The model 2445 series from Silicon Designs is a family of single-ended, low-noise analog micro-electro-mechanical systems (MEMS) capacitive accelerometer modules, designed to support low-to-medium frequency triaxial measurement requirements. The rugged design features three orthogonally mounted low-noise MEMS sensing elements, packaged in a nitrogen-damped, epoxy-sealed aluminum housing with a ±5-V single-ended output referenced to external ground. Units are available with individual standard measurement ranges from ±2 to ±400 g and operate over a temperature range of -55 to +125°C (-67 to +257°F). Model 2445 features a six-wire connection with an instrumentation amplifier on each axis for higher drive capability and low-impedance output. Onboard voltage regulation and an internal voltage reference reduce power consumption. Units respond to both dc and ac acceleration, and custom measurement and temperature ranges are available.
