Welcome to our offline blog. Today you will find some useful information about optical and laser levels and what are the differences between them. Remember that detailed technical specifications of the levels can be found on our website in the extended description. Our store allows you to view all parameters, as well as photos in high quality.
In the article, you will also learn what to look for and where the difference in the prices of similar devices comes from.
Let's start with what a laser level is?
It is a device used to measure height differences in the field and to set levels. Professional nomenclature of this activity is "levelling". Most often, we can see these devices in the hands of surveyors, but not only. They are also willingly used during earthworks and road works. New levels, in combination with machines, allow for the automation of work. An example of such an advanced system is the Nivel System NL610 Digital with the LS-B110 machine control sensor.
What types of leveling instruments do we have?
We distinguish three main types of levelling equipment: optical, code and laser.
Optical instruments: are basic devices for measuring height differences and levels. The classic levels are built, as the name suggests, from the optical elements on which the accuracy of measurements depends. A lot also depends on the tripod and the levelling rod, and of course on the handling skills themselves. If you think about choosing an optical leveller, it is worth considering where we will use it. In the case of small investments, a standard optical magnification will suffice, but if we work in larger areas, it is worth considering buying equipment with greater magnification.
Code instruments (electronic levels): They have an advanced measurement system in comparison with classical devices, thanks to the use of special coding chips and dedicated software. Measurement with these devices becomes faster and more accurate. It is worth noting that the use of such instruments significantly eliminates the risk of reading errors. In the case of this type of levels, it is worth paying attention to the computing power of the chosen device, the software and therefore the possibilities of measurements. An important element is also the patch, which will also depend on the accuracy of data reading. It is worth asking about patches made of fibreglass. An example of the leveller described above can be used by the Topcon 2LS ORION + electronic level.
Laser instruments (rotating levels): they are precise and modern terrain measuring devices that can operate both horizontally and vertically. Their main advantage is increased accuracy, but also that they can work in severe weather conditions. They differ from other devices in that they are equipped with a rotating laser so that only one person can take measurements. One should also pay attention to the self-levelling of laser instruments. The name of the module responsible for this activity is the compensator. Laser technology in almost all areas of life is becoming the leading. Is it the same for levellers? More and more companies are choosing laser devices.
Elements to pay attention to
About optical levels:
- Accuracy of measurement - this is a very important parameter that allows you to assess the quality of the purchased device.
- Magnification - in optical levels it is an important parameter, thanks to which we can choose the right equipment for the scope of works
- Immunity class
- Kit contents
About laser levels:
- The colour of the laser beam - red standard or green, which works perfectly in more sunny places
- Working time on one charge - it is worth investing in instruments with efficient batteries
- The range of the laser device - like in the case of optical levels - tells us which range of terrain can be measured from one position. You can purchase a unique sensor that will increase the range of the device.
- Immunity class
- Kit contents
Work in severe weather conditions
The weather is important for measurements. In the event of bad weather, it is worth waiting for a better aura. This mainly applies to people who opt for optical devices.
We also recommend devices with IP66 protection class (protection against strong water jets) or similar that can work in very severe weather conditions. Levels with high resistance to water, dust, are useful for all those who work mainly outside and can not afford the delays associated with changing aura.
Each available device on our website has full characteristics. Nevertheless, we encourage you to contact our specialists who will be happy to advise you, explain all the differences in detail and answer the questions.
