About
The Piezoelectric Pressure Pulsation Sensor LH 604 is engineered for the precise measurement of pressure pulsations in both liquid and gaseous media, specifically within the power plants of rocket and space technology. It is compatible with either a charge amplifier or a voltage amplifier for signal processing. The sensor is characterized by its robust noise immunity, high sensitivity, and the stability of its metrological characteristics even when subjected to varying pressure, temperature, and vibration conditions. The product has undergone flight qualification, confirming its suitability for space applications. The sensor itself consists of a sensing element housed within a protective casing, connected via a flexible cable.
