PULP & PAPER: TENSION, CRANE and PROCESS
BLH Nobel is a leading vendor of advanced measurement equipment for the pulp and paper industry. Throughout the years, we have developed a deep knowledge and understanding of the process challenges facing pulp and paper manufacturers. You can be confident that we can provide the best solutions to help you increase your productivity and efficiency.
Higher Performance – Less Maintenance
Our precision web tension measurement allows paper machines to operate at higher speed with less downtime, meeting your targets when it comes to productivity, functionality and quality.
Our transducers and instruments are designed for easy installation and use, and provide excellent performance in harsh process environments. Providing customized solutions, special load cells and application specific software is not just an option — it is standard procedure with us.
Complete Solutions for Your Paper Machine
Our web tension systems comprise off-the-shelf standard modules and electronics, as well as customized systems. We design force measurement modules according to the customers’ mechanical requirements and forces, ranging in size from just a few Newtons to mega-Newtons. The combination of digital signal amplifiers and stable force transducers means that our systems can handle anything from applications with a low tare and large forces, to those with a large tare and small forces.
The Unique FMU Web Tension Unit
The FMU consists of two precision load cells, a load plate that carries the pillow block, and a base plate that mounts to the machine support. Because the load cells are cylindrical, they can be rotated to measure in the direction of the exact resultant force. Measuring the resultant force assures the highest possible accuracy and eliminates wrap angle restrictions. The high ingress protection of the FMU makes it suitable for all sections of the paper machine.
The G4 Multichannel Instrument
The BLH Nobel G4 instrument offers high speed and high performance, it is a modular instrument, which allows multichannel and synchronous measurement. The multichannel G4 has synchronized samplings of all channels, which enables true measurement that is not affected by severe vibration and shock. It is available with Ethernet IP and other communication interfaces.
Low Profile Web Tension unit
The Z1P is a low profile unit that consists of one single-unit load measuring plate. It has two separate outputs and in different configurations, the unit can be used for both horizontal and vertical force measurement. The low profile unit fits easily into existing SNL bearing housing. The high quality of the Z1P assures no mechanical failure before bearing housing break load. Its stainless steel construction and high ingress protection makes it suitable in harsh environments.
KIS Load Cell Shaft Installation
Our high accuracy load cells are insensitive to side load. Replacing the shaft in a roller with internal bearing by a KIS load cell to measure the force caused by the tension in the paper during production. Since the load cell can be rotated, the full resultant force can be measured. Using KIS as a shaft, we can deliver a wide range up to 500 kN and measuring range 1-100 % of nominal range. The measurement is ideally placed in neutral axis and requires very limited space.
Built to Withstand Heat and Steam
We meet the highest requirements for temperature resistance by high-temperature load cells that are designed for a temperatures range of up to +150°C. We use special mounting kits to prevent heat transfer to the load cells and sheet metal covers to keep radiant heat away.
By a special design of the load cells and the cable glands as well as a filling of the load cell cavities, we achieve an extremely high protection against water and steam penetration. Paired with the use of chemical resistant cables BLH Nobel batching and process weighing equipment for high-temperature environments in pulp and paper applications guarantee a long and trouble free operation of your weighing systems.
