    • A conveyor belt scale of the weighbridge type is disclosed having a frame mountable above a run of conveyor belt idler, the weighbridge having a pair of weight transfer bars extending from each end of the device to support the entire weight of the weighbridge and conveyor belt, each of the weight transfer bars being cooperatively connected to a load cell apparatus, each pair of load cells at an end of the device is cooperatively connected by a strain gauge disposed to measure deflections of the load cells under the weight and tortional movement of material passing along the conveyor. The apparatus further contains a speed sensor device to measure the speed at which material moves along the conveyor and a programmable computerized integrator apparatus which accepts the information from the strain gauges and from the speed sensor to give a digital readout of an estimated weight and volume of material passing along the weighbridge at any given time.
    • 公开了一种称重桥式传送带秤,其具有可安装在输送带惰轮上方的框架,称重桥具有从该装置的每个端部延伸以支撑称重桥和传送带的整个重量的一对重物传递杆, 每个重物转移杆协同地连接到称重传感器装置,装置一端的每对称重传感器通过应变仪进行协作连接,所述应变仪设置成在通过的材料的重量和弯曲运动下测量称重传感器的挠度 沿输送机。 该装置还包括速度传感器装置,用于测量材料沿输送机移动的速度和可编程计算机化的积分器装置,其接收来自应变计和来自速度传感器的信息,以给出估计的重量和体积的数字读数 材料在任何给定时间沿着称重桥传递。
