Tronics ran extensive qualifcation campaigns on several MEMS accelerometers with this new ultra-low noise gyro- scope into a single system will result in a 100% MEMS-based hundreds of devices to make sure their performance re- mains stable in severe conditions. This includes aggressive MWD module, able to eliminate feld failures, decrease main- tenance and calibration costs, and guarantee frst-time drill- thermal cycling, wide-spectrum vibration tests with ampli- tude of up to 20 g rms at high temperature, start-up tests ing success even for the most complex borehole trajectories.

After decades of enabling land, air and sea applications in cold and hot conditions to ensure the sensors can be triggered at any time, as well as accelerated aging at high with its MEMS products portfolio, Tronics Microsystems temperatures to guarantee an operating lifetime of more positions itself as a key provider of high-performance

The miniature ceramic package of AXO351T0 and tivity and reliability requirements of the energy market.

AXO315T1 perfectly fts into applications with con- strained form-factors, such as the ones encountered in downhole directional modules with small diameters (typi- cally less than 2 inches). The built-in 24-bit SPI interface removes the need for additional components at system level and helps decrease the bill of materials.

With AXO351T0 and AXO315T1, Tronics Microsys- tems offer a digital, cost-effective and low-SWaP alternative to high-temperature quartz accelerometers for directional drilling applications, with no compromise on performance.

Towards a 100% MEMS-based directional module

Tronics is currently ramping up a new MEMS gyroscope with an extremely high level of resolution, able to sense the rotation of the Earth and determine azimuth with an ac- curacy of less than 1 degree in only one minute.
