TDK Corporation announces the extension of its high-performance MEMS inertial sensors portfolio with Tronics AXO315®T1, a high-temperature MEMS accelerometer with ±14 g input range and a digital interface for measurement while drilling (MWD) applications operating up to +175 °C.
With this launch, TDK is taking the next step in temperature robustness, following the release of the Tronics AXO315T0 in June 2025 its first digital MEMS accelerometer to be qualified for oil and gas applications at temperatures of up to +150 °C. This confirms the company's position as a leading provider of high-reliability MEMS inertial sensors for precise downhole navigation in extreme environments.
The AXO315T1 is powered by TDK’s unique closed-loop architecture, which has already been proven on several Tronics sensors. This architecture enables a 10x improvement in vibration rectification error compared to traditional open-loop MEMS accelerometers. The device is a cost-effective, digital, and low-SWaP (Size, Weight, and Power) alternative to quartz accelerometers for inclination measurement in directional drilling tools operating in harsh temperature and vibration conditions.
With a lifetime of more than 1000 hours at +175 °C, it paves the way for a new generation of MWD tools to meet the accuracy and productivity requirements of complex and unconventional drilling operations.
AXO315T1 sensors and evaluation boards are available for sampling and customer evaluations.
