PRELIMINARY 34207A Triaxial Accelerometer ±10 g to ±70 g Wide Bandwidth to 10 kHz Precision Aligned Technical Data* Features and Benefits Precision Alignment Each axis of the Measurement Specialties 34207A is precision aligned to minimize errors due to axis misalignment or transverse sensitivity. High Accuracy and Linearity over Wide Temperature Range The voltage output for each axis of the 34207A 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. Accuracy is improved by minimizing variations due to temperature and aging effects, resulting in a sensor that is more stable over temperature than piezoelectric or piezoresistive devices. Calibration Certificate Each 34207A is supplied with a calibration certificate listing sensitivity and offset, as well as 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. Self-Test on Digital Command A TTL-compatible self-test low input causes a simulated acceleration to be injected into all three sensors to verify channel integrity. Small Size Complete conditioned triaxial accelerometer in less than a cubic inch. uilt-In Power Supply Regulation B Unregulated DC power from +8.5 to +36 volts is all that is required to measure acceleration and temperature. Suitable for Harsh Environments The 34207A is robust and can be used in harsh environments. The unit will survive 4000 g powered or unpowered. Warranty These Measurement Specialties accelerometers come with a three-year factory warranty. 34207A Triaxial Analog Accelerometers precisionsensors.meas-spec.com Precisely Measure Real -World Accelerations The Measurement Specialties 34207A accelerometer has each mutually orthogonal axis precisely aligned within 0.75 degree of the theoretical ideal. This 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 up to ±70 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 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.
