34201A ±1 g to ±2 g Triaxial Accelerometer Zero g Bias Stability ±2 mg Very Low Noise 110 µg/√Hz Technical Data* Features and Benefits Precision The Measurement Specialties 34201A Triaxial Accelerometer offers precision measurements over the entire -40 to +85°C temperature range with superior bias stability and approximately 100 µg measurement resolution. High Accuracy and Linearity over Wide Temperature Range The voltage output for each axis of the 34201A 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. Our internal temperature compensation routine provides for unrivaled measurement accuracy over varying temperatures. Calibration Certificate Each 34201A 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. Self-Test on Digital Command A TTL-compatible self-test 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 one cubic inch. uilt-In Power Supply Regulation B Unregulated DC power from +8.5 to +36 volts is all that is required to measure accelerations on all axes. Suitable for Harsh Environments The 34201A is robust and can be used in harsh environments. The unit will survive 3500 g powered and unpowered. Warranty These Measurement Specialties accelerometers come with a three-year factory warranty. 34201A Triaxial Analog Accelerometer precisionsensors.meas-spec.com Precisely Measure Real -World Accelerations The Measurement Specialties 34201A accelerometer has each mutually orthogonal axis precisely aligned, typically within ±0.15 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 optional calibration certificate to compensate for any small residual error. Choose the bandwidth and range options best suited for your application to measure ±1 g, ±1.5 g, or ±2 g accelerations on each of three axes. Each axial sensor has been tested over the -40 to +85°C temperature range and has has a nominal full scale output swing of ±2 volts. The zero g output level is nominally +2.5 volts and temperature compensated over the range of -40 to +85°C. Precise values for each axis are available on the included calibration certificate. 2236 N.
