The CE281 piezoelectric accelerometer is a high-quality, high-reliability vibration sensor with a piezoelectric sensing element and attached electronics that provides a current output.
The CE281 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 severe environments, such as gearboxes, compressors, pumps and fansWide temperature range: ?55 to 260 °CHigh frequency response: up to 7000 HzCurrent output (10 µA/g) for signal transmission over long distances: up to 1000 mCertified for use in potentially explosive atmospheresPARAMETER
