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。

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
智能差压液位式变送器是一种直接安装在管道或容器上的现场变送器。由于隔离膜片直接与液体介质相接触,无须将正压侧用导压管引出,因此可以测量高温,高粘度,易结晶、易沉淀和强腐蚀等介质的液位、压力和密度,然后将其转换成4-20mADC信号输出。液位变送器广泛应用于河流、地下水位、水库、水塔及容器等场合的液位测量与控制,它是通过测量液体的压力进而换算成液位的一种传感器。
