US Patent No: 9435819

Autonomous temperature accelerometer sensor

---

Abstract

---

A turbine environment wireless transmitter for monitoring bearing health inside jet turbines. This transmitter has the ability to operate in 225 to 300 degree Celsius environments and monitor real time bearing temperature and vibration and transmit that data to a centralized system for processing. The system is powered by a built in thermal electric generator, which produces power in response to a thermal gradient across it. The information transmitted is used to monitor and diagnose a bearing operating parameters in real-time and predict a failure event before any damage occurs.
