1151LT高精度法兰式压力液位变送器
1151LT高精度法兰式压力液位变送器具有非常丰富的品种,这些品种可以精确地测量微差压至大差压、低压力至高压力、液位、真空度和比重。配合节流装置还可以测量流量,不采用开方器。
法兰式液位变送器,有平法兰和插入式法兰;安装法兰有3#和4#、150#(工作压力为1.89Mpa)和300#(工作压力为4.95Mpa)四种组合可供组合可供用户选用。接液材料除316不锈钢之外,还有哈氏合金、蒙耐尔和钽,可使用于腐蚀性介质中。
1151LT采用金属密封的δ室作为感测元件,使变送器消除机械方式传递力时抗冲击和振动差的问题;消除外部应力和扭矩引起的误差,保证变送器具有较高的稳定性能,同时减小静压(13.79Mpa~31.0Mpa)引起的误差;由于各品种采用大致相同外型尺寸的δ室,使1151整个系列从测量0.12Mpa的微差压型到测量41.37Mpa的压力型,都具有大致相同的外型和重量。
1151型变送器设计精巧,具有防爆和全天候结构。安装、使用和调校都很方便且简单。接线端子和放大线路放置在上部的可密闭的电气腔室中,且彼此相互隔开。所以现场接线时,放大器仍在密封状态下工作。放大线路有反极性保护,防止由于接错而损坏变送器。1151工作时的容积变化量小于0.16毫升,可防止被测介质液柱过大变化,因而可不需为补偿容积变化量而增置冷凝器或液位筒。采用钽、哈氏合金(Hasloy)和蒙乃尔(Monel)合金等防腐性材料,以适应腐蚀性介质的测量。采用集成电路元件和接插式印制电路板,使得故障少,维修方便,减少了备品备件,降低了维修成本。
工作原理
被测介质的压力通过δ室的隔离膜片(LT和带1199的DP/GP远传变送器则是被测压力先经过一次隔离膜片和充满硅油或氟油的全密封的毛细管系统再被传到δ室的隔离膜片)和其中的灌充油传到中心的测量膜片上。除AP型压力变送器,其测量膜片的另一侧是真空基准点外,其它品种的测量膜片的另一侧不是大气压力,就是被测差压的低压侧。测量膜片是一种预张紧的弹性元件,其位移与被测介质的压力成正比,zui大的位移只有0.10mm,测量膜片的位置由它两侧的电容固定极板检测出来。测量膜片和两电容固定极板的差动电容被放大电路线性地转换成4~20mADC的二线制电流信号。
