(1)合理选用传感器选用传感器要考虑容量、准确度及结构方式。在结构都固定的情况下,当然准确度越高越好。如果某种物料经常在1/2量程甚至1/3量程以下配料,其配料超差概率将大大增加,尤其是像外加剂等称量范围较小的物料秤,因此工地搅拌站应根据配合比选择传感器的容量。 (1) the rational use of sensors Selection of sensors to consider the capacity, accuracy and structure of the way. In the case of a fixed structure, of course, the higher the accuracy the better. If a material is often in the 1/2 range or even 1/3 range below the ingredients, the error rate of the ingredients will greatly increase, especially for weighing scales such as admixtures smaller scale, so the site mixing station should be based on mix Select the capacity of the sensor.
