Charge-Output Type Piezoelectric Acceleration Sensor with High-Temperature 260°C and 500g Range for Vibration Monitoring

The CA280 144-280-000-235 is a charge-output type piezoelectric acceleration sensor designed for monitoring the long-term vibration status of equipment operating in extreme environments. Typical applications include heavy industrial machinery such as gas turbines, gearboxes, and compressors.

This model does not contain an integrated circuit and outputs a high-impedance charge signal. In practical use, it must be paired with an external charge amplifier to convert the charge signal into a conventional current or voltage signal, enabling downstream data acquisition systems to read and analyze the measurement.

The CA280 144-280-000-235 offers outstanding environmental adaptability. Its operating temperature range spans from −60 °C to 260 °C, and its frequency response range is from 0.5 Hz to 6000 Hz. With a sensitivity of 100 pC/g and a measurement range of up to 500 g, these physical specifications enable it to handle high-temperature and intense-vibration conditions with ease.
