工作原理

    介质压力直接作用于陶瓷片,使测量膜片产生偏移。正常的压力使膜片偏移0.025mm,超压状态也只使膜片偏移0.1mm。此时,测量膜片贴到了陶瓷支架上,避免了损坏。膜片位移产生的电容量,由与其直接连接的电子部件检测,放大和转换为标准信号输出。

本安型压力变送器

    HR-K本安型压力变送器采用本质安全电路,适用于爆炸危险区域,防爆等级Exd ⅡBT4,技术性能指标与普通型压力变送器相同。
    在系统回路中必须采用屏蔽信号电缆,并可靠接地。

安装方式

    HR-K系列压力变送器通常采用管道直接安装方式,建议加装阀门,便于安装、调试和维护。
    当介质温度高于85℃时则需要加装一定长度的引压管,便于冷却介质,否则会造成测量不准甚至损坏变送器。
