About
The DHS 514 Pressure Converter is a piezoelectric transducer specifically engineered for the measurement of acoustic pressures generated by non-aggressive gaseous media. Its primary application is to assess the impact of these pressures on the structural elements of rocket and space technology during the removal stage. The device operates in conjunction with a voltage amplifier to provide accurate readings. Key features of the DHS 514 include high reliability, excellent noise immunity, a normalized output signal, and small dimensions, making it suitable for demanding space-related environments. It is manufactured in accordance with “Regulation 88” and features an explosion protection type classified as “Intrinsically safe electrical circuit,” which is achieved through an intermediate converter. The converter itself consists of a sensitive element housed within a casing, connected to a matching device via a cable jumper. The product has flight qualification.
