Abstract
A pressure sensor for sensing pressure of a fluid includes a tubular housing that has a first capacitor plate segment and a second capacitor plate segment. Each of the first capacitor plate segment and the second capacitor plate segment includes a respective substantially planar inner surface. The pressure sensor also includes an anvil positioned within the tubular housing. The anvil and the tubular housing function as opposite terminals of a variable capacitor. A first capacitor plate side of the anvil and the first capacitor plate segment face each other and have a first gap therebetween. A second capacitor plate side of the anvil and the second capacitor plate segment face each other and have a second gap therebetween. Capacitance of the variable capacitor changes in response to a first change in a size of the first gap and a second change in a size of the second gap.
