Quartz Accelerometers

A quartz accelerometer is a precision force-balance accelerometer whose proof mass is a quartz pendulum. The servo loop holds the pendulum at null and the restoring current is the acceleration measurement — a principle that delivers high stability, low noise, and excellent long-term repeatability for inertial-grade sensing.

Catalog quartz accelerometers cover compact to navigation-grade form factors with published input range, bias, scale factor, temperature coefficients, and long-term repeatability specifications. Quartz flexure technology is the standard choice where MEMS devices cannot meet bias-stability or repeatability requirements. Selection is driven by range, bias performance over temperature, output format, and mounting constraints.

Catalog quartz flexure accelerometers. Full bias, scale factor, thermal, and mechanical specifications are published per model.

Key Selection Parameters

Input Range

Full-scale acceleration, typically ±10 g to ±60 g. Size the range to the platform's maximum sustained plus transient acceleration.

Bias & Repeatability

Composite bias error and its one-month or one-year repeatability dominate navigation error. Compare only under stated conditions.

Scale Factor Stability

Scale factor error and its temperature coefficient determine accuracy at high g. Critical for long-range dead reckoning.

Temperature Coefficients

Bias and scale factor temperature sensitivity set uncompensated error over the operating range; check whether the model publishes modelled residuals.

Output & Interface

Analog current output into an external sampling resistor is typical — confirm the interface electronics and noise at the chosen resistor value.

Selection Workflow

  1. 01

    Size the range

    Select input range to cover worst-case sustained and transient acceleration without saturation.

  2. 02

    Budget the bias

    Allocate bias and repeatability error against the navigation or stabilization accuracy target.

  3. 03

    Check the thermal path

    Review bias and scale-factor temperature coefficients — and modelled residuals where published — against the operating profile.

  4. 04

    Inquire with the shortlist

    Send candidate models and operating conditions — configuration and availability are confirmed per project.

Typical Applications

  • Inertial navigation and guidance systems
  • Platform stabilization and pointing
  • Tilt and inclination measurement under motion
  • Precision vibration and motion monitoring

Testing Considerations

  • Compare bias figures only with their stated conditions — 1σ window, temperature range, and warm-up state all change the number.
  • Verify repeatability over the timescale relevant to the application (4-hour, 1-month, 1-year figures differ materially).
  • Confirm output noise at the actual sampling resistor used in the interface electronics.
