PT Bunestar Sinar Dunia – The parts that are incorporated into your measurement and alignment system have all been developed with a view to a specific need or application. However, in general, there are four elements that should always be included and should not be separated.
When you choose a laser measurement system, what factors do you consider? Of course, one aspect is what you will be measuring and aligning, so there must be software to meet your needs. You can see the battery life, to ensure that you can work a full shift without taking a break. Depending on the environment you work in, you may need better dust and water resistance, such as IP67. Or systems that are intrinsically safe for potentially explosive environments. Which underlying technology to use may also be of interest, as this can limit your choices. For shaft alignment, line and point lasers are available as an alternative.
Line lasers provide a large measuring range at a relatively low cost, and are very easy to use during shaft alignment on machines without major sources of error. Line lasers are also ideal for belt pulley alignment.
If we break down the system, it consists in principle of four components: laser transmitter, detector, bracket, and software/display unit. What should you think?
- Laser Transmitter
Laser transmitters may have a seemingly simple design. However, to achieve the stability and precision required by industrial applications, many hours of design work are required. In this situation, mechanics and optics interact at the highest level. Depending on the area of application desired, there may need to be different types of light focusing optics, various solutions to allow laser sweep over the surface (rotating), various options for aligning the laser beam horizontally or along the measuring object, etc. It
For geometric applications, the laser is a separate unit. The Easy-Laser shaft alignment system has a laser and detector (see PSD below) mounted on the same housing. We call this a “unit of measurement”.
The next unit in the measurement system is the detector. It has a PSD (Photo Sensitive Device) detector which reads the position of the laser beam on its surface. A PSD that reads in two dimensions/axis (X/Y) is at the same time more expensive than a single axis unit. The larger the PSD surface, the larger the measuring range you will have. First and foremost, I’m referring to what can be compared to “strike length”, i.e. how much the position of the measuring object can be allowed to vary. However, because the diameter of the laser beam varies with distance, a larger PSD may also be required to measure at very large distances.
To measure correctly, the transmitter and receiver must be installed in a stable manner. This is where the parentheses come into the picture. Our brackets have been developed against the background of years of experience from our own measurement tasks, as well as from dialogue with our users. They are designed to be easy to attach to the measuring object, while ensuring the correct measurement value in all situations. They can also be adapted for different types of machines.
- Software and display unit
Today, most user interfaces are in color, with clear and attractive graphics that help users make measurements and alignments in the simplest way possible. Here at Easy-Laser, we have simplified the software and made it more user-friendly
