PRELIMINARY 34205A ±5 g to ±50 g Triaxial Accelerometer Superior Zero g Bias Stability Low Noise - Wide Bandwidth 5 8 Technical Data* Features and Benefits High Accuracy and Linearity over Wide Temperature Range The voltage output for each axis of the 34205A is directly proportional to the acceleration along that axis. Each DC-coupled output is fully scaled, referenced, and temperature compensated over the entire -40 to +85°C temperature range. CalibrationCertificate Each 34205A is supplied with a calibration certificate listing sensitivity and offset, as well as the on-axis and transverse alignment parameters needed to ensure rapid and efficient system implementation. The alignment data can be used to compensate the measured values to achieve an even higher level of sensor accuracy. Small Size Complete conditioned triaxial accelerometer in less than a cubic inch. uilt-In Power Supply Regulation B Unregulated DC power from +8 to +18 volts is all that is required to measure accelerations on all axes. Suitable for Harsh Environments The 34205A is robust and can be used in harsh environments. The unit is packaged in a rugged aluminum housing and will survive 5000 g powered or unpowered. Warranty These Measurement Specialties accelerometers come with a three-year factory warranty. 34205A Triaxial Analog Accelerometer precisionsensors.meas-spec.com Precisely Measure Real-World Accelerations Measurement Specialties 34205A accelerometer provides the accuracy required by most measurement applications without any compensation. Critical applications requiring higher accuracy can use the alignment data provided on the calibration certificate to compensate for any small residual error. Choose the bandwidth and range options best suited for your application to measure ±5 g, ±10 g, ±20 g, ±25 g, ±30 g, ±40 g, or ±50 g accelerations on each of three axes. Each axial sensor has been tested over the -40 to +85°C temperature range and has a nominal full scale output swing of ±2.25 volts. The zero g output level is nominally +2.5 volts. Precise values for each axis are available on the included calibration certificate. 2236 N.
