Abstract
A capacitance probe sensor device is disclosed which has a probe formed of KYNAR insulated wire spaced from an uninsulated metallic ground electrode. An oscillator and associated capacitance-resistance network connected to the probe serve to provide a linear output voltage proportional to the change of capacitance between the insulated wire and the ground electrode. The capacitance probe sensor device can be used in a number of applications. They include the measurement of water level, the determination of a liquid's flow rate, and the moisture content of soil.
