Silicon Designs Low-Noise MEMS Accelerometer Series

Silicon Designs announced the global market introduction of its model 1521 surface mount accelerometer series.

According to the company, the durable design of the series incorporates its proprietary MEMS chip development and fabrication, which provides a MEMS variable capacitance accelerometer with up to 2,000 hours of measurement stability, in temperatures as high as +175 degrees Celsius, with 6,000 g shock survivability and zero signal degradation.

Designed as a pin-compatible drop-in replacement for the company’s model 1210 and 1221 series, the new model 1521 series features non-ferrous construction and a durable nitrogen-damped MEMS sensing element, housed within a miniature hermetically sealed gold ceramic 20-pin LCC or JLCC package. All Silicon Designs accelerometers feature a custom-integrated circuit with onboard sending amplifier and differential output stage, with a 0.5 to 4.5V single-ended or ±4V differential output, proportional to the amount of measured acceleration. Series units can respond to either DC or AC acceleration. Each accelerometer is fully calibrated and traceable.

The model 1521 series is available in standard measuring ranges from ±2 g to ±200 g, with nominal frequency response, either from 0 to 400 Hz ( ±2 g) or 0 to 3000 Hz ( ±200 g). The devices are also insensitive to temperature changes and gradients, with signal output unaffected by electromagnetic interference, and requiring no warm-up period.

Supported applications include oil and gas downhole monitoring; UAV inertial measurements; tilt and position measurements for antennas, solar panels, wind turbines, hydroelectric spillway doors, and elevators; civil structure seismic monitoring; industrial vibration monitoring and analysis; robotics; and machinery control.
