10 pC/g, ?253 to 500 °C, up to 6000 Hz.
The CA134 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 CA134 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 cryogenic applications and gas turbinesVery wide temperature range: ?253 to 500 °CWide frequency response: 0.5 to 6000 HzAvailable as a sensor only (no integral cable), allowing different mineral-insulated (MI) cable assemblies to be used depending on the applicationCertified for use in potentially explosive atmospheres
