壓力傳感器LPS，MPS和HPS是專為氫應用（H2）使用而設計的，例如燃料電池，加油站和高壓罐。該產品系列包括三個版本，可測量高達6bar（LPS）和30bar（MPS）的壓力以及高達900bar（HPS）的高壓。因此，這些傳感器可以完美地完成固定式和移動式氫氣系統以及儲罐中的所有測量任務。所有濕潤材料的選擇均符合在氫應用中使用的高標準，因此傳感器可承受燃料電池和氫罐系統的苛刻環境條件，并在其整個使用壽命內提供可靠，精確的測量結果。因此，H2壓力傳感器已通過EC79或HGV 3.1認證。為了在系統中實現LPS的最佳集成，傳感器提供了差分模擬輸出和數字輸出（SENT/LIN）兩類方式的接口可供您選擇。
