ABSTRACT:
The present invention relates to a sensor for sensing orthogonal components of angular velocity of rotation of the sensor about any axis in a plane perpendicular to a reference jet axis within the sensor, wherein a fluid jet is deflected relative to two pairs of electrically resistive, temperature sensitive elements in response to rotation of the sensor, wherein each pair of elements forms the sensing branch of a bridge circuit, the jet deflection causing differential cooling and bridge unbalance which is an indication of the deflection of the fluid jet from the reference jet axis which is in turn an indication of the rate and direction of angular rotation, wherein each pair of elements is disposed in a plane perpendicular to the reference jet axis, each pair sensing an orthogonal component of angular velocity of rotation.
