Q: Why does IMU80 IMU module become so hot selling product?
A: 1) IMU80 IMU module has been widely used in unmanned vehicles, smart agriculture, AGV, etc., and now the sold qty can reach 50k per year 2) since we produce IMU80 in big qty, so IMU80 IMU module can enjoy ultra-cost-effective, which assure that it can be widely used. 3) IMU80 is similar as ADIS16460 with better performance, and we can provide faster delivery, usually we have them in stock, we only need to do the tests before delivery. 4) we can provide customized design based on this model, so that make the IMU module more suitable for your application, we can provide the most flexible solution to our customers. 5) IMU80 IMU module provide the most reliability, its quality has been proven by the leading companies in China.
Q: What is IMU80’s g-sensitivity parameter?
A: it is 0.1dps/g
Q: What is shocking resistance of IMU80?
A: it is 2000g, <1ms, with power or power off.
Q: How to keep IMU80 bias calibration good after time? What a procedure?
A: In fact, before we do the high and low temperature compensation and turntable calibration, we have done ESS in the high and low temperature box for 48 hours to release the environmental stress and ensure that the stress deformation is as small as possible. But after a long time, 10 months or a year later, due to the characteristics of the MEMS sensor itself, the performance may have little change. At this time, if the customer has high accuracy requirement, they can return to our factory for calibration again.
Q: if turning off the fusion algorithm that IMU80 itself has, can be the output frequency of IMU80 up to 500Hz?
A: we have done 400Hz before, for 500Hz, theoretically IMU80 can.
Q: What is IMU80 working temperature?
A: The test temperature is -40 to 85 °, and the actual temperature may exceed 85 ° when testing high temperature. Actually, during the test, we kept IMU80 stay at both -40° and 85° for an hour
Q: What is IMU80’s sampling frequency of raw inertial measurements?
A: 1Khz Q: Whether IMU80 support raw 1k frequency data output?
A: no, IMU80 doesn’t support direct 1k frequency raw data output, IMU80 needs to do the data processing for the raw data.
Q: How about IMU80’s bandpass filter?
A: IMU80 has 3rd order low pass filter inside, and the cutoff frequency can be set by the IMU80 management software. And the low pass cutoff frequency should be set according to the actual application. And the low pass filter is mainly used to filter some high-frequency noise interference. Customers need to test the interfering signal frequencies in their own environment and then set the cutoff frequency. If the settings are wrong, the data will be worse. For example, if the IMU80 is used in the vehicle, we suggest that set the cutoff frequency into 25Hz for accelerometer, 30Hz for gyro, and test it at your side. And to get better performance, please contact with us and let us know your application, so that we can recommend our solution for you. Usually first analyze the test data, and test the frequency spectrum, then set the parameter, and then test again to do the best settings.
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.
