Resonant inductive sensing is well suited to measuring the angle of dials. They can form part of a user interface, to deliver precise inputs to electronics. Or they may be part of a machine, for example the register wheels of a mechanical meter.
There is no contact between sensor and targets. This means that the dials and readers may be housed in separate modules. So, for example, a fixed reader can read multiple sets of dials as they move round a production process, and each set of dials can be read by multiple readers at different points in the process.
