Tactical Grade Quartz Flexible Accelerometer

The AC-4 series is suitable for high-temperature, high-vibration environments, such as oil well drilling and testing, bridge/dam tilt monitoring, coal mine safety testing, high-speed railway control, and ship attitude control.

A: MEMS accelerometers are cost-effective but less stable at high temperatures. Our quartz flexure design (AC-4) offers superior long-term stability, higher vibration resistance, and broader temperature ranges. Ideal for industrial applications like bridge monitoring or deep-sea drilling where MEMS would fail.

A: Temperature changes cause drift in scale factor and bias. Our design includes a built-in temperature sensor for compensation, with sensitivity <50 g/C (AC-4A). This ensures accuracy in extreme conditions, such as coal mines where temperature fluctuations are common.

A: Yes. It withstands 25g vibrations (20-2000 Hz) and 1000g shocks, as validated in our test procedures for bridge and dam monitoring. For example, in ship stabilization systems, it reliably measures acceleration during rough seas without calibration drift.

A: Factory calibration includes multi-point testing for bias, scale factor, and temperature coefficients. Systems are tested across 8 temperature points to ensure ppm-level repeatability. This ensures seamless integration into client systems without additional calibration.
