- Operating temperature: −196 to 700 °C
- Frequency response: 3 to 3700 Hz
- Available with an integral mineral-insulated (MI) cable
- Certified for use in potentially explosive atmospheres
Description
The CA901 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 CA901 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).
Features
- Sensitivity: 10 pC/g (200 g)
- Operating temperature: −196 to 700 °C
- Frequency response: 3 to 3700 Hz
- Operational as a loose-part monitoring accelerometer
- Available with an integral mineral-insulated (MI) cable
- Certified for use in potentially explosive atmospheres
