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?

  • For the purpose of closing this discussion, I wanted to mention that Chandra and I had a great conversation about his research on high-temperature operation for the ADIS16255 (see ADIS16265 for the new version). We concluded this conversation with the message that, determining the root cause, with a high degree of probability, would likely be a time-consuming, costly exercise. Since the temperature was much higher than the rating of the device and this is outside of our current market focus, we are not able to support this investigation.  However, I wanted to mention that we are always interested in learning more about high-temperature applications.  For anyone that has application-specific questions like this, for an industry-driven program, we would be happy to discuss this with you in a private conversation, which the Engineer Zone supports. We look forward to hearing from you.  Special thanks to Chandra for his investment in studying the ADIS16255!
