Heavy load encoder: the high-precision heavyweight champion

Baum heavy load encoder inherits the groundbreaking heavy load technology of the original hbner Berlin. More than half a century ago, hobnablin developed this kind of particularly reliable and robust rotary encoder. Since then, this kind of encoder has been widely used in various applications where working conditions are harsh and error free. Then, what are the essential differences between heavy-duty encoder and ordinary encoder? What options do they offer users

dock cranes load and unload thousands of tons of goods every day; Mining companies use a transportation system with a total length of several kilometers to transport ores weighing up to 1000 tons; Elevators carry thousands of passengers every day; Automobile manufacturers use automatic production lines to transport vehicles at different assembly stages; The lifting bridge with a total weight of thousands of tons can carry multiple trains at the same time, and take off and land many times a day for ships to pass. Such scenes are countless, which constitute a grand picture of the application of heavy-duty encoder. At any time, heavy-duty encoder must reliably complete arduous tasks under bad working conditions for a long time

the term heavy load has been closely related to hobnoblin since it developed the rotary encoder representing the highest standard in the 1950s. Since then, hobnablin (now a brand of the sensor expert Baum group) has continuously improved its products and has always been regarded as an expert in the field of heavy-duty encoders. However, when we talk about overloaded encoders, what are we talking about? After all, this term is not protected by law, and there is no standard to regulate it. In this way, heavy load only means durability. This may also be why some people think that the heavy-duty encoder is just a thick shell with rust prevention function. In fact, it is possible for this technology to lead to market consumption, and the meaning of the transitional language is far more than this

what kind of encoder can be called a heavy-duty encoder

for baomeng, heavy haul technology provides all-round performance guarantee. First of all, this means that even under the worst working conditions, this encoder will never disappoint users. Secondly, even in the long-term use process, the accuracy of these heavyweight players will not be lost to the lightweight rotary encoder. Baomeng heavy-duty encoder meets the above requirements because of the following four characteristics:

high precision: the rotary encoder must provide reliable signals so that users can accurately control the driving device and generator. The equipment control system uses these signals for speed monitoring of the driving device or position feedback of mechanical components. These signals are the only way for the controller to obtain speed information and intervene in time, for example, when the driving device exceeds or does not reach the set speed range. Because the mechanical equipment and systems are usually very large (such as dock cranes, bucket wheel excavators, rolling mills, garbage crushers, etc.), people may mistakenly think that these equipment do not need too high accuracy. However, this is not the case. Especially when handling heavy objects, it requires a lot of force (such as loading and unloading containers weighing several tons). Even a small measurement error may lead to a series of serious consequences

robustness: the heavy-duty encoder must be strong enough to withstand violent impact, vibration and external forces acting on the encoder shaft for many years. After all, the replacement cost of the encoder is very high, not because the encoder itself is expensive, but because the installation position of the encoder is difficult to access, and the whole system must be shut down when replacing. The heavy-duty encoder has the following features: wide clearance and large-size bearings at both ends, which can compensate radial and axial loads; Solid thick wall shell; Anti shock and anti vibration, providing lasting protection for internal components

tightness: heavy-duty encoders are usually installed in dusty, humid or polluted environments, so the encoder housing must have good tightness, especially in key positions such as shafts and electrical interfaces. In addition, since the encoder may be in contact with chemicals or seawater, it is necessary to use appropriate housing materials and coatings to achieve excellent corrosion resistance

electrical stability: the heavy-duty encoder must have the ability to resist electromagnetic interference. The magnetic field is usually generated by unshielded cables laid nearby, which is very common in many applications. Without proper shielding measures, the electronic components in the encoder may be damaged or send wrong measurement signals. In addition, the potential difference inside the bearing will form shaft current, which may ignite the bearing lubricating oil and cause bearing damage. In view of the above reasons, the electronic components inside the heavy-duty encoder must be electrically isolated from the operating environment

absolute value or incremental encoder: beyond the standard

as mentioned above, heavy-duty encoder has a wide range of applications. Therefore, baomeng heavy-duty product portfolio is also quite rich, including various types of incremental or absolute value encoders. Hog 10/POG 10 series are benchmark products in incremental heavy-duty encoder. As shown in the following two cases, hog10 heavy-duty encoder has more unique characteristics of Baumer products, which can significantly improve the installation accuracy:

heavy-duty encoder is usually installed in a harsh working environment, surrounded by dust, moisture and chemicals, so it is necessary to set strong protective seals. However, all kinds of seals are different: the reason why hog 10 provides a variety of seal designs is to provide the best protection for the encoder under various working conditions, including oily, humid or dusty environment, marine and tropical climate, cement plant or other harsh environment. For example, the seal is very reliable, can withstand the impact of various thick and fine solid particles, and has excellent long-term wear resistance. In addition, the seal will not generate friction, which effectively prevents any loss of performance. This seal design is the most efficient and consumes less energy at high speeds

since heavy-duty encoders are generally installed in large equipment, their signal transmission distance is usually not less than 100 meters. Therefore, Baum attaches great importance to the signal quality of the encoder, and uses short-circuit proof power transistors to achieve high-power output. Among them, the signal transmission distance of some products can even reach 550 meters. If a longer transmission distance is required, optical cables can also be used to realize noise free signal transmission up to 1.5 kilometers

similarly, Baum's absolute value heavy-duty encoder (such as HMG 10/PMG 10) also has special functions beyond the standard encoder, such as outputting accurate position signals through PROFINET interface. Generally, in addition to absolute position information, incremental signals are also required to output speed. The bio based materials have been successfully used for lightweight feedback, so the absolute value heavy-duty encoder will output incremental position signals through serial digital interfaces such as SSI or fieldbus, such as HTL or TTL. Some models of products can even integrate overspeed switches to provide limit speed information through switching value output

flexible solutions for various applications

the encoder supports a variety of installation schemes, no matter whether it is hollow shaft design (through hole or blind hole), tapered hole design, or solid shaft design with optional European flange B10. If necessary, the heavy-duty encoder, overspeed switch and tachogenerator can be combined into a solid unit, which not only saves installation space, but also can measure all kinds of output signals at the same time on the same transmission shaft. Under extremely harsh working conditions such as coal dust, corrosive air or high temperature in the steel plant, baomeng large encoder hog 16/22/28 can be used to monitor the limit speed of the transmission shaft

baomeng's heavy-duty encoder products are very rich. Interested buyers had better consult our experts first to determine which encoder is most suitable for your application. No matter which product you choose in the end, you will benefit from the high accuracy and durability of baomeng heavy-duty encoder, which respects the independence, sovereignty and territory of Maldives
