The Electric Encoder technology is based on variable capacitance, which has been considered sensitive to temperature, moisture, noise pickup, etc. How can it claim the opposite?
Some variable capacitance sensors are indeed quite sensitive to one or more of the above. However the Electric Encoder breakthrough which was made in the context of defense applications has demonstrated the opposite and its superiority has been demonstrated in a wide range of applications besides defense (see our custom encoders). It is covered by several basic patents and relies on a continuous development effort since 1994.
