Physical Logic Develops MEMS Accelerometers for Inertial Sensing and Navigation

Published: 15 Aug 2020 by

Physical Logic, an expert developer and manufacturer of MEMS accelerometers for inertial sensing and navigation, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Gold’ profile highlights how their low C-SWaP (cost, size, weight and power) open-loop and closed-loop sensors can be used for a wide range of various aerospace, land and maritime systems for defense and industrial applications, such as UAVs (unmanned aerial vehicles) UGVs (unmanned ground vehicles) and other robotic platforms.

The MAXL-CL-3000 is a family of advanced high-performance MEMS closed loop accelerometers for tactical and inertial navigation applications, incorporating a unique MEMS device and custom ASIC and providing a digital acceleration output. With a low C-SWaP footprint in a hermetically-sealed LCC44 package, and current consumption of less than 50 mA, these high-grade sensors enable high volume production with excellent reliability and reduced cost. They are ideal for incorporation into IMUs and inertial sensing systems that can compete with other market-leading devices.

MAXL-CL-3030 MEMS AccelerometerThe MAXL-CL-3030 is the flagship product of the MAXL-CL-3000 family, featuring a ±30g sensing range and available in several tactical and inertial performance grades with superior performance and excellent measurement accuracy. The MAXL-CL-3030 sensors provide one-year bias repeatability of down to less than 0.5 mg, one year scale factor repeatability of down to less than 400 ppm, and VRE of down to less than 25 µg/ g2 rms.

The MAXL-OL-2000 is a family of advanced open loop MEMS accelerometers available in a variety of sensing ranges. These high-performance sensors are ideal for inertial navigation and vibration sensing applications requiring superior measurement accuracy. The SWaP-optimized MAXL-OL-2000 devices are lightweight, with a low-footprint and a current consumption of less than 13 mA, and are enclosed in a hermetically-sealed LCC20 ceramic package.

MAXL-OL-2002C MEMS AccelerometerThe MAXL-OL-2002 is a state-of-the-art open loop MEMS accelerometer from the MAXL-OL-2000 family featuring a ±2g sensing range. With a one year bias repeatability of 0.5 mg (1σ) and a one year scale factor repeatability of 600 ppm (1σ) , this sensor provides high stability and ultra-low noise.

The MAXL-OL-2002 incorporates a custom ASIC that produces a differential analogue voltage output proportional to acceleration, providing a system output voltage range of ± 1.5 V. A temperature–proportional voltage output is also available for other system requirements.

Physical Logic also provides a family of export control-free open loop MEMS accelerometers, designed to provide high stability and low noise measurement. ±2g, ±5g and ±10g sensing ranges are currently available, with ±15g and ±20g to be added in the near future.
