shock-resistant sensor

Discover how high-temperature accelerometers from Micro-Magic ensure accurate vibration and acceleration data in extreme conditions (-55°C to +180°C). Ideal for oil & gas, aerospace, automotive, and industrial applications. In industries such as oil and gas, aerospace, and automotive testing, equipment often needs to operate in extreme temperature conditions. How can we ensure that accurate vibration and acceleration data can still be obtained in these harsh environments? The high-temperature accelerometer is precisely the key technology designed to address this challenge. This article will take you through the working principles, core application scenarios, and innovative solutions of Micro-Magic in this field by introducing these "industrial temperature warriors". What is a high-temperature accelerometer? A high-temperature accelerometer is a sensor specifically designed for extreme environments, capable of maintaining stable operation within a temperature range of -55°C to +180°C (such as the AC-4 model by Micro-Magic). Compared to traditional accelerometers, it adopts special materials and structural designs to ensure that it can still provide accurate measurement data under high temperatures, high vibrations, and strong impacts. Take Micro-Magic's quartz accelerometer as an example. It uses a non-crystalline quartz mass block structure, responding to changes in acceleration through bending motion. This design brings three major advantages: Bias stability: <10mg (AC-4 model) Temperature sensitivity: <100ppm Axis alignment stability: Ensuring long-term measurement consistency The four core application scenarios of high-temperature accelerometers 1. Oil and gas industry: "Underground navigator" for drilling operations In the MWD (Measurement While Drilling) system, high-temperature accelerometers play an irreplaceable role. Taking the AC-6 (a dedicated model for MWD) as an example, it can withstand underground high temperatures (up to 150°C) and 1000g of impact, providing three key supports for drilling operations: Real-time positioning: Accurately measure the position and inclination of the drill bit, improving drilling accuracy Safety warning: Detect abnormal vibrations to prevent downhole accidents Efficiency optimization: Reduce non-productive time through continuous monitoring, according to industry reports, it can reduce operation costs by 15-20% 2. Aerospace: The "Silent Guardian" of Flight Safety The aircraft engines and fuselage structures endure extreme conditions during flight. The high-temperature accelerometer from Micro-Magic (such as the AC-3 shock-resistant model) provides triple guarantees for the aerospace industry: Structural health monitoring: Real-time measurement of vibration in key components to prevent fatigue damage Engine diagnosis: Detection of abnormal vibration patterns to identify potential faults in advance Flight testing: Provision of precise dynamic performance data during the development of new aircraft models 3. Vehicle Testing: "Performance Judges" under Extreme Conditions From crash tests to high-performance validations, the high-temperature accelerometer provides objective quantitative data for the automotive industry: Crash Safety: Measuring instantaneous impact forces (up to ±30g range), evaluating the effectiveness of safety systems Durability Test: Long-term monitoring of component vibration characteristics in high-temperature environments Performance Validation: Ensuring the reliability of sports cars and racing cars under extreme driving conditions 4. Industrial Applications: Key Sensors for Intelligent Manufacturing In fields such as power plants, heavy industry, and special robots, high-temperature accelerometers also prove their worth: Turbine monitoring: A key data source for preventive maintenance Heavy machinery: Vibration monitoring can extend equipment lifespan by over 30% Industrial robots: Especially in high-temperature working units such as welding and casting Micro-Magic's Innovative Solutions: Designed for Extreme Environments As a leading supplier of inertial systems in the industry, Micro-Magic's high-temperature accelerometer series boasts several unique advantages: 1. Flexible Configuration: Analog output for easy system integration Multiple installation options for square/round flanges On-site adjustable range (e.g., ±10g to ±30g) 2. Intelligent Temperature Compensation: Built-in temperature sensor for automatic thermal compensation, ensuring measurement accuracy across the entire temperature range 3. Thermal Protection Design: Some models are equipped with an external amplifier, effectively isolating the impact of high temperatures on sensitive components 4. Recommended Models: AC-4: The top choice in the oil and gas industry, with a working temperature range of -55 to 180°C, and a bias repeatability of <50μg AC-6: Specifically designed for MWD, with shock resistance of 1000g, suitable for deep well measurements AC-3: Anti-vibration type, suitable for aerospace high-frequency vibration environments Cutting-edge Technology and Future Outlook As industrial equipment operating conditions become increasingly demanding, high-temperature accelerometer technology is also continuously evolving. The new generation of products being developed by Micro-Magic will feature: A wider working temperature range (-65 to 200°C) Higher vibration tolerance (2000g shock) Digital output and wireless transmission capabilities Conclusion High-temperature accelerometers are indispensable "sensory extensions" in modern industry. They continuously provide reliable measurement data in extreme environments that are beyond human vision and reach.
