NHR-5600B-27/X/14-X/X/X积算仪

NHR-5600系列流量积算控制仪              
 
 
概述
    NHR5600系列流量积算控制仪针对现场温度、压力、流量等各种信号进行采集、显示

、控制、远传、通讯、打印等处理，构成数字采集系统及控制系统，适用于液体、一般

气体、过热蒸汽、饱和蒸汽等的流量积算测量控制。
    双屏LED数码显示，具有极宽的显示测量范围，可显示整五位的瞬时流量测量值、温

度/压力补偿测量值、流量(差压、频率)测量值等，及整十一位的流量累积测量值，

0.2％级测量精度。
    具备36种信号输入功能，可配接各种差压信号(孔板装置)、线性信号(电磁流量

计)及脉冲信号(涡街流量计)，可自由选择多种补偿方式(温度补偿、压力补偿、温

压补偿等)。
    采用查表法进行密度补偿，可全自动对过热蒸汽、饱和蒸汽进行精度*的积算控

制，内置多种流量积算公式，适应各测量场合，带流量系数K自动演算功能。
    简单的容错功能：温度、压力补偿测量信号异常时，用对应的手动设定值进行补偿

运算。
    特殊设计的WDT电路、上电复位电路和断电数据保护电路确保仪表通电运行正常，断

电数据不丢失，断电数据保护不用后备电池，保护时间5年
    可对测量介质进行定量/批量控制(带启动停止清零功能)。
    可带两路模拟量变送输出。
    支持RS485、RS232串行接口，采用标准MODBUS RTU通讯协议。
    仪表可带RS232C打印功能，具有手动、定时、报警打印功能。
    带DC24V馈电输出，为现场变送器配电。
    输入、输出、电源、通讯相互之间采用光电隔离技术。
    参数设定密码锁定，参数设置断电*保存，具备参数恢复出厂设定功能。
