Typical Application

1. Inertial Navigation System (INS)
MAS3012 provides high-precision triaxial acceleration measurement, suitable for aerospace, ship navigation, AGV (automatic guided vehicle), and other systems that require extremely high accuracy of inertial data. When used in combination with gyroscopes and magnetometers, high-performance inertial navigation and attitude estimation can be achieved.

2. Platform stability and attitude control
It is used in systems such as optoelectronic pods, radar antennas, and drone-hoovering platforms to help achieve rapid attitude correction and dynamic stability through high-dynamic response capabilities, especially suitable for systems with motion interference and complex dynamics.

3. Oil drilling and underground monitoring
In the oil and gas industry, MWD (measurement while drilling) tools can be embedded for underground formation motion perception and drilling direction control. Its anti-seismic and anti-temperature capabilities enable it to work stably in high-pressure and high-temperature underground environments.

4. Civil engineering structural health monitoring
MAS3012 is widely used in vibration monitoring and structural response analysis of key infrastructure such as bridges, tunnels, dams, and wind power towers. It can realize 24-hour data collection and early warning monitoring and effectively support the deployment of SHM systems.

5. Industrial machinery status detection
Integrated in high-end CNC equipment, wind turbines, industrial robots, and other industrial equipment, it monitors small vibrations and acceleration changes to help companies perform predictive maintenance and fault diagnosis.

6. Military and aerospace measurement systems
In missiles, rockets, tactical aircraft, and other platforms, it is used as the core module of the inertial measurement unit (IMU). It has excellent anti-shock and anti-interference capabilities and is one of the key sensors for achieving precise guidance and attitude judgment of weapon systems.

Product Advantages

1. Closed-loop structure design, higher precision
MAS3012 triaxial MEMS capacitive accelerometer adopts a closed-loop structure MEMS sensor element, which has higher linearity, stability, and dynamic response performance than open-loop structure, and is especially suitable for navigation and control systems with strict requirements on measurement accuracy and consistency.

2. High dynamic range, adaptable to complex environments
The dynamic range of ≥110dB allows the product to provide clear data in scenes from low-speed movement to high-speed impact, ensuring accurate perception under variable movement conditions.

3. Ultra-low noise, suitable for micro-dynamic detection
The ultra-low noise characteristic of ≤1.0μg/√Hz makes it suitable for high-sensitivity detection tasks of micro-vibration and micro-offset, and is widely used in scientific experiments, micro-mechanical systems, and high-end detection equipment.

4. Excellent environmental reliability
After professional packaging design, MAS3012 can still operate stably for a long time in harsh environments such as high humidity, high temperature, severe vibration, electromagnetic interference, etc., ensuring the continuity of key tasks and data credibility.

5. Lightweight and small size, easy for system integration
The compact design is suitable for embedding in systems with limited volume, convenient for integration with existing control systems and data acquisition modules, and provides highly flexible layout options for equipment manufacturers.

6. Strong compatibility, support for customization of multiple output interfaces
A variety of signal interfaces (analog, voltage, current, SPI, I2C, etc.) can be provided according to customer needs, which is convenient for connection with various embedded systems or main control units to achieve plug-and-play.

FAQ

Q: How long is the delivery time of the products?
A: Usually we have stock for every type of products, if the product that you selected we have in stock, then we only need to re-test it before leaving the factory, so the delivery time is around 1~2 days; if we don’t have them in stock, then we need to arrange the production, the delivery time will be around 2 weeks. For the customer-oriented design products, our engineers will give the approximate delivery time according to the technical requirements.

Q: If needing to do the customer-oriented design product, what procedures will be followed?
A: If you want to do the customer-oriented design product, please contact with our pre-sale technical support engineer, or enter our ODM service in www.skymems.com, and write down the technical requirements online, our engineers will contact with u asap after we get your requirements. Then we will clarify the technical specs together, and confirm the customer requirements together, then start to do the sample developing.

Q: How about the payment conditions?
A: we accept 30% prepayment in advance, and the balance 70% payment before the delivery. For the customer-oriented design product, the payment will be discussed together.

Q: How long is the product warranty?
A: Usually, our product warranty is one year. If you want to have longer warranty period, please contact with your sales manager to buy longer warranty service. Our products enjoy very high quality, and its MTBF is more than 100000hours.

Q: How will we do if the product has the quality problem?
A: Our products have passed very strict tests before delivery, so it is very low probability to have quality problem.
