Description：

The CA306 144-306-000-321 is a piezoelectric accelerometer designed for extreme environments, primarily used in high-temperature applications in aerospace and industrial gas turbines. The CA306 piezoelectric sensor has a sensitivity of 50 pC/g, a dynamic measurement range up to 100 g, and a response frequency of 5 to 3000 Hz. In practical use, it requires an IPC70X signal conditioner to convert the output charge signal into a standard current or voltage signal. The CA306 144-306-000-321 piezoelectric accelerometer can operate stably over an ultra-wide extreme temperature range of -55°C to +500°C. The sensor is explosion-proof certified and is also available with an integrated mineral-insulated (MI) cable, protected by a stainless steel braided flexible conduit, effectively enhancing durability and corrosion resistance.
