Silicon Designs (SDI) 1521-002 Acceleration Sensor

The Model 1521 is a low-cost integrated accelerometer for zero to medium frequency instrumentation applications requiring extremely low noise. The 1521 is designed to support harsh downhole drilling conditions,and the 2g version is ideal for seismic applications. Each tiny,hermetically sealed package combines a micromachined capacitive sensing element with a custom integrated circuit that includes a amplifier and differential output stage. It is relatively insensitive to temperature changes and gradients. Each device is marked with a serial number on the underside for easy traceability. An optional calibration test sheet (1521-TST) is also provided which lists the measured bias,scale factor,linearity,operating current and frequency response,• Seismic Monitoring • Downhole • Seismic Detection • Robotics • Safety Systems • Crash testing • Machine control • Vibration monitoring • Modal analysis • Vibration analysis • Instrumentation • Vehicle dynamics
