The TR1 Tru-Trac from Encoder Products Company tracks velocity, position, and distance over a wide variety of surfaces. The TR1 is an integrated encoder and spring loaded measuring wheel assembly in one, making it easy-to-use and compact. Its spring-loaded torsion arm offers adjustable torsion load, allowing the TR1 to be mounted in multiple orientations. The threaded shaft on the pivot axis is field reversible and provides mounting access from either side. The TR1 housing is a durable, conductive composite material that eliminates static build up with operating speeds up to 3000 feet per minute.
