On the other hand, it is also often possible that two states deliver very similar measured values at a certain frequency and thus can hardly be differentiated, so that a measurement at different frequencies is indicated for this reason alone.
  • the power consumption is consequently increased compared to a single measurement. It can be useful to equip the sensor with at least two coils.
