About
The DHS 517 Pressure Converter is a high-reliability piezoelectric transducer specifically engineered for measuring sound pressure of non-aggressive gaseous media acting on structural elements of rocket and space technology during the removal phase. It operates in conjunction with a charge amplifier and features vibration compensation. The device is constructed according to “Regulation 98” and consists of a sensor housed within a casing, a flexible cable, and a connector. Its explosion protection type is “Intrinsically safe electrical circuit,” which is achieved through an intermediate converter. The product is flight qualified, indicating its suitability for space applications.
