High performance inertial MEMS sensors

High stability, high repeatability, digital, SMD MEMS acceleration sensors & angular rate sensors

Tronics is today the only provider of high performance inertial MEMS sensors to offer both closed-loop acceleration sensors and angular rate sensors with digital interface and SMD package.

Closed-loop digital MEMS inertial SMD sensors

Through our closed-loop, digital and SMD sensor architecture we have taken MEMS inertial sensors components to an unrivalled level of performance, stability, reliability and ease of integration.

Our closed-loop electronics, also called force-rebalance or force-feedback, brings several key advantages to our high performance MEMS inertial sensors, including :

superior linearity

exceptional behavior under vibrations and shocks

Our digital electronics is fully hard-coded and contains no software. This eases the certification of our sensors by our customers for safety-critical applications.

No compromise on stability and repeatability
We have taken care of every details to provide our acceleration sensors and our angular rate sensors with the highest possible level of stability and repeatability under vibrations and fast temperature changes. Thanks to those efforts, our sensors exhibit performances that were yet only achieved by bulky, expensive and non SMT solutions such as tactical-grade quartz sensors, Dynamically Tuned Gyros (DTG) and fiber optic gyroscopes.

For demanding high performance inertial systems

Our digital MEMS accelerometers and gyros are therefore well suited for system manufacturers requiring inertial sensors with high precision and high bias and scale factor stability and repeatability under strong vibrations and temperature changes. In addition, our digital SPI interface and our hermetic SMD package simplifies the system integration and reduces the bill of material and assembly costs for our customers compared to tactical-grade analog solutions.

We therefore enable them to quickly develop and produce small, light and affordable high performance systems such as:

  • Motion control systems,
  • IMUs,
  • INS
  • AHRS.

They are used for precision GNSS-assisted positioning and navigation, attitude and motion tracking and control, as well as optical stabilization in railway, land, marine and aerospace applications.

Free from export-control

Our standard MEMS inertial sensors are factory-calibrated and non-classified under dual-use export control despite their high level of performance. We manufacture those ITAR-free products in our own wafer fab, assembly and calibration line, located in France, close to Grenoble. We conduct product development and production according to IATF16949 quality procedures thus ensuring the highest level of care, quality and reliability for our customers.
