IEEE Std 1293-2018 pdf download – IEEE Standard Specification Format Guide and Test Procedure for L inear Single-Axis, Nongyroscopic Acce lerometers .
This specification format guide and test procedure standard applies to force-rebalance accelerometers (pendulous or translational proof mass), vibrating beam accelerometers (V BAs), and micromechanical accelerometers (see 5.1). All acelerometers have biases, scale factors, misalignments, nonlinearities, noise characteristics, and other parameters. Many of the specification requirements and verification test methods for these parameters; their stabilities; their temperature, magnetic, and other sensitivities; the accelerometer behavior through and across vibration, shock, and other environments; and the accelerometer lifetime and reliability are independent of the accelerometer type. Requirements and tests that are specific to a particular accelerometer type are described separately. Only the clauses applicable to the given accelerometer type should be used. This specification is not intended to define requirements for the pendulous integrating gyroscopic accelerometer (PIGA) or for the specific force integrating receiver (SFIR). These high-precision single degree-of-freedom (DOF) accelerometers use gyroscopic precessional torque to rebalance the specific force effect of nongravitational acceleration acting on a pendulous proof mass on the gyro float. This specification also does not apply to devices (such as seismometers or open-loop piezoelectric accelerometers) that measure ac rather than low-pass and dc accelerations. Gravimeters are also not considered.
Figure la, Figure lb, and Figure 1c apply to pendulous proof-mass accelerometers. The forcer in Figure 1a is called a torquer. The figures must be appropriately modified for a translational proof- mass accelerometer. Torque-rebalance, capture-loop electronics and/or pickoff electronics are shown in Figure 1a. VBA oscillator electronics are shown in Figure lb and Figure lc. The acelerometer may employ a temperature sensor for thermal modeling, control, or monitoring. The dashed lines in Figure 1a, Figure 1b, and Figure 1c enclose the sensor part of the accelerometer, which responds to the acceleration input. The term“seismic system” is sometimes used in place of the term “acceleration sensor.” The electronics outside the dotted lines used to generate the accelerometer output and the temperature output, if needed, may be self-contained within or separate from the accelerometer package. The user- supplied electronics may include such items as power conditioner, capture electronics, output signal conditioner, temperature controller, reference clock, and test points. The sensor may employ stops to limit proof-mass displacement.
