这里介绍的测力系统能给出数字输出,其分辨力为满载时的十万分之一。该系统利用与数字电压表连接的载荷传感器,能测出载荷传感器输出与供电电压固定比例的比率。该系统的温度系数小于士0.001℃/%,6个星期校准的非再现性小于±
The force-measuring system described here gives a digital output with a resolving power of one hundred thousandth of a full load. The system uses a load cell connected to a digital voltmeter to measure a fixed ratio of load cell output to supply voltage. The temperature coefficient of the system is less than ± 0.001 ° C /%. The non-repeatability of calibration for 6 weeks is less than ±
