15.2.5 HAMAR SYSTEMS
The operating principle of the Hamar laser alignment systems is based on a single laser, dual
detector 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. The
operator then positions the laser and detector assemblies to center the beam in the detector
target 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 a
laptop 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 user
through the alignment process.
The Model S-650 system is shown in Figure 15.13. The detector target output is transmitted
via 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 software
program and laptop computer are supplied with the system.

FTECHNIK SYSTEMS
The first useable laser shaft alignment system was introduced by Pru
¨
ftechnik in 1984. The
operating principle of this system is shown in Figure 15.2 where a single laser, mounted on
one shaft, is aimed at a roof prism, mounted on the other shaft, which reflects the beam
directly 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 each
shaft, the operator installs the laser–detector head onto one of the brackets and the roof prism
onto the other bracket. Using the display and keypad, the operator enters information about
the drive system being aligned and once the laser beam starts operating, the operator adjusts
the 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 to
capture the shaft positions.
The first Optalign system incorporated an infrared laser (not visible to the naked eye) but as
visible lasers became available, they were incorporated into subsequent models.
The Pocketalign system is shown in Figure 15.14. This system utilizes a personal digital
assistant (PDA) for the operator and keypad. The PDA operating system requires Microsoft
Mobile 2003 and a CF II interface card is required. It uses the same laser–detector head as
the Smartalign system. The PDA can be purchased through the manufacturer or you can
buy your own. Communication cabling is provided to transfer files from the PDA to a
personal 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 been
the 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 basic

configurations, the ‘‘Entry Level’’ model and the ‘‘All Features’’ model. This system is also
fully 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 clamping
onto shafts up to 8.5 in. in diameter, posts (200 and 600 mm) for attaching the laser–detector
and prism to the brackets, a computer cable and adapter, tape measure, manual, cleaning
cloth, protective covers, and a carrying case. Optional firmware can be purchased which can

The Smartalign system is shown in Figure 15.16. The laser–detector transducer visually
looks the same as the Optalign Plus where the operational software is actually imbedded in
the transducer. In the case of the Smartalign system, the operational software is actually
imbedded in the operator keypad and display. The system comes with: the laser–detector
transducer, the prism, an operator keypad–display, 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, ‘‘smartREADER

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,

thermal growth entry for all machines in the train, infrared data transmission to computer,
and U-joint (Cardan shaft) alignment. Additional software packages enables alignment of
machinery bores (Boralign) and straightness and flatness (Levalign) measurement.

15.2.7 SPM INSTRUMENT INC.SYSTEM
The LineLazer system is based on the reverse indicator method and uses a dual beam–dual
detector system (See Figure 15.19). The LineLazer is an accessory that interfaces with the
Leonova 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 each

bracket. 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 angular
position of the shafts. A wireless transmission sends the detector signals to the operator
display. The operator then rotates the shafts to capture the shaft positions. Once the
measurement process has been completed, the user then obtains the corrective moves for
the machine selected as the movable machine.
LineLazer system cost: US$5500.00 (does not include the cost of the Leonova interface
system)
