前言 量程是仪表本身的一项技术指标,对于数字仪表来说,量程的扩展大多采用衰减被测信号的办法。但是对用于不同吨位的应变计式重量传感器的数字仪表,由于不同吨位的重量传感器在承受其额定负荷时产生的满刻度输出信号是一样的(例如12mv),这就要求仪器在输入信号相同时,有各种不同的符合传感器额定负荷的指示值。在同一数量级的数字仪表中,虽然也能采用改变计数脉冲的当量值和量纲符号的办法来扩展量程,
Foreword Measuring range is a technical indicator of the instrument itself, for digital instruments, the expansion of the range are mostly used to attenuate the measured signal approach. However, for digital gauges used with strain gage weight sensors of different tonnage, since the full scale output signals generated by load cells of different tonnage at their rated load are the same (for example, 12 mv), this requires that the instrument output signals At the same time, there are different kinds of indication values that meet the load rating of the sensor. In the same order of magnitude digital instruments, although it can also be used to change the count pulse equivalent size and dimension symbols to expand the range,
