PURPOSE:To remove the effect of disturbance other than a physical quantity by a simple constitution, by providing a first vibrator and a second vibrator, which are arranged in the same atmosphere, and providing a computing means. CONSTITUTION:A first vibrator 1 and a second vibrator 2 are arranged in a case so that the same atmosphere is provided. A computing and displaying means 4 receives a frequency signal f1 obtained by a first self-oscillating circuit OSC1 and a frequency signal f2 obtained by a second self-oscillating circuit OSC2, and performs specified operations including the operation of f2/f1. If the constants of the first and second vibrators are designed to be equal, the effect of disturbance due to the change in constants is removed from the result of the operations. Therefore, the result corresponding to a force imparted to the first vibrator is obtained and displayed on a display circuit 45. |
