    • A tensile force measuring device provides improved linearity and temperature transient behavior. A column load cell (10) in the device is connected at its ends to a first and a second roller chain portion (34, 36), which are in turn connected to the tensile force, to dispose the column load cell to the tensile force between the chain portions. The roller chain portions are connected to the load cell in mutually perpendicular orientation. The load cell has notches (18) formed in the side thereof to equalize the strain thereupon when tensile load is applied. Longitudinal and transverse strain gages (20) are positioned longitudinally intermediate to the notches, and may be on a gaging web (22).
    • 张力测量装置提供改善的线性度和温度瞬态特性。 装置中的柱式称重传感器(10)在其端部连接到第一和第二滚子链条部分(34,36),第二和第二滚子链条部分又与拉力连接,以将塔式称重传感器布置成拉力 在链条部分之间。 滚子链部分以相互垂直的方向连接到测力传感器。 称重传感器在其侧面形成有切口(18),以在施加拉伸载荷时使其上的应变均衡。 纵向和横向应变计(20)位于切口的纵向中间位置,并且可以在测量网(22)上。
