Es-Trac 2000 Infrared Non-contact Felt Guide System

The Es-Trac 2000 edge tracking system is one of the most advanced non-contacting measurement and guiding system for felts and fabrics. It can be placed into any part of the machine, even where extreme heat and humidity demand special requirements for equipment. Originally developed for pulp and paper applications, these systems can also be used on machines for the the production of photographic film, Kevlar, fibre-glass roofing material, or any device requiring edge tracking and control.
