ABB 3BSE030913R0401 Web tension systems Pressductor PillowBlock load cells
DESCRIPTION
ABB’s Pressductor® PillowBlock load cells are sensitive and accurate yet rugged, reliable and compact. The performace of the Pressductor PillowBlock load cells is unsurpassed for paper mill applications characterized by heavy rolls, high speeds and severe conditions – in some instances they are the only viable option. They can withstand high overloads and vibrations, and operate over a wide range of tensions.
The well-proven Pressductor load cells combined with the tension electronics, offer an easy-to-use/ user-friendly web tension measurement system with superior long term performance leading to higher productivity and product quality and higher profit for the web producer.
Increased process uptime
In a web process running continuously, every minute of production time is precious. Even so, no production line runs without downtime. With Pressductor PillowBlock load cells the risk of web breaks can be reduced to a minimum, thus leaving as much time as possible for real production.
Tighter product tolerances
The ability to produce web to tighter tolerances minimizes the costs associated with nonconforming web. It also increases the web producer’s accessible market to include products with tighter tolerance requirements.
Minimize maintenance
Share the experience, of virtually maintenance-free load cells, with thousands of other PillowBlock users. A robust load cell design with no fragile or ageing components makes this possible. Thanks to its robust design, the PillowBlock load cells work consistently for many years without any need for maintenance, also in the toughest paper mill applications.
Fast access to support and service

You obtain advanced solutions to problems, service and professional consultation through our After Sales Service program. Expert engineers with extensive experience of all types of Force Measurement products are available to assist you through our world-wide network.
The Pressductor difference
Like ABB’s other load cells based on Pressductor Technology, PillowBlock load cells rely on electromagnetic changes in the transducer, not on physical movement, to sense fluctuations in web tension. The Pressductor Technology operating principle provides exceptional improvements in load cell performance characteristics, including reliability (notably absence of drift), durability, repeatability, and wider measurement range.
Machined from a solid block of steel, the load cells are rugged and stiff, affording high overload protection as well as an extended measurement range above the nominal load. And they do not contribute to machine vibration, even at high speeds.
Since the transducer action – the magnetic flux – takes place inside a steel core, environmental factors like dirt or fluids can’t degrade performance and reliability. These stainless steel load cells don’t require any physical seals.
Designers appreciate:
• Remarkably high spring constant
• Wide measurement range
• High reliability
Operators value a load cell with:
• No drift
• No need for recalibration
• No failures
• High reliability
Application hint
• Horizontally measuring load cells are ideal in applications with high tare loads and relatively small tensions, such as paper machines.
• In applications where high overloads can occur in any direction, the high overload tolerance in all directions of ABB’s horizontal PillowBlock load cell adds reliability.
• If no horizontal resultant force is present, mounting the load cell on a slant will give rise to one.
Key advantages:
• Smaller load cell sizes can be specified since the tare weight won’t be a factor
• Inherently sturdier designs are virtually maintenance-free
• No contribution to machine vibration
