100 pC/g, ?55 to 260 °C, up to 5000 Hz.
The CA202 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 CA202 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 heavy-duty gas turbines and steam turbinesVery high sensitivity: 100 pC/gWide frequency response: 0.5 to 5000 HzAvailable with an integral soft-line cable with a flexible stainless steel hoseCertified for use in potentially explosive atmospheresPARAMETER
