13201A Uniaxial ±1 g to ±2 g Accelerometers Zero g Bias Stability ±2 mg Very Low Noise 110 µg/√Hz 23201A Biaxial C 1A 1 3 2 08 Technical Data* Features and Benefits Precision These Measurement Specialties accelerometers offer 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 the 13201A and 23201A is directly proportional to the acceleration along the axis. The DC-coupled output is fully scaled, referenced and temperature compensated over the entire -40 to +85°C temperature range. Optional internal temperature compensation provides unrivaled measurement accuracy over varying temperatures. Calibration Certificate Each 13201A and 23201A 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. Increased offset compensation can be obtained with Option C002. 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 accelerometer in approximately one cubic inch volume. 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. Reverse power voltages of up to -80 V can be withstood indefinitely. Transients of +80 V for 550 ms compatible with MIL-STD-704A can be withstood with full operation. Easy Installation A built-in terminal block or cable with 9-pin connector simplifies wiring. Tapped holes on bottom and back simplify horizontal or vertical mounting. Suitable for Harsh Environments These accelerometers are robust and can be used in harsh environments. The unit will survive 3500 g powered and unpowered. Simplify Acceleration Measurements Measurement Specialties 13201A and 23201A accelerometers have either one or two orthogonal axes and a temperature sensor in a small, rugged package. The small size and built-in power regulation allow them to fit in most applications without any external circuitry or conditioning. Choose the bandwidth and range options best suited for your application to measure ±1 g, ±1.5 g, or ±2 g accelerations on one or two axes. Each axial sensor has been tested over the -40 to +85°C temperature range. Each axis has a nominal full scale output swing of ±2 Volts from the zero-g output level of nominally +2.5 Volts. Precise values for each axis are provided on the calibration certificate included with each sensor. Warranty These Measurement Specialties accelerometers come with a three-year factory warranty. 13201A.23201A Analog Accelerometer precisionsensors.meas-spec.com 2236 N.
