Physical Logic was founded in 2004, as a privately held Swiss company, headquartered in Zug, Switzerland, with a R&D and manufacturing center in Israel. Physical Logic develops and manufactures tactical and navigation grade MEMS (Micro Electro Mechanical Systems) based accelerometers. Our accelerometers have a wide range of high-end applications: vibration sensing, tilt sensing, seismic sensing and inertial navigation. The company maintains cost efficient supply chain capabilities, which include in-house design, assembly, testing and qualification. Physical logic has a variety of products. The first established family of products includes advanced open-loop MEMS accelerometers that offer extremely high linearity, ultra-low noise, excellent long term stability and significantly improved performances over the currently available tactical-grade MEMS accelerometers. With our flagship closed loop MEMS accelerometer product line, we managed to bridge the performance-cost gap of the high performance mechanical solutions. Our closed loop series MEMS accelerometers provide improved performance, such as scale factor linearity, bias stability and vibration rectification.
