ABSTRACT:
A device used in an apparatus, such as weigher, pressure gauge or the like, for essentially measuring a force, which utilizes a flexural member of elastic material for detecting the force by converting its deflection or strain caused by application of the force into an electric signal, and adapted to compensate for measurement error caused by a time-dependent change in the detection output as a result of creep and/or stress reluxation of the flexural member by removing error components by an electric circuit constructed in accordance with a principle of digital filter.
