BTG Positioning Systems is proud to announce that it has re-designed most of its RFM positioning sensors. By using a new fabrication process which involves a molded plastic bottom cover and a lightweight aluminum top cover, the sensors have a completely new look and feel. By re-designing these RFM sensors BTG has achieved significant advantages compared to the former design. The sensors weight has been reduced by almost half. In terms of dimensions all sensors have been slimmed down in height drastically. And by using alternative materials the sensors are much more environmentally friendly then before.
