New Technology for Smaller, Low-Cost Rotary Position Sensors (MFS-31237)
NASA Marshall Space Flight Center developed this technology in effort to reduce the size of microgravity vibration isolation systems. The technology can be configured as a rotary position sensor, similar to conventional resolvers, but it uses a different concept for sensing rotary position. The sensor unit also can incorporate signal conditioning electronics into the housing body to develop the desired output. Benefits include: produces conventional resolver signals, high-quality sensor information, full 360-degree range, small package size at a low cost, low rotary inertia, multiple output capability possible with internal signal-conditioning electronics, continuous, absolute output without discrete jumps like with encoders, electrical redundancy achieved with minimal volume or cost impact. With this many benefits this technology can be used in any rotational measurement application for example: printers, photocopiers, fax machines, electric motors, robotics, medical scanners, antilock brake systems and even industrial manufacturing equipment.
