9 Laser Transmitters for different measurement needs

Four parts are key to quick and easy measurement with laser: a laser transmitter to emit a laser beam, a detector to register it, suitable brackets, and measurement software to display the result. In this article we will guide you through our different laser transmitters and their main areas of use.

Laser – a perfect starting point for precision measurement

The laser beam is the reference for the measurements. It can be compared to an absolutely straight and weightless ruler, that is to say a perfect starting point for precision measurement. But different measurement applications require different laser transmitters. Read on to learn more!

Versatile transmitters with swiveling laser head

Easy-Laser® XT20 / XT22 / D22

These transmitters can handle most types of geometrical measurements, like straightness, flatness, and squareness. The swiveling laser head gives a 360° laser plane parallel to the measured object, and the D22 and XT22 can also angle the laser beam 90° to the sweep for squareness measurement. The electronic levels of the XT transmitters ensure quick feedback and low risk of errors.

Both XT transmitters connect to the XT Alignment app. This gives you several benefits when it comes to ease of use. The app also warns you of temperature changes and vibrations that can affect the measurement results negatively. Step-by-step guidance during calibration of the units is another advantage.

What are the main differences between these three transmitters? Take a look in the table below.

D23 with a constantly rotating laser beam

Easy-Laser® D23 has a motor driven, rotating head that gives a 360° laser plane. The laser beam from the transmitter rotates constantly and creates a reference plane over the entire measurement object. Measurements are performed quicker as you do not have to align the beam for each new measurement position. The laser transmitter measures distances up to 20 meters in radius. This transmitter is mainly for flatness measurements.

D75 measures straightness of bores and more

The Easy-Laser® D75 laser transmitter is typically used to measure straightness of, for example, bores, stern tubes, and extruder barrels. The laser transmitter has a measurement distance of up to 40 meters, and brackets are available for many purposes

Bore alignment with the E950 system, which includes the D75 transmitter.

D146 measures spindle direction and straightness

Easy-Laser® D146 is a laser transmitter for measuring spindle direction and straightness. It can be used in a rotating spindle (max. 2000 rpm), and the laser transmitter measures on distances up to 20 meters.

Get it straight in turbine applications with D25

Easy-Laser® D25 measures straightness, primarily in turbine applications, but also on e.g. gear boxes. The laser beam can sweep 360° and can be angled 90° to the sweep. This way you can use the axial surface as reference when setting up the transmitter.

Turbine measurement

E30 for long range measurements

It is usually difficult to get a laser point that is qualitative enough to be detected with precision at long range. But with the Easy-Laser® E30 it is possible to take high-resolution straightness measurements at a range of up to 200 meters!  

Laser transmitter for sheave and pulley alignment

This transmitter is used to align belt or chain transmissions. The laser transmitter is mounted on one of the sheaves, and the detector on the other. The transmitter generates a laser plane parallel to the reference sheave. The detector reads the position in relation to the laser plane and provides a live digital display of both offset and angular value. This makes the alignment of the adjustable machine very simple.

The transmitter and detector are mounted on the sheaves with magnets.

We hope you now have a better picture of the different laser transmitters. Maybe you found one that responds to your specific measurement needs? Or, worst case, you did not find any that suit your requirements! Either way – feel free to contact us at sales@gvsensors.com.au.

Easier than ever to measure flatness and straightness

Now presenting Easy-Laser® XT20 and XT22, the most user-friendly precision laser transmitters ever designed! 
 

One of the most important things during a machine installation is to ensure the flatness of the base. With the new XT20 and XT22 we have facilitated handling, which makes for faster measurements and fewer fault sources. More reliable machine installation, put simply. 

Both transmitters can be used for flatness and straightness measurement. In addition, the XT22 can direct the laser beam at 90 degrees to the laser plane, which means you can solve virtually all types of geometric measurement jobs. The area of use therefore does not stop at measuring the flatness of bases. The XT22 also has a higher technical specification for straightness thanks to fiber laser technology, and can take measurements at distances up to 40 m. The XT20 can take measurements at distances up to 20 m, but is also IP55 rated water and dust proof.    

New technology improves reliability  

We have installed electronic precision levels in the XT transmitters. This gives the advantage of faster feedback when levelling and less risk of errors during calibration, because all users see the same angular value (compared with reading spirit levels).   

The laser transmitters are wirelessly connected to the XT Alignment app. In this way, the user can be guided during calibration and the measurement procedure. In the event of temperature changes, vibrations or impacts that can affect the measurement result negatively, the app gives a warning during measurement. Data about the transmitter and measurement environment can be downloaded together with the report. This all provides greater reliability and traceability for your measurement jobs.  

Functions for easier use  

The rotating head is completely stable and retains its position during measurement. At the same time, with the new fine turning mechanism it is easy to set the pointing direction of the laser beam to hit the detector, even at distances up to 40 m. We guarantee that this will be very much appreciated by users out in the field. All operation is also managed without the need to lock/unlock rotation, which facilitates use considerably.    

Just like Easy-Laser’s previous laser transmitter, the new XT20/XT22 can be installed and positioned in many different ways: with integrated super magnets, on rods to be height adjustable, on stands and magnetic feet etc. We know that this is an important factor in practice to combat all those situations the user faces in reality.   

A rechargeable Li-Ion battery gives long operating times, up to 30 hours. If necessary, the transmitter can also be run directly off the mains.  

Developed for use with the XT Alignment app  

The XT20 and XT22 are used with the programs Values, Basic flatness and Straightness (new) in the XT Alignment app.   

The laser transmitters can be purchased separately (as a kit with charger and fixture) but are also included in complete systems, such as the XT770 GEO. The XT70-M unit can be used as a detector. They can also be used with E series detectors. Note, however, that the XT Alignment app is required to calibrate the electronic levels, and other things in the design of the XT transmitters differ from previous products. Therefore, always ask us first if you plan to replace an older transmitter.   

Easy-Laser have been known for their reliable geometry measurement systems for decades. With the new Generation XT laser transmitters we are taking a step into the future, to a whole new level of reliability, precision and user-friendliness. The XT20 and XT22 are the laser transmitters of the future, in every way.

Create a Compressed Air Leak Management Program with SDT. It’s EASY

Why We Ignore Leaks
Compressed air is a misunderstood utility. As such, it tends to be misused and even abused. Leaks continue to be the biggest problem; often overlooked because they are difficult to detect, don’t smell bad, don’t make a mess on the floor, and rarely stop production.

 

The Real Cost of Leaks
One of your factory’s highest operating expenses is the energy consumed by your compressed air system. Only 25% of the cost of a compressed air system is capital cost and maintenance. The remaining 75% is energy, and as much as 35% of that energy is wasted satisfying leaks.

Additional Impacts
Compressed air leaks create fluctuations in system pressure, which negatively impacts product quality. Compressors work overtime to compensate, leading to early degradation of the asset. Eventually, the compressor system can’t keep up with demand. What can you do? Buy yet another compressor for more capacity? Or optimize the capacity you already have by finding and fixing leaks?

With so much at stake, why are compressed air leaks managed so poorly, and why doesn’t every organization have an air leak management program?

 

Where to Look for Leaks
Every component has the potential to leak, but we can hasten our search by focusing on common failure points. Usual problem areas are branch line connections, automatic drain traps, desiccant filters, regulators, coalescent filter assemblies, quick couplers, valves, hoses, fittings, pneumatic cylinders and thread sealants. Most leaks occur at points of use, so begin your search there.

How to Find Leaks
Locating air leaks in a loud factory floor is next to impossible with a human ear. The best, and easiest, way to find air leaks is using ultrasound. Ultrasound detectors allow you to hear the minute hissing noise produced by leaks, despite the roaring noise of a production area. Ultrasound detectors are portable, easy to use and require little training to get started.

SDT have a range of hand-held devices from the entry level LEAKChecker to the SDT340 which can be used for both airborne & structure-borne applications. And now with the all new  SonaVu acoustic imaging camera you can ‘SEE” the leak in real time making it even easier to scan larger areas.

How to Manage Leaks
It’s not enough to just find leaks. Fixing and documenting savings is a necessary part of the program.

Fortunately SDT have simple and easy to use platforms to track and calculate these costs.

LEAKReporter

A mobile smartphone App available for iOS and Android. LEAKReporter is focused, simple and free. It saves inspectors time and money by documenting leaks in pictures, estimating their cost impact and creating fast comprehensive leak reports. This can be used with the LEAKChecker, SDT200, SDT270 or SDT340.

SonaVu InSights™

Is a web application for creating instant reports of compressed air leak and electrical asset surveys performed with the SonaVu Acoustic Imaging Camera from SDT. Document findings, prioritize repairs, estimate cost impact, eliminate energy waste, and save money with this free application.

Being competitive has never been more important than it is today. Energy costs directly impact your bottom line. There is no easier way to reduce energy waste than to tackle the “low hanging fruit” in your compressed air system.

It doesn’t have to be complicated.

Detect, fix and save money with SDT Ultrasound Solutions.

How to select the right vibration sensor

With so many different types, shapes and sizes to choose from, selecting the right vibration sensors (otherwise known as accelerometers) for your operations can be a challenging task. It is, however, essential. To ensure you specify correctly, there is a number of important factors you need to consider.

Vibration range and sensitivity – The range of vibration varies greatly from operation to operation. You should always specify vibration sensors to measure the maximum vibration range of your specific application. In a standard application (80g range), the sensitivity of a typical vibration sensor is 100mV/g, while in low vibration applications (16g) the sensitivity is 500mV/G.

Vibration frequency – Knowing the frequency span you need to measure is as important as knowing the vibration range. The frequency spans are dictated by the fault frequencies of the fastest-turning component in the machinery being monitored. The frequency span of a slow turning ball mill, for example, will be narrower than that of a high speed fan.

Environmental temperature – After poor and incorrect mounting, the greatest threat to the performance of vibration sensors is the environment. High temperatures can affect the operation of the electronics. However, charge-mode accelerometers are specially designed to work in applications with very high temperatures.

Contact with chemicals or debris – This can reduce the reliability of results and should therefore be considered carefully. To ensure performance and results are unaffected by exposure to chemicals or debris, accelerometers with corrosion and chemical resistant stainless steel bodies should be specified.

Hazardous atmospheres – Hazardous environments are those that contain flammable gasses or vapours, combustible dusts, or ignitable fibres, where even the tiniest spark could cause a fire or explosion. To protect people, machinery and productivity, you need intrinsically safe accelerometers, which are specifically designed for use in hazardous areas. They deliver the same level of performance as their non-intrinsically safe counterparts, but do so by using a lower level of energy.

Immersion in liquid – The average accelerometer isn’t constructed to be waterproof. If your application requires accelerometers to be exposed to liquid, the solution is to specify vibration sensors with integral polyurethane cables. This prevents liquid infiltrating the accelerometer and affecting the electronics – whether the sensor is at minimum sprayed with water or even completely submerged in liquid on a permanent basis.

Exit and profile – The exit and profile of a vibration sensor has minimal impact on performance, but if not considered can become a frustration for those responsible for maintenance. Depending on where the vibration sensor is located, you can choose between a top exit, side exit or low profile connection to allow maintenance engineers easy, safe access.

By taking these factors into consideration you can make the right choice in vibration sensor specification for the requirements of the average application or an industry specific use. If you need further assistance or require advice on special applications, GVS is here to help and can assist you in selecting the ideal vibration sensor.

SonaVu Acoustic Imaging Camera identifies vacuum leak within minutes

What is an Acoustic Imaging Camera?

SonaVu™ is an acoustic imaging camera. Using its 112 ultrasound sensors and optical camera, it can detect sources of airborne ultrasound and transmit them into a visual image on its touch screen.

Defects such as compressed air system leaks, compressed gas system leaks, vacuum leaks, the presence of partial discharge on electrical assets, and failed/working steam traps all create turbulence. And when there is turbulent flow present, there is airborne ultrasound. SonaVu™ makes the superhuman hearing capabilities visible to the human eye.

Using an acoustic imaging camera these defects and failure modes can be visualised and pinpointed from up to 50 meters away. And due to the visualisation capabilities of SonaVu™, it’s really easy to use too as demonstrated in the video below.

With minimal device training, maintenance technicians can confidently inspect their assets for defects, long before they cause unexpected downtime. 

SonaVu™ – Bring Condition Monitoring into focus.
