Title:
DEVICE FOR MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/1992/008111
Kind Code:
A1
Abstract:
A device for measurement in which signals to indicate weight are output from a measuring conveyor (1) having a load cell (5) supporting a conveyor (4) and high frequency components in said weight-indicating signals are removed by digital filters (10, 10A). Taking a length (Lm) of an object (M) to be weighted into account, conditions for separating weight-indicating signals are set in the digital filters (10, 10A), a time required for the object to be transferred to the conveyor (4) is computed, or timing for adjusting the zero-point of the load cell (5) is set. In this way, even when a length (Lm) of the object (M) varies, no trouble occurs in measurement.
