The system can overcome the antenna effect of the capacitance probe through the circuit processing technology, and can still get the dynamic range of more than 250mm in the environment with large amount of RF interference.
The measurement accuracy of the system is inversely proportional to the distance, that is, the closer the distance is, the higher the measurement accuracy.
The system has a typical error of 1mm at 140mm.
The number of probe can be extended as required. There is no requirement for the spacing between the probes, the dynamic range and the measurement accuracy will not be affected even if the probe is tightly arranged.
We use the synchronous measurement technology, which has the characteristics of high update rate and the update speed is independent of the number of probes.
No harm to the human body.
The use of low frequency, low field and low voltage, dose not produce harmful ionizing radiation or microwave radiation, and there is no risk of electric shock.
