Physical Logic has introduced its next generation inertial grade closed loop MEMS accelerometers, the MAXL-CL-3000 Family, at DSEI. The company’s advances deliver exceptional short-term and long-term performance, comparable to Navigation Grade electromechanical quartz accelerometers. Physical Logic will be found in the Israel Pavilion, South Hall, Stand S5-220, at DSEI.

Physical Logic is the first company in the world to market a closed loop Micro-Electro-Mechanical System (MEMS) accelerometer that rivals 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 two seconds, with typical bias drifts of <30µg during the first five 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.

Katja Beyer, CEO, said: “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 two new products, 15g (MAXL-CL-3015) and 50g (MAXL-CL-3050) sensing range accelerometers, for the MAXL-CL-3000 family.”
