Abstract A novel fieldmill used as space electric field sensor is introduced, accompanying with its application. Amplitude and direction of DC electric field are measured with detecting alternating induced charge varying with the rotation of a rotator. Adopting novel mechanical structure and unique circuit, the unexpected influence of space charge and ion current is eliminated to negligible level. This senor is used to detect space electric field ranging lOOV/m to 50000V/m. The experiment of space electric field detection has finished, and satisfying data are got with this sensor.
