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).
