(51)    International  Classification   G01P 15/00 (2006.01)

(54)    Title

Convective accelerometer

(57)    Abstract

A convective accelerometer capable of measuring linear or angular acceleration, velocity, or angle of inclination is provided. The accelerometer comprises sensing elements that are sensitive to convection located inside a scaled housing containing a liquid agent. Applied external acceleration causes forced convection of the liquid agent, which produces variations in an electric current produced by the sensing elements that are proportional to the applied acceleration or angle of inclination. The accelerometer has a small size, extremely wide frequency and dynamic ranges, high sensitivity, simple design and is suitable for mass production. The device has a wide range of application, such as stabilization and control systems, homeland security, and oil exploration.
