Physical Logic develops and manufactures advanced MEMS (“Micro-Electro-Mechanical System”) accelerometers for a wide range of high-end applications. Rugged, low C-SWaP (cost, size, weight and power) open and closed loop sensors are suited to a broad spectrum of defense applications including aerial and maritime systems as well as land-based vehicles and equipment.
Based on fully differential capacitive sensing architecture to enable noise and parasitic rejection, Physical Logic develops Open-Loop and Closed-Loop MEMS accelerometers for tactical and inertial navigation applications such as finding north, target location, tilt sensing and antenna alignment.
Manufactured at our state-of-the-art in-house production facility, all our manufacturing processes are fully AS9100D and ISO9001-2015 compliant and utilize our fully-qualified, high-capacity assembly and test lines.
Advanced Low-noise MEMS Sensor TechnologyCompact & hermetically-sealed tactical grade MEMS units
Based on micro-machined silicon MEMS devices, Physical Logic advanced accelerometers are combined with a custom low-power ASIC (application-specific integrated circuit).
Featuring a unique in-plane geometry they enable:
• High reliability
• Extremely low thermo-mechanical noise levels
• Excellent linearity
Physical Logic low-noise MEMS sensors offer clear performance advantages over other inertial and tactical grade MEMS units. Hermetically-sealed at atmospheric pressure our rugged MEMS and ASIC chips feature excellent long-term stability and are integrated into a highly-compact ceramic package.
