHz38.1(1.5)58.4(2.3)30.4(1.2)7-pin LEMOTypeFrequency RangeHeightLengthWidthConnectorwww.olympus-ims.com

Eddy Current Probe Selection InformationThe selection of the right eddy current probe is of great importance in the success of your inspection. In these pages, we have includeduseful information to help you make the right choice.Absolute Probes (Single-Coil Probes)OSCThe earliest form of eddy current instruments operated with asingle-coil probe that was wound to a specific value frequency.Many newer models of eddy current instruments have kept thiscircuitry as a popular option for users while also incorporatingmore sophisticated functions. When these probes are used, a balance coil is also required which may be set from within the eddycurrent instrument or is commonly found within the probe housing, the cable connector or in a separate adapter (see Fig. OSCReference coilDetectorsFigure 3DetectorsAbsolutedisplayOSCTest coilAbsolutedisplayFigure 1A problem can arise when the probe inductance value is not closeenough to the value of the balance coil causing the instrumentnot to balance correctly. The result is poor performance (noisy orinsensitive) or no response at all (signal saturation).Bridge Type ProbesIn this configuration the probe coils are located in an electrical”bridge” (see fig. 2). The instrument balances the bridge and anychange in balance is displayed as a signal. In this arrangement,the same coil produces the eddy currents and detects the impedance changes caused by the defects (or any other variables).Almost all instruments are able to operate with this type of ayReference coilTest coilFigure 2Reflection Type ProbeThese probes are also known as send-receive or driver-pickup. Inthis configuration, the eddy currents are produced by a coil connected to the instrument’s oscillator (driver). The signals receivedback in the probe are detected by separate coils called pickups(see Fig. 3 and Fig. 4). All new impedance plane instruments andalso many older models are able to operate in both bridge andreflection modes. If you are in doubt, call the manufacturer orgive us a call.16DriversPickupsFigure 4Bridge or Reflection?This is a common question asked by those involved in trying toselect the best probe for an inspection. The answer is ”It depends.”Let us consider both systems.Gain: Reflection probes will give a higher gain, particularly if theyare ”tuned” to a specific frequency, but normally the difference ison average about 6 dB. It is true that this doubles the signal, but ifyou consider that the instruments are able to give this increase ofgain easily, it is not so important. Nevertheless, in critical applications this increase is very welcomed.Frequency range: Reflection probes do not need to balance thedriver to the pickup coils. This means that they will give a widerfrequency range. As long as the driver produces eddy currents, thepickup will detect them and some signal will be disp

An eddy current inspection was performed on the tubes in this machine. This test was performed using accepted eddy current test methods for the inspection of in-service tubing. It should be noted that Eddy Current is not a leak detection method. The possibility does exist that tubes could contain defects and/or leaks which are not detectable.
The eddy current brake implements the idea introduced above to generate a torque sufficiently large that resists the rotational motion of wheels. Figure 2 shows the schematic diagram of a simple eddy current brake with only one magnet around it. The subsequent analysis is based on this simple model.

Accounting information and managerial work. Accounting, Organizations and Society, 35 (3), 301-315. ABSTRACT . Despite calls to link management accounting more closely to management (Jonsson, 1998), much is still to be learned about the role of accounting information in managerial work. This lack of progress stems partly from a failure to incorporate in research efforts the findings regarding .
