► Physical Logic Introduces Next Generation Inertial Grade Closed Loop MEMS Accelerometers – the MAXL-CL-3000 Family

August 29 2019, Physical Logic ‒ a leader in high-precision open and closed loop MEMS (Micro-Electro-Mechanical System) accelerometers for the security, defense, energy, industrial, and healthcare markets ‒ introduces its next generation inertial grade closed loop MEMS accelerometers, the MAXL-CL-3000 Family, at DSEI. The company’s groundbreaking advances deliver exceptional short-term and long-term performance, comparable to Navigation Grade electromechanical quartz accelerometers.

Physical Logic is the first company in the world to market a closed loop Micro-Electro-Mechanical System (MEMS) accelerometer that rivals very high precision electromechanical quartz accelerometers. These accelerometers provide highly accurate measurements at lower cost as well as reduced weight and size.

North finding and inertial navigation applications are enabled by a major improvement in warmup performance that achieves time-to-full-performance in less than 2 seconds, with typical bias drifts of < 30 µg during the first 5 hours of operation. In addition, a wide range of aerial missions can be integrated due to a reduction in noise specification limits to 30µg/√Hz.

According to Ms. Katja Beyer, the company’s CEO, “We are proud to be the first company to introduce to the navigation market to a closed loop MEMS accelerometer with bias-related parameters comparable to Tactical Grade, and scale factor-related parameters comparable to Navigation Grade electromechanical quartz accelerometers.

“We met and surpassed our major technological targets ‒ upgrading all MAXL-CL-3030 bias-related parameters (30g sensing range closed loop MEMS accelerometer) as well as developing 2 new products ‒ 15g (MAXL-CL-3015) and 50g (MAXL-CL-3050) sensing range accelerometers ‒ for the MAXL-CL-3000 family.” DSEI, September 13-16, London, Israel Pavilion, South Hall, Stand S5-220
