Folded loops locate coils with precision: a new method of inductive sensing enables linear, rotational and two-dimensional position sensing at low cost

Article Abstract:

New linear sensor technology enables the sinusoidal loops of a conductor on a printed circuit board to precisely detect the position of resonant coils at low costs. Applications for absolute or incremental detectors include machine tool carriage position detection and electronic board games. The technology tolerates variations, is resistant to EMI problems and meets European Union EMC regulations.

Integral radio cuts costs in sensing

Article Abstract:

Ellison Sensors International has been working for some time on the development of sensors and transducers with straightforward, low-powered digital radio communications built-in. Such equipment has the potential to bring considerable cost savings in process control, and could be used in many other kinds of information devices. Applications would include the oil and gas, chemical and water industries. Ellison now plans an eight channel system with microprocessor-based control and software held in EPROM.
