目前,使用模拟式称重传感器电子汽车衡的接线盒一般分并联与串联两种形式。并联式接线盒是利用调整并联在传感器信号输出端的多圈电位器,以改变传感器的输出电阻达到调整传感器灵敏度的目的。其优点是稳定性较好,调整偏载误差相对容易;缺点是 At present, the use of analog load cell electronic truck junction box generally points in parallel and in series in two forms. Parallel junction box is the use of parallel adjustment in the sensor signal output multi-turn potentiometer to change the output resistance of the sensor to achieve the purpose of adjusting the sensitivity of the sensor. Its advantage is better stability, partial load error adjustment is relatively easy; disadvantage is
