10 pC/g, ?54 to 650 °C, up to 3700 Hz.
The CA901 piezoelectric accelerometer is a high-quality, high-reliability vibration sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC704 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).
FeaturesDesigned for the long-term measurement of vibration in extreme environments, such as gas turbines and nuclear applicationsVery wide temperature range: ?54 to 650 °COperational as a loose-part monitoring accelerometerAvailable with an integral mineral-insulated (MI) cableCertified for use in potentially explosive atmospheresPARAMETER
