Tri-Tronics Photocraft Wheel

Uses precision measuring wheels to track and measure the movement of a conveyor belt or a moving web.

Wheel encoders ride directly on the moving material, use a wheel tread having a high coefficient of friction, and have a very low starting torque resulting in virtually no slippage of the wheels on the belt. In addition, the wheels are precision ground with exacting tolerances, versus a roller which has a much larger tolerance, and its circumference seldom translates into an integral number of encoder pulses per unit of linear movement.

Our single and dual wheel encoders offer additional advantages:

Integrated mounting arm for easy installation
Accessories for mounting above or below a conveyor or moving web
Rugged construction for continuous duty in industrial applications
“Anti-Jitter” feature eliminated measuring and tracking problems and the resulting miss-sorts often encountered when a conveyor or web stop or restarts
Circuit protection that eliminates failure caused by the significant levels of static electricity often associated with conveyors
“Programmable” versions that enable selection of various features at installation time, such as the pulses per revolution and the output circuit type, resulting in maximum flexibility with minimum inventory
