目前,常用DDZ-Ⅲ型电动单元组合仪表来组成气体、蒸汽的温度、压力自动补偿系统。系统可由若干台仪表组成,然而在系统中起着至关重要作用的仪表要属乘除器了。由于它的输入变量来自生产中的工艺参数,而输出值又直接反映需求量,因此,系统能否依据气体或蒸汽的温度、压力变化进行自动补偿,这就完全取决于乘除器的工作是否正常且准确无误。一旦
At present, DDZ-Ⅲ-type electric unit instrument commonly used to form gas, steam temperature and pressure automatic compensation system. The system can be composed of several instruments, however, plays an important role in the system instrumentation should be a multiplier and divider. Because of its input variables from the production process parameters, and output values directly reflect the demand, therefore, the system can be based on gas or steam temperature, pressure changes automatically compensate, which depends entirely on whether the work of the multiplier and divider And accurate. once
