Tilt sensor based on three electrodes dielectric liquid capacitive sensor
This paper presents a design, fabrication and characterization of a
low-cost capacitive tilt sensor. The proposed sensor consists of a
three-electrode capacitor, which contains two-phase of the air and
liquid as the dielectric media. The three electrodes hold a plastic tube
and the tube is positioned on a printed circuit board (PCB) which
consists of a 127 kHz sine wave generator, a pre-Amplifier, a rectifier
and a low pass filter. The proposed sensor structure can measure tilt
angles in the rage of 0° to 75°, where the linear relationship between
the angle to be measured and the output signal was observed in the range
of 0° to 50°. The sensitivity and resolution of the sensor are measured
to be 40mV/degree and 0.5 degree, respectively.
