TVM20 and TVM35 Field of View Video Measurement Systems

August 16, 2018

Vision Engineering has announced the general availability of its brand new class of TVM Field of View (FOV) video measurement systems. TVM combines a small footprint, with larger system performance and ease of use. Time-saving instant FOV measurements and a moving stage allow larger components to be measured quickly and easily.

The TVM series includes TVM20 and TVM35, with FOV sizes of 20mm and 35mm respectively. Both systems meet rigorous quality assurance applications in electronics, automotive, aerospace, medical and plastics manufacturing: offering rapid and accurate noncontact measurement. Components can be instantly measured within the field of view with a click of the mouse.

Cylindrical, flat, or square components can be instantly measured on the shop floor, offering instant go/no go evaluation. TVM’s small footprint also saves space in the workshop or QC laboratory. Its exceptional ease of use saves on training time and eliminates operator error, making TVM a versatile tool for a range of quality assurance applications.

As with other measurement and inspection systems from Vision Engineering, the TVM systems can be configured to suit specific applications. The fixed-stage FOV system enables instant, accurate measurements of small pressed metal components, turned parts, injection molded plastics, tubes and cables, while the addition of a manually controlled stage extends measurement for larger components up to 200mm x 100mm.

The combination of TVM’s flat field telecentric lens and collimated substage lighting, featuring a new quadrant LED ring light, creates a sharp image of components on the HD monitor and significantly improves video edge detection of complex parts such as threads and valves. TVM works in combination with new software features for instant measurement of wire insulation and screw threads.

TVM’s comprehensive, user-friendly software supports a broad range of applications delivering the precision and clarity that would be expected from expensive high end video measurement systems. The rich suite of features includes simple data import/export, image stitching and reporting facilities.

Built on Vision Engineering’s 60 years of optical inspection and metrology expertise, the TVM 20 and TVM 35 are precision-manufactured in the UK at Vision Engineering’s UK global headquarters.

Commenting on the launch of the TVM20 and TVM35, Mark Curtis, managing director of Vision Engineering said: “TVM is a new class of noncontact measuring system that distils the best parts of our existing metrology range into a compact system delivering fast and flexible measurement to meet the most stringent QC/QA requirements. TVM marks a new era of high value, easy to use field of view metrology tools.”
