CW-PMC133系列压力变送器采用具有国际先进水平的进口陶瓷传感器或扩散硅传感器,其中PMC133-A型采用压阻式陶瓷膜片:PMC133-B型采用E H电容式陶瓷传感器:PMC133-C型采用美国GENovaSensor公司扩散硅传感器,再配以高精度电子元件,经严格的工艺过程装配而成,它与目前市场上常规的压力变送器相比.有两个显著不同的技术差别,一是测量元件采用新兴的陶瓷材料,不会对测量介质产生工艺污染.二是测量元件内无中介液体,是完全固定的.介质压力直接作用于陶瓷膜片,使测量膜片产生偏移,从而产生电容量的变化,此变化由与其相连的电子部件检测、放大并转换为标准信号输出。正常的压力使膜片偏移0.025mm;超压时膜片偏移0.1mm,此时测量膜片贴到了陶瓷支架上并受到了保护,避免了损坏.
主要性能指标:
两线制4-20mA输出的品种,标准供电DC24V,负载电阻大于600Ω时,每增加50Ω需增加1V供电,但最高供电极限为DC45V.当需要超过DC24V供电时,输出回路应避免长期工作在零负载电阻状态,必要时可在输出回路中串入电阻以降低输出功率管的功耗.零负载电阻时最底供电电压DC12V
