Silicon Designs has upgraded its Model 2210 series of accelerometer chips to include measurement capabilities on one, two, or three orthogonal axes.
Silicon Designs is veteran-owned small business and industry expert in the design, development and manufacture of highly rugged industrial-grade MEMS capacitive accelerometer chips and modules.
Accelerometers is an electromechanical device used to measure acceleration forces, while MEMS stands for micro-electro-mechanical systems.
Silicon Designs says its low-noise single axis Model 2210 accelerometer modules integrate a MEMS VC accelerometer chip with high-drive, low-impedance buffering for reliable, repeatable measurements.
When used with a Silicon Designs mounting block, such as the Model 2330-BLK, the Model 2210 can effectively measure on either one, two, or three axes, allowing for the specification of a single part number for multiple requirements, thereby reducing in-house inventory counts, says the company.
Offered in ranges from ±2 to ±400 g, the Silicon Designs Model 2210 Series generates two analog voltage outputs which vary in response to applied acceleration. Customers can utilize either single-ended or differential output, the latter of which doubles accelerometer sensitivity over single-ended versions, adds the company.
The sensitive axis of the Model 2210 is perpendicular to the package bottom, with positive acceleration defined as a force pushing on the bottom of that package. Output scale factor is independent from the supply voltage of +8 to +32V. At zero acceleration, differential output voltage is nominally 0 VDC; at full scale, ±4 VDC.
Silicon Designs says the sensing elements of the Model 2210 are packaged within a compact, lightweight, anodized epoxy sealed aluminum housing, occupying a total footprint of just one square inch.
Their design features a “simple-yet-robust” four-wire connection and internal voltage regulator, which minimizes supply voltage variation effects, claims Silicon Designs.
Units are relatively insensitive to temperature changes and feature quick, easy self-calibration. All Silicon Designs accelerometer modules and chips are 100 per cent designed, developed and manufactured at the company’s global corporate headquarters and MEMS fabrication facility near Seattle, Washington, USA.
Each unit undergoes rigorous quality testing prior to shipment, according to the company.
Silicon Designs says the Model 2210 MEMS VC accelerometer modules are “ideal” for lower frequency vibration testing requirements, including vibration analysis, machinery control, modal analysis, robotics and crash testing.
With their versatile design and performance reliability, they may be specified within a variety of aerospace, automotive, defense, energy, industrial, and test and measurement applications, adds the company.
