SiliconDesigns- Tactical Grade MEMS Inertial Sensor
High-Accuracy Grade MEMS Capacitive Accelerometers
Silicon Designs, Inc. builds world-renowned, rugged, Variable Capacitance (VC) accelerometers with integrated amplification and an extremely rugged design for zero to medium frequency applications. SDI’s accelerometers offer full-scale sensitivity from 2g to 400g as standard range, most accelerometers can continue in spec operation after exposure of up to 5,000 g and limited temperature exposure to 175°C.
As the OEM of the MEMS accelerometers, SDI is able to provide exclusive benefits to customers otherwise absent in the industry. All of SDI’s accelerometers are built in-house, in the USA, which results in superb quality and the fastest lead times, plus the capabilities for qualification, custom specifications, and private-label solutions.
Over 30 years of experience makes SDI a MEMS accelerometer expert. SDI’s miniature capacitive accelerometer technology has received critical acclaim for innovation and versatility, proven by receiving the Tibbetts Award and induction into NASA’s Space Technology Hall of Fame. SDI uses military standards for production, guaranteeing a level of quality seldom found in similar accelerometers.
1525 - Inertial Navigation Accelerometer
The Model 1525 is the best in class, low-cost, integrated accelerometer for use in inertial and zero to medium frequency instrumentation applications requiring high repeatability and low noise. The 1525 was designed for maximum stability required by inertial applications.
