Detailed data
The use of VC2 type single crystal material in the CA 901 compression mode accelerometer provides an extremely stable instrument.
The transducer is designed for long-term monitoring or development testing. It is fitted with an integral mineral insulated cable (twin conductors) which is terminated with a Lemo or a high-temperature connector from Vibro-Meter.
Designed for the long-term measurement of vibration in extreme environments, such as gas turbines and nuclear applications
1）Operating temperature: −196 to 700 °C
2）Frequency response: 3 to 3700 Hz
3）Available with an integral mineral-insulated (MI) cable
4）Certified for use in potentially explosive atmospheres
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).
