What's the Four Key Performance Indicators for a quartz accelerometer?

Quartz flexible accelerometers China Professional Quartz Accelerometers supplier-Hitech Sensors Tech Co., Ltd are high-precision, reliable sensors that excel in challenging environments like aerospace and defense due to their superior accuracy, low noise, and excellent temperature stability. They are capable of measuring minute acceleration levels, providing crucial data for applications such as inertial navigation, seismic monitoring, and oil drilling, where high performance and consistency are essential despite demanding conditions.  

Four Key Performance Indicators (KPIs) for a quartz accelerometer are Scale Factor Repeatability (consistency of the output for a given input over time), Zero Bias Repeatability (consistency of the zero output without input acceleration), Temperature Coefficient (the change in sensitivity or zero point with temperature), and Range (the maximum acceleration the sensor can measure). These indicators are crucial for evaluating the accuracy, stability, and reliability of quartz accelerometers in applications like inertial navigation systems.

Here are the four key performance indicators as following:

1. Scale Factor Repeatability:

This KPI measures how consistently the quartz accelerometer's output scales with input acceleration over time. A highly repeatable scale factor indicates a stable and predictable response from the sensor, which is vital for accurate navigation and positioning applications.

2. Zero Bias Repeatability:

Zero bias refers to the non-zero output of the quartz accelerometer when there is no actual acceleration applied. Zero bias repeatability quantifies the consistency of this output over time, reflecting the sensor's long-term stability and minimizing measurement errors caused by interference. 

3. Temperature Coefficient:

This indicator quantifies how much the quartz accelerometer's performance, specifically its scale factor and zero bias, changes with variations in temperature. A low temperature coefficient is crucial for applications in environments with wide temperature fluctuations, such as deep sea or space exploration. 

4. Range:

The range of a quartz accelerometer defines the maximum acceleration it can accurately measure. This is a critical parameter, as it directly influences the accelerometer's ability to handle the acceleration forces encountered in its intended application, such as vibrations, impacts, or high-speed maneuvers.
