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.

15.2.6 PRU¨ 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
