    • A method for testing a Coriolis transducer (10) having a mass (14) adapted to vibrate along a vibratory direction, here axis (21), in a resonant structure (47) and undergo a displacement along a sensitive axis (27) perpendicular to the vibration, in response to an angular rate about a mutually perpendicular rate sensing axis (25). In the absence of an angular rate forces are applied on the mass along the direction of vibration and along the sensitive axis, in a predetermined ratio, N. The output of the transducer is measured in response thereto. With such method, a knowm test input angular rate is simulated. Thus the proportionality constant K can be calculated without expensive rate table testing. Further, because the test can be performed with a transducer prior to packaging, electronics integrally formed on the same semiconductor wafer of the mechanical transduction structure can be easily trimmed to provide a desired proportionality constant K.
    • 一种用于测试科里奥利传感器(10)的方法,其具有适于在谐振结构(47)中沿着振动方向(在此为轴线)21振动的质量块(14),并且沿垂直于...的敏感轴线(27)进行位移 响应于围绕相互垂直的速率感测轴线(25)的角速度的振动。 在不存在角速度的情况下,沿着振动方向和沿着敏感轴的质量沿着该预定比率N对质量施加力。响应于此,测量换能器的输出。 通过这种方法,可以模拟一个知识测试输入角速率。 因此,可以在没有昂贵的速率表测试的情况下计算比例常数K. 此外,由于可以在封装之前用换能器进行测试,所以可以容易地修整在机械转导结构的同一半导体晶片上整体形成的电子线以提供期望的比例常数K.

    • A capacitive pick off sensor for a mass flow measurement device is disclosed. The mass flow measurement device includes a flow sensor tube and a drive device for vibrating the flow sensor tube. The capacitive pick off sensor includes at least one conductive plate connectable to a first voltage potential and adapted to be situated adjacent the flow sensor tube which is connected to a second voltage potential. The conductive plate is positioned relative to the flow sensor tube so as to define a gap therebetween. The capacitance between the conductive plate and the flow sensor tube varies due to the relative motion of the conductive plate and the flow sensor tube when the flow sensor tube is vibrated. In other aspects of the present invention, the flow sensor tube is situated in a housing and the drive device is positioned outside the housing for vibrating the flow sensor tube.
