TDK expands its high-temperature MEMS accelerometer portfolio for energy market applications

TDK Corporation announces the expansion of its high-performance MEMS inertial sensor portfolio with the Tronics AXO315^®T1, a high-temperature MEMS accelerometer offering a ±14 g input range and a digital interface for measurement while drilling (MWD) applications operating up to +175 °C.

With this launch, TDK advances its temperature robustness roadmap following the introduction of the Tronics AXO315T0 in June 2025, its first digital MEMS accelerometer qualified for oil and gas applications up to +150 °C. This further strengthens TDK’s position in high-reliability MEMS inertial sensors for precise downhole navigation in extreme environments.

The AXO315T1 is based on TDK’s proprietary closed-loop architecture, already proven across several Tronics sensors. This design delivers a tenfold improvement in vibration rectification error compared with conventional open-loop MEMS accelerometers. The device provides a cost-effective, digital, low-SWaP (Size, Weight, and Power) alternative to quartz accelerometers for inclination measurement in directional drilling tools exposed to severe temperature and vibration conditions.

With a powered lifetime exceeding 1000 hours at +175 °C, the AXO315T1 supports the development of next-generation MWD tools addressing the accuracy and productivity requirements of complex and unconventional drilling operations.

AXO315T1 sensors and evaluation boards are available for sampling and customer evaluation.
