Linear Measurement Solution Encoders

As the term implies, rotary encoders generally provide feedback for rotary motion. However, with the addition of a measuring wheel, gear, or cable-draw assembly, a rotary encoder can also provide feedback for linear displacement or measurement.  EPC offers a line of integrated linear measurement solutions. They’re easy to install and deliver reliable, accurate feedback for applications such as cut-to-length, spooling, length measurement and print registration.

• The TR1 Tru-Trac™ is a versatile solution for tracking velocity, position, or distance over a wide variety of surfaces in almost any application.  An integrated encoder and spring-loaded measuring wheel assembly available in one, the TR1 is both easy-to-use and compact.  Its spring-loaded torsion arm offers adjustable torsion load, allowing the TR1 to be mounted in almost any orientation — even upside-down.  The threaded shaft on the pivot axis is field reversible providing mounting access from either side.  The TR1 housing is a durable, conductive composite material that minimizes static build up.  With operating speeds up to 3000 feet per minute and a wide ­variety of configuration options, it’s easy to see the TR1 Tru-Trac™ is the ideal solution for countless applications.
• Encoder and measuring wheel solution integrated into one compact unit
• Spring-loaded torsion arm makes wheel pressure adjustments a snap
• Easily installed in a vertical, horizontal or upside down orientation
• Operates over a variety of surfaces at speeds up to 3000 feet per minute
• Integrated module simplifies your system design, reducing cost
• The TR2 Tru-Trac™ is a versatile solution for tracking velocity, position, or distance in almost any application and features an integrated encoder with a rack-and-pinion gear assembly.  Using the rack-and-pinion gear system, encoder readings can be obtained with repeatable positioning, providing excellent accuracy.  Racks can be ordered in varying lengths, and with the accessory spacer block, multiple lengths of rack can be joined for easy installation.  The spring-loaded torsion arm provides easily adjustable torsion load, giving the TR2 all the flexibility and maneuverability of the original TR1 Tru-Trac™.  It can be installed in a horizontal, vertical, or upside down position.  The threaded shaft on the TR2’s pivot axis is field reversible, providing mounting access from either side, and the durable conductive composite housing material reduces static build up.
• Encoder with rack-and-pinion gear integrated into one compact unit
• Easily installed in a vertical, horizontal or upside down orientation
• Operates at speeds up to 400 feet per minute
• Spring-loaded torsion arm eliminates gear backlash
• Integrated module simplifies your system design
• The TR3 Heavy Duty Tru-Trac™ is an integrated heavy duty encoder and spring-loaded measuring wheel assembly all in one, easy-to-use, compact unit.  Available in  both single and optional dual-wheel format, the TR3 Heavy Duty Tru-Trac™ is a versatile solution for tracking velocity, position or distance over a wide variety of surfaces in many industrial applications.  Its spring-loaded torsion arm provides a simple-to-adjust torsion load, allowing the TR3 Heavy Duty Tru-Trac™ to be mounted in any orientation, even upside-down.  The TR3 Heavy Duty Tru-Trac™ housing is an all-metal work horse, specifically designed to take on your toughest application environments at operating speeds up to 3000 feet per minute.  Just one look and it’s easy to see the TR3 Heavy Duty Tru-Trac™ is the ideal solution for countless applications.
