CA280 piezoelectric accelerometer
Designed for the long-term measurement of vibration in extreme environments, such as gas turbines, gearboxes and compressors
- Operating temperature: −60 to 260 °C
- Frequency response: 0.5 to 6000 Hz
- Available as a sensor only (no integral cable) or with an integral soft-line cable with a flexible stainless steel hose
- Certified for use in potentially explosive atmospheres
Description
The CA280 piezoelectric accelerometer is a vibration sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC707 signal conditioner), is required to convert this charge-based signal into a current or a voltage signal.
The CA280 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).
