压力传感器LPS,MPS和HPS是专为氢应用(H2)使用而设计的,例如燃料电池,加油站和高压罐。该产品系列包括三个版本,可测量高达6bar(LPS)和30bar(MPS)的压力以及高达900bar(HPS)的高压。因此,这些传感器可以完美地完成固定式和移动式氢气系统以及储罐中的所有测量任务。所有湿润材料的选择均符合在氢应用中使用的高标准,因此传感器可承受燃料电池和氢罐系统的苛刻环境条件,并在其整个使用寿命内提供可靠,精确的测量结果。因此,H2压力传感器已通过EC79或HGV 3.1认证。为了在系统中实现LPS的最佳集成,传感器提供了差分模拟输出和数字输出(SENT/LIN)两类方式的接口可供您选择。
