Title:
LOAD MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/084662
Kind Code:
A1
Abstract:
Provided is a high-precision load measuring apparatus having an expanded measurement range.
A load section (13) is arranged on one end of a long and narrow beam member (12). A supporting member (11) supports the beam member (12) on the beam member (12) side closer to the other end than the load section (13). A displacement sensor (14) is composed of a capacitive sensor and is arranged to measure the displacement of the load section (13). The beam member (12) has a pair of long and narrow board-like leg sections (26), which are arranged in parallel with a space therebetween in the thickness direction, and a connecting section (25) which connects the end sections of the board-like leg sections (26) on the side of the load section (13). The beam member (12) is supported by the supporting member (11) such that the distance between the position where the beam member is supported by the supporting member (11) and the load section (13) can be varied. Each of the board-like leg sections (26) has a slot (28), which is composed of a long and narrow hole arranged in the length direction, in the center section in the width direction.
