MS3012 accelerometer widely used in high-speed train

As one of the new four great inventions, Chinese high-speed railway provides high speed, stable, comfort services for the passengers. has formed a high-speed railway technology platform and technology system with independent intellectual property rights.

SkyMEMS Accelerometers are based on silicon MEMS capacitive sensors, which offer higher performances in terms of size, power, reliability, long-term stability, signal to noise and robustness.

SkyMEMS Accelerometers have been widely used in the high-speed train, they are used to monitor several types of mechanical motions such as inertial force (acceleration), tilt (inclination), vibration and shock.

MS3012 accelerometer widely used in Seismic monitoring

Earthquake early warning systems use earthquake science and the technology of monitoring systems to alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. The seconds to minutes of advance warning can allow people and systems to take actions to protect life and property from destructive shaking.

Accelerometers are usually used where precision records of smaller seismic events are required. SkyMEMS accelerometers provides low noise and low frequency accelerometers, it can accurately measure the vibration changes, which are widely used in the seismic monitoring systems.

MS3012 accelerometer widely used in structural inspection

The development of safety systems and continuous monitoring of buildings, bridges, railways is very important to achieve these purposes. MEMS accelerometer sensors are used in structural inspection. If the high building vibration signal is abnormal, the monitoring system can get the signal and send out alarm.

FAQ

Q: What does the MEMS accelerometer measure?

A: An accelerometer is an electromechanical device that measures acceleration forces. These forces may be static, like the constant force of gravity pulling at our feet, or they could be dynamic – caused by moving or vibrating the accelerometer. They developed MEMS (micro electromechanical systems) accelerometers.

Q: What is MEMS accelerometer?

A: MEMS stands for micro electro mechanical system and applies to any sensor manufactured using microelectronic fabrication techniques. These techniques create mechanical sensing structures of microscopic size, typically on silicon. When coupled with microelectronic circuits, MEMS sensors can be used to measure physical parameters such as acceleration. There are two types of MEMS accelerometers: variable capacitive and piezoresistive. Variable capacitive (VC) MEMS accelerometers are lower range, high sensitivity devices used for structural monitoring and constant acceleration measurements. Piezoresistive (PR) MEMS accelerometers are higher range, low sensitivity devices used in shock and blast applications.

Q: How about the delivery time?

A: for our standard model, if we have them in stock, only need 2~3days to re-test before shipping, if it is out of stock, then need around 2 weeks to arrange the production and tests. For the ODM electronic product, if needing to modify the structure, it will need around 3~4 weeks to arrange the production and tests.

Q: How to arrange the payment?

A: about the payment, please pay to our company account, the beneficiary’s name: NANJING SKY MEMS TECHNOLOGY CO., LTD.  And our email is only @skymems.com to contact with u formally. To notice this to avoid the loss.
