The operating principle of the Hamar laser alignment systems is based on a single laser, dualdetector using a beam splitter as shown in Figure 15.4 A bracket is attached to each shaft.The laser is attached to one of the brackets and the detector target to the other bracket Theoperator then positions the laser and detector assemblies to center the beam in the detectortarget area

The Model S-640 system is shown in Figure 15.12 The detector target output is connected

to a computer interface module (Model R-358) via a cable, which is then connected to alaptop computer via the serial communications port An alignment software program sup-plied with the system is loaded into your laptop computer and the software prompts the userthrough the alignment process

The Model S-650 system is shown in Figure 15.13 The detector target output is transmittedvia infrared data transmission to a receiver–computer interface module (Model A-908), which

is connected to a laptop computer via the serial communications port An alignment softwareprogram and laptop computer are supplied with the system

15.2.6 PRU¨FTECHNIKSYSTEMS

The first useable laser shaft alignment system was introduced by Pru¨ftechnik in 1984 Theoperating principle of this system is shown in Figure 15.2 where a single laser, mounted onone shaft, is aimed at a roof prism, mounted on the other shaft, which reflects the beamdirectly back toward its point of origin but offsets the beam a specified distance so the laser

can strike onto the surface of the photodetector target After attaching the brackets to eachshaft, the operator installs the laser–detector head onto one of the brackets and the roof prismonto the other bracket Using the display and keypad, the operator enters information aboutthe drive system being aligned and once the laser beam starts operating, the operator adjuststhe position of the roof prism to center the returning laser beam onto the photodiode target.The operator then proceeds through the instructions prompted via the display and keypad tocapture the shaft positions.

The first Optalign system incorporated an infrared laser (not visible to the naked eye) but asvisible lasers became available, they were incorporated into subsequent models

The Pocketalign system is shown in Figure 15.14 This system utilizes a personal digitalassistant (PDA) for the operator and keypad The PDA operating system requires MicrosoftMobile 2003 and a CF II interface card is required It uses the same laser–detector head asthe Smartalign system The PDA can be purchased through the manufacturer or you canbuy your own Communication cabling is provided to transfer files from the PDA to apersonal computer for file archiving Continuous sweep measurement mode software can

be purchased separately

The Optalign Plus system as shown in Figure 15.15, now in its fourth generation, has beenthe workhorse of their product line The operational software is imbedded into the laser–detector sensor assembly, not the operator keypad and display It is offered in two basicconfigurations, the ‘‘Entry Level’’ model and the ‘‘All Features’’ model This system is alsofully configurable with the exact features and functions the user desires, ‘‘a` la carte.’’Intrinsically safe models are also available The system comes with the laser–detector trans-ducer, the prism, an operator keypad and display, a 6 ft (2 m) cable, brackets for clampingonto shafts up to 8.5 in in diameter, posts (200 and 600 mm) for attaching the laser–detectorand prism to the brackets, a computer cable and adapter, tape measure, manual, cleaningcloth, protective covers, and a carrying case Optional firmware can be purchased which can

save either 25 or 99 files, enter both vertical and horizontal target specifications and thermalgrowth data, vertical shaft alignment, multipoint measurement mode, alignment of spacershafts, machinery with 6 ft, ‘‘static feet’’ function for bolt-bound or base-bound machines,alignment tolerances, and extended measurement range (known as InfiniRange).

Optalign Plus Entry Level system cost: $6600.00

Optalign Plus Intrinsically Safe Entry Level system cost: $10575.00

Optalign Plus All Features system cost: $13500.00

The Smartalign system is shown in Figure 15.16 The laser–detector transducer visuallylooks the same as the Optalign Plus where the operational software is actually imbedded inthe transducer In the case of the Smartalign system, the operational software is actuallyimbedded in the operator keypad and display The system comes with: the laser–detectortransducer, the prism, an operator keypad–display, a 6 ft (2 m) cable, brackets for clampingonto shaft up to 8.5 in in diameter, 20 different posts of various lengths for attaching thelaser–detector and prism to the brackets, ‘‘smartREADER1

’’ software, a computer cable andadapter, tape measure, manual, cleaning cloth, protective covers, and a carrying case.Smartalign system cost: $14800.00

The Rotalign Pro system is a more advanced system than the systems described above and

is shown in Figure 15.17 The system comes with an alignment computer, a laser sender,

a receiver, a 6 ft (2 m) cable, brackets for clamping onto shaft up to 8.5 in in diameter,

20 different posts of various lengths for attaching the laser–detector and prism to the brackets,beam adjustment tube, a computer cable and adapter, tape measure, manual, cleaning cloth,protective covers, and a carrying case The basic software of this multifunction device enablesone to align horizontally or vertically mounted machinery, coupled or uncoupled shafts,alignment of multiple element drive systems, soft foot detection, target specifications andthermal growth entry for all machines in the train, infrared data transmission to computer,and U-joint (Cardan shaft) alignment Additional software packages enables alignment ofmachinery bores (Boralign) and straightness and flatness (Levalign) measurement.

Rotalign Pro system cost: $18900.00

Rotalign Pro Intrinsically Safe system cost: $23700.00

Boralign add-on package cost: $8500.00

Boralign Long Range upgrade package cost: $6969.00

The LineLazer system is based on the reverse indicator method and uses a dual beam–dualdetector system (See Figure 15.19) The LineLazer is an accessory that interfaces with theLeonova system, which is capable of doing vibration analysis and balancing with the appro-priate add-on hardware

A bracket is attached to each shaft and the laser–detector heads are then attached to eachbracket The operator then aims the laser toward the detector targets on the opposing shaft

and centers each beam Inclinometers are incorporated into the heads to measure the angularposition of the shafts A wireless transmission sends the detector signals to the operatordisplay The operator then rotates the shafts to capture the shaft positions Once themeasurement process has been completed, the user then obtains the corrective moves forthe machine selected as the movable machine.

LineLazer system cost: US$5500.00 (does not include the cost of the Leonova interfacesystem)
