EXCEPTIONAL IMMUNITY TO NOISE AND INTERFERENCE FROM ISM TRANSMITTERS

All bearingless Torquemeters necessarily use unshielded antennae. As a result, any device (including a like Torquemeter) operating at or near their carrier frequency, can cause interference. FCC rules allow Industrial, Scientific and Medical (ISM) devices to generate unlimited energy. Such ISM devices are commonly used for inventory control, parts tracking, controlling personnel access, induction heating, etc. Most Bearingless Torquemeters use an ISM frequency for data transfer. As a result, they are susceptible to interference from other ISM devices. Since FCC rules only allow narrow band (typically ±7 kHz) transmission for unlicensed use, wideband ISM frequency Torquemeters risk violation of FCC regulations. Himmelstein Bearingless Torquemeters use non-ISM frequencies for power and data, have field strengths within FCC rules, powerful 12 pole signal filters and near field (not radiated field) signal transfer.
