Appendix E PFTL 101 - Designing the Load Cell Installation

E.1 About This Appendix
E.2 Basic Application Considerations
3BSE029380R0101 Rev C
This appendix describes the procedure for designing the load cell installation.
The following sections are included:
•

Basic application considerations

• Designing the load cell installation (step-by-step guide)
• Installation requirements
• Force and wrap gain calculation
– Horizontal mounting
– Inclined mounting
– Single side measurement
• Mounting the load cells
• Technical data
• Drawings
– Cable diagram(s)
– Dimension drawing(s)
– Assembly drawing(s)
Each application has its own individual demands that have to be considered; though a few basic
considerations tend to repeat themselves.
• What type of process is involved (papermaking, converting, etc.)?
Is the environment demanding (temperature, chemicals, etc.)?
• What is the tension measurement purpose; indication or closed loop control?
Are there any specific accuracy demands involved?
• What is the machine design like? Is there the possibility to modify the design,
in order to fit the most suitable load cell, or is the machine design fixed?
• What are the forces acting on the roll like (size and direction)?
Can they be altered by redesign?
If these questions are dealt with thoroughly, the installation is very likely to be successful.
However, the extent to which measurement accuracy is needed, defines the requirements when
designing a load cell installation.
