    • A load sensing unit (16) having an integrated linear mounting portion (25) which can be secured in a load supporting machine, and having a tongue (24), deflectable by a load and a plurality of load sensing gauges (38, 40, 42, 44), secured to the tongue (24), so that two of the gauges can be placed in tension by a load on the tongue, and two of the gauges can be placed in compression by a load on the tongue, electrical connections (46, 48, 50, 52), connecting the gauges so that the gauges in tension are connected in series with the gauges in compression, on opposite sides of a bridge circuit, deflection of the tongue (24) in turn placing two of the gauges in tension, and two of the gauges in compression, and a signal device (90), connected to the bridge circuit to receive signals from the gauges, and being responsive to the signals from the gauges in tension, and signals from the gauges in compression, and to generate load signals proportional thereto, and load carrying apparatus incorporating such sensing units, so as to function as a mobile weight scale.
    • 一种负载感测单元(16),具有集成的线性安装部分(25),其可固定在负载支持机器中,并且具有可被负载偏转的舌部(24)和多个负载感测计(38,40,44) 42,44),固定到舌部(24),使得两个量规能够通过舌头上的负载被张紧,并且两个量规可以被负载压在舌头上,电连接 (46,48,50,52),连接所述量规,使得张紧的量规与压缩的压力表在串联回路的相对侧串联连接,舌部(24)的偏转依次将两个 压力测量仪和压缩仪表中的两个以及连接到桥式电路的信号装置(90),用于接收来自量规的信号,并响应来自拉力仪表的信号,以及来自仪表的信号 压缩,并产生与其成比例的负载信号,以及负载装置 操作这样的感测单元,以便起到移动重量的作用。
