1. STEP 2 Instali the rock bolt into the borehole so that the collar of the yellow target is 3 5 inches 30mm rom the collar of the borehole Using a 13 16 socket to grip the yellow aluminum target tighten the expansion shell until ho bolt is secure H Rock Bolt Yellow Hexagonal Aluminum Target Ring Magnet d GMMISPECTRE User Mannal Jon 2011 H STEPS With the bolt secure insert and attach the electronic probe to the borehole collar so that the niil reading is 15 00mm During this stage the sensor can be hold in place by an oversize ring ot electrical tape wound on the d GMMISPECTRE sco figure below The GMM can be permanently secured in place using either rock bolt resin or expansive foam 4 Rock bolt resin Mould the resin around the body of the sensor this provides the majority of adhesion and around the aluminum faceplate 2 Expansive foams When using expansive foams apply a Iberal coating of grease to tho aluminum target piace Then position the sensor in the borehole and spray a small amount of the foam Complete the application by filing around the collar of the borehole and enclosing the aluminum face bar In wet holes provide a drain hole using a length of tubing Rock Bolt Hex Aluminum Target cal tape 107 Ring Magnet SPECTRE GMM IMPORTANT If hole is wet use drain tubing Install the d GMM so that it has a initial reading of around 15mm The a2. engineer s spreadsheet program Proparation Customers use d GMM SPECTRE s in a wide range of applications not just attached to a rock bolt as a GMM Therefore if the d GMM SPECTRE is to be attached to a rock bolt the ring magnet needs to be epoxied into the yellow aluminum target at the ond which is not internally threaded Le at the far end from that which will thread onto tho rockbol A plastic centralizer is provided for this purpose For Installation the following items are required 1 4 GMM SPECTRE Manual Interrogation Unit d READER 2 Ratchet socket driver with 13 16 socket 3 2 rois of electrical tape 4 Expansive foam or rock bolt epoxy 5 Drain tubo for wet holes a drinking straw will usually suffice In typical applications the ring magnet will be attached to the aluminum target using an epoxy resin This should be done ahead of time 4 GMMISPECTRE User Manual Jan 2011 3 Installation Procedure Tho d GMM SPECTRE is designed for installation in a 1 3 8 diametar 33mm or larger percussion dril hole STEP The yellow aluminum target with magnet attached should be threaded and tightened onto a IB mechanical rock bolt a coupler exits for a 2 bolt The best tool to accomplish this is a professional quality ratchet socket driver see below with an extension and a 13 16 socket Tip In a pitch use a spark plug driver une Extensi n The Extension and 13 16 socket can be obtained from Yield

4. E the following digital operations are conducted 1 A displacement sensor monitors the relative position of the hermeticaly sealed electronic probe and a ring magnet which is usually housed inside a yellow aluminum target 2 A digital temperature sensor monitors temperature 3 A microcontroller applies signal processing digital fitering temperature compensation and linearization 4 The microcontroller outputs a digital signal on a single wire that aro directly related to real World unis 5 These signals can be transmitted over long lead wire lengths and are accurately decoded by another micro contraller in the Manual Interrogation Unit READER d LOGGER data logger or DESTINY networking system A digital approach is better because 1 Information can be sent over long lead wire lengths comparable to 4 20mA loops and orders of magnitude further than analog voltage signals 2 By using a time domain multiplexing scheme many channels of information can be sent along a single signal wire which reduces price and minimizes the timo required for any epar 3 accidentally severed lead wires can be twisted together as a temporary fix A Expensive A D conversion has already been performed in the sensor so that Data Acquisition can be buit around low cost microcontroller 5 Output in real world units decreases the cost of data interpretation and expands the number of personnel who can use the dala Many times data gels trapped in an
