摘要: A load transducer includes a hollow body and a movable control element mounted in the body and extending through the body to an external surface of the body so that an external mechanical load can be applied to the control element to move the control element in one direction. Resilient means separate from the control element urges the control element in the opposite direction such that, in use, the control element is displaced by an amount dependent on the magnitude of the applied load. Coupled to the control element is a variable capacitor including a first electrode supported by a first carrier member in which the first carrier member is mounted so that the carrier members are capable of relative sliding movement in a direction perpendicular to a pair of parallel mutually presented surfaces of the electrodes. The carrier members are arranged so that movement of the control element serves to impart said relative sliding movement to the carrier members, whereby the distance between said electrode surfaces varies in accordance with the magnitude of the applied load but said surfaces remain in parallel, spaced relationship so that the capacitance of said capacitor varies with the applied load.
