A force sensing device especially suitable for use in an accelerometer or a pressure transducer, depending upon its particular design. This device includes at least one and preferably two adjacent and parallel, elongated vibratable tines and means for vibrating the tines back and forth in a direction normal to their axes of elongation. These tines are supported for vibration by an arrangement including an array of interconnected links and mounting means adapted to be connected to an external member capable of applying a variable external force to the support arrangement along an axis normal to the axes of elongation of the tines. The support arrangement is configured so as to apply to the tines its own internal force in response to and varying with the external force in a way which causes the tines to vibrate at a frequency that varies with the magnitude of the internal force and therefore the external force. In this way, the vibrating frequency of either or both tines can be sensed for determining therefrom the magnitude of the external force applied to the support arrangement.
