2-1-3. Connecting Load cells in Parallel 多传感器的并联方式
In some industrial weighing apparatus, two or more load cells may be connected in parallel
to form a hopper scale or track scale. The manner of connection is shown below. Parallel
connection can simply be made by using the optionally avai
lable B410 (summing box for
4-point multi load cell). 在许多工业称重系统中，如料斗秤、轨道衡等，常常将 2 个以上的传
感器并联使用， 连接方式如下图。
可采用各种接线盒， B410
如
（可将 4 各传感器信号累加）

The group of "n" parallel load cells
viewed from this device side can be
regarded as a unit load cell the rated
capacity of which is multiplied by "n"
and the sensitivity of which is
unchanged. The averaging resistance (R)
should be 300
–
500
Ω
, equal in relative
ratio and excellent in temperature
coefficient. No averaging resistance is
needed if load cells with consideration
for parallel connection are used.
接线盒并联“n”个传感器可视为具有
相同的灵敏度单个传感器额定容量的
“n”
倍总和。 传感器的平均电阻 （R） ，
温度系数相当或更好，阻值为 300 –
500Ω，
无需再并联电阻进行并联连接。
0切记事项
When connecting several load cells in parallel, load cell capacity should be higher than
expected load to compensate for mechanical shock or eccentric loading.
多传感器并联使用时，传感器容量必须高于预期的载荷量程，避免机械振动或偏载造
成的影响。
