  以下是相关网友提问:

  1、如何辨别罗斯蒙特压力/差压变送器的真伪?

  纯假的还好辨别的,要是有个真的对比一眼就看出来了。但是,这种假的很少的。有一种是回收的的东西回去翻新,也就是说一模一样。跟一样,这个很难辨别。只有用了一段时间才能感觉出来。建议你通过正规渠道购买,不要一个劲的找最便宜的,假的还没有那么泛滥。

  2、罗斯蒙特压力变送器多少钱?

  有参数吗?最好提供仪表数据表,这种都有设计院的设计数据表的,如果是维修的话,提供原来用的压力变送器的铭牌照片。这样就会更准确。

  3、罗斯蒙特压力变送器测量值比E H压力变送器高一些?

 

  你这种情况需要拿一个标准表来检验到底是那块表测量值不对,一般智能变送器不会测量不准的,你着重检查设置上限和下限是否两块表是一致的,还有两块表的零位是否正常。

  4、罗斯蒙特3051d压力变送器怎么样?

  压力变送器(pressure transmitter)是指以输出为标准信号的压力传感器,是一种接受压力变量按比例转换为标准输出信号的仪表。它能将测压元件传感器感受到的气体、液体等物理压力参数转变成标准的电信号(如4~20mADC等),以供给指示报警仪、记录仪、调节器等二次仪表进行测量、指示和过程调节。
