Different fields have varying requirements for accelerometer parameters. For example, In aerospace applications, accelerometers are crucial for navigation and control systems. They must exhibit minimal bias drift and high resolution to ensure accurate positioning and orientation of aircraft and spacecraft. The accelerometers must handle a wide dynamic range of accelerations due to rapid changes in speed and direction during flight maneuvers. This makes ER-QA-03C for aerospace stand out, which has a wide range of ±60g, bias repeatability of less than 15 μg.
What's more, for marine applications, accelerometers must be resistant to harsh environments, including high humidity and saltwater exposure. Stability over long durations is critical for accurate navigation over extended periods, as INS are often used in submarines and ships.
In the oil and drilling fields, quartz accelerometers are required to meet specific criteria to ensure they perform effectively under harsh conditions. Here are the primary requirements for quartz accelerometers in these applications:
- High Temperature Tolerance:Must withstand extremely high temperatures typically found in downhole environments, often exceeding 150°C (302°F) and sometimes reaching up to 200°C (392°F) or higher.
- High Shock and Vibration Resistance:Should endure significant mechanical shocks and vibrations without compromising accuracy, as the drilling environment is highly dynamic and aggressive.
- High Sensitivity and Precision:Require high sensitivity and precision to detect subtle changes in movement and orientation, crucial for accurate directional drilling and monitoring.
On top of that, these requirements are also needed: Pressure Resistance, Robust Housing, Low Drift and Noise, Wide Frequency Response. So we recommend the ER-QA-03D for oil and gas, whose operating temperature is -55~180 ℃, with an input range of ±30g, bias repeatability <50μg, and scale factor repeatability <80 ppm.
