Elevated Temp. effect on ADIS16255.

Hello,

I used ADIS16255 single axis gyro in the application where temp. reached to 125 deg C and 150 Deg C. Since ADIS16255 is recommended to operate up to 85 Deg C, I saw significant increase in temperature dependent bias (around 3.2 deg/s) at 125 deg C and (around 5.2 deg/s) at 150 Deg C. This temperature dependent bias at 125 and 150 C calculated after noise filtering. Does anyone know the reason for increase in bias at such elevated temperature?

Does this gyro has any stopped functioning mechanism at elevated temperature? If so, at what specific temperature this gyro stopped or creased to function?

  • Dear NevadaMark,

    Thanks for sharing your thoughts. This information is really helpful as it explains non-linear bias at high temp. However, I have couple of questions on the strange behavior of gyro I observed at high temp. Since It is difficult to describe this phenomenon by word, I would appreciate if you can send me your email address and I would be happy to discuss these results.

    Regards,
