智能差压变送器用于防止管道中的介质直接进入变送器里,感压膜片与变送器之间靠注满流体的毛细管连接起来。用于测量液体、气体或蒸汽的液位、密度、压力、以及流量,然后将其转变成4~20 mADC电流信号输出。它可以通过HART通讯协议的手操器相互通讯,进行设定和监控。
差压式变送器适用于下述测控情况:
在石油化工生产过程中,智能差压变送器经常用来与节流装置配合测量液体、蒸汽和气体流量,或用来测量液位、液体分界面及差压等参数。
二、性能规格
零点迁移量
最大正迁移量:测量范围上限值与测量量程之差
最大负迁移量:测量范围下限值
测量范围
测量下限:-100%URL~+100%URL-Span
测量上限:-100%URL+Span~+100%URL
普通型供电电源
变送器供电电源为11VDC-45VDC,带LCD 显示表头时供电电源为15VDC-45VDC,纹波含量小于0.1%,现场运行时,由配电器或稳压电源供电,一般工作电压为24VDC。
负载特性
变送器负载特性为:RL≤(Vs-Vm)V/0.023A式中:RL--最大负载电阻;Vs--供电电源;Vm--无LCD显示表头时为11V,带LCD 显示表头时为15V。HART 通信时负载电阻(含信号接收电阻及信号传输导线电阻)要求230Ω~600Ω。
量程和零位的调整
HART手操器、就地按钮、支持HART协议的通信软件。
响应时间
当变送器的电气阻尼关闭时,变送器对阶跃输入(10%)的响应时间(63%)小于或等于0.4s。
测量对象:液体、蒸汽、气体
工作温度:-40℃~85℃
精度等级:0.1%F.S
量 程 比:100:1
绝缘电阻:>100MΩ(500VDC)
电气阻尼:0.1~16s 可任选
温度影响量:优于0.1%F.S/10℃
供电电源:11~45VDC(不带背光显示)
15~45VDC(带背光显示)
EMC:符合EN 61326-1:2013标准
输出信号:4~20mA(Max 22mA,Min 3.8mA)
通信接口:HART通信
本安性能:EX ia IIC T6智能绝压变送器主要用于测量气体、液体和蒸汽的压力、负压和绝对压力等参数,然后将其转换成4-20mADC信号输出。它可以通过符合HART协议的手操器相互通讯,从而方便了自诊断,测量范围重新设置和自动调零。压力变送器的δ室一侧接受被测绝对压力信号,另一侧被封闭成高真空基准室,它可以测量排气系统、蒸馏塔、蒸发器和结晶器等的绝对压力。
