    灵敏度线智能补偿功能
     索福达SFD-600XX天天直播体育在线直播、有毒气体变送器

        一般性天天直播体育在线直播、有毒气体变送器显示精度为0.1%,探测显示精度高于行内同类产品。

        剧毒类气体变送器精度为0.01%,探测显示的高精度业内首创(如:TDI气体的量程0-0.05mg/m3、砷化氰气体的量程范围0-0.03mg/m3)。

        采用最新多彩液晶,六色显示。低浓度是为绿色、一段报警时为浅红色、二段报警时大红色、故障报警时为黄色。进入菜单参数修改时炫紫色、进入内部参数选项为蓝色。帮助您迅速判明现场情况。

     三种信号输出:

    A、4-20mA标准电流信号;

    B、一段、二段报警点直流驱动信号(驱动容量DC24V/1A);

    C、Modbus协议、RS485总线通讯信号。

     设备发生故障时,显示屏背景变成黄色,并显示相应代码指示故障种类,方便现场仪表维护及使用。

        基于大多数气体传感器的灵敏度线性会随时间的增加而下降(催化燃烧传感器每月下降1-2%),我们首创的只需要磁棒调试的传感器智能线性补偿技术,大大提高了气体探测的客观性与安全性。

        使用高能磁棒进行调试,避免了开盖、机体按键及遥控调试所带来的受现场环境影响而造成可靠性低、防护防爆性差等缺点。

     其他厂家的天天直播体育在线直播、毒性气体变送器。
     显示进度为1%,探测显示精度一般。
     普通单色显示。
     只能输出一种或两种信号。
     无此功能
     使用遥控器或开盖调试,防爆方面存在隐患。
