Velmex “TA” Measurement System The Velmex “TA” system is specifically designed for the researcher to perform non-contact measurement analysis. Since 1992, the Velmex “TA” system has been the standard of North America’s Dendrological Research Community. The “TA” system is successfully being used for many diverse application such as: • • • • • • Tree ring growth measurements Growth study of mollusks Probe positioning Precision bore camera inspection Material stress analysis Other applications requiring high accuracy non-contact measuring/positioning. This second generation “TA” system introduced in 2013 provides the highest accuracy with increased durability and compactness at an affordable price. The system uses an inductive sensing encoder that combines the accuracy of the optical encoder and the robustness of a magnetic encoder. For more information refer to “Linear and Rotary Encoders” at www.velmexcontrols.com. Velmex’s TA System has been recognized by North America’s Dendrological Research Community. It includes the proven UniSlide Assembly to maneuver the cookie or core under the microscope. With over 775 systems in operation, Velmex is recognized as a global leader providing this valuable resource to further scientific research. System Components The “TA” system consists of the following three main components: 1. UniSlide® dovetail rapid advance screw motion assembly, available in several travel lengths. 2. One micron (0.001mm) resolution linear encoder integrated to the UniSlide assembly. 3. Velmex VRO™ Encoder Readout for connection to the linear encoder and interface serially to a computer for measurement recording/logging. UniSlide Assemblies are renown for their simple, reliable design where precise micron resolution is required. The encoder is affixed to the side of the carriage (moving element), as pictured above, and sends position data to the VRO and a connected computer. Velmex’s VRO Digital Encoder Readout delivers ultra-precise position readouts on one or two axes. Accessories: 1. USB to RS232 Serial Cable 2. VRO-TAB2 remote reset and send remote input module Positioning Systems for Science and Industry Positioning Systems for Science and Industry

Velmex “TA” Measurement System Miscellaneous Requirements Since the knob projects below the base of the UniSlide® it is necessary to mount the UniSlide on a spacer or orient the slide so the knob extends beyond the work surface. Wood, plastic, or some other flat material, 3/4” or thicker, can be used. On the top surface of the slider (moving element) it is suggested a larger work surface be mounted. This will provide the necessary support for cores and cookies. The material suggested is ½” x 10 ½” x 5 ½” PVC plastic. VRO Encoder Readout Configuration for “TA” Systems VRO Front Panel Setup...
