MEMS Variable Capacitive Accelerometers
Page 1 of 1
A high-precision accelerometer uses a simple four-wire snap-in removable connector and is designed to allow users the added ability to exchange, move, reposition and replace accelerometers within a given test setup for greater flexibility, convenience and cost savings. The model 2266 from Silicon Designs is expressly tailored for zero-to-medium frequency applications and offers integral amplification and high drive, low impedance buffering for precision measurements.
The accelerometer produces two analog voltage outputs and supports both single-ended and differential modes. Signal outputs are fully differential about a 2.5V common mode voltage. Sensitivity is independent from the supply voltage of +8 to +32V. At zero acceleration, the output differential voltage is nominally 0 VDC; at full scale acceleration, the output differential voltage is ±4 VDC. The sensors feature onboard voltage regulation and an internal voltage reference, which eliminates precision power supply requirements.
The low impedance outputs of the Silicon Designs model 2266 will drive more than 100 meters of cable, with an overall flexibility that allows them to be used within a wider variety of applications.
