Lineer measuring


   Welcome to our electronic rulers page.

Linear ruler technology has been used in industrial automation machine systems for a long time.

   It is basically divided into 2 main groups;

1- Analogue linear electronic scales; Due to their mechanical hardware structure, they are model devices that we can read with a silver-copper alloy nozzle on a fiber carbon alloy tape band. Unlike digital-based scales with glass scales, the magnetic scale technology we use has to "contact" to provide precise linear measurement. This is due to the manufacturing and working form we mentioned above. It is more likely to wear and deform over time. Ultimately, friction causes corrosion, no matter how durable the material is.

2- Digital linear rulers; Digital magnetic tape measuring systems consist of a linear magnetic material and a read head that is fed onto the magnetic tape without contact. This measuring principle is permanently wear-free, very robust and provides the highest resolutions down to 0.2 micron. Thus, our system works independently of dirt, dust, dirt, oil or coolant in the environment. Since the digital display is magnetic, its accuracy is not affected by the negative effects of environmental factors and the adhesion of coolants. The scale is made of metal, so it is extremely resistant to vibrations and impacts.
Electronic devices integrated in the sensor head convert the sinusoidal signal from the magnetic sensor head to HTL or TTL signal. Different signals (A, / A, B, / B, Z, / Z) can then be read with any standard control unit and optionally transferred to 3rd party displays.

   Digital linear rulers are particularly suitable for controlled tooling machines such as milling machines, mills or lathes. On the other hand, other potential applications for many industries are industrial robot systems or precision applications in XY position tables. Sold with a rod end bearing guide rod and other screws etc for easy mounting.

Are the digital readings of all linear sensors the same?

   Many linear measuring systems are based on optical principles. A light source and photo-detector are directed along a glass scale to "read" the overlapping patterns of light shining through or reflected from the grating on the glass. Output signals can be in the form of a square wave pulse or PWM.

   Carbon-based reading methods are not like other pulsed or pulsed signals due to the nature of the incoming signals. Depending on their manufacture, they either give a direct analog value or act like conventional potentiometers and change their resistance.

   As a result, the device model that can read each ruler model is different. While digital linear scales can read models with fast counter reading, Analog scales can be read by devices that accept analog inputs. If you have a PLC system, at this point, it is useful to check which input types your related device has and to choose a product accordingly.

   Can we say that linear rulers = linear potentiometers? Yes, the analog linear scales we mentioned in the 1st item above can be called linear potentiometers.

 Which one should I use ?

Yes, you probably haven't read the above explanations.

> The biggest advantage of digital rulers is that they are "contactless". In other words, since there is no friction during reading, its life is very long. But if the power is cut off, it cannot memorize its position. (This is valid for places where the mechanism can be moved manually, not on machines such as lathes etc.)

> The biggest advantage of linear potentiometers is that they keep the position information mechanically, not electrically, even if the energy is cut off or moved freely (absolute). On the other hand, their lifetime is limited due to mechanical friction.

 - Measuring precision ;

For linear potentiometers, the resolution level depends on the device reading it (how many bits?).

In digital rulers, on the other hand, the resolution accuracy depends on the strip being read (0,05mm)

Reading speeds also depend on the reader device, not the rulers.

Friends, you can access these devices under the heading Ruler reading devices.

   > Supply voltages, output types, input types, operating models are explained in detail on each model's own page, and there are user manuals.

 Note: Like all our products on our website, our electronic rulers are products for use in machines for the industrial automation sector. It has been produced with galvanic isolation for potential sources of interference, such as frequency drivers, power supplies, induction motors of various sizes, located in the same room.
