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

ABB provides customers with superior distinctive  after sales service that really differentiates from  the competition. 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
