(Silicon Designs Inc.: Kirkland, WA) -- Silicon Designs Inc., announces the immediate availability of stock quantities of its industry best-selling single axis Model 2210 series. These low-noise, low-cost MEMS capacitive accelerometer modules offer accurate and repeatable measurements across a variety of lower-frequency vibration testing applications, including those common to vibration analysis, machinery control, modal analysis, robotics, and crash event detection.

Offered in standard ranges from ±2 g to ±400 g, the rugged design of the Model 2210 series incorporates a MEMS capacitive accelerometer chip together with high-drive, low-impedance buffering. When used along with a Silicon Designs recommended mounting block accessory, such as the company’s own Model 2330-BLK, the series can reliably and flexibly measure vibration and acceleration on either one, two, or three orthogonal axes with equal accuracy and repeatability. The measurement versatility afforded by the Model 2210 series allows customers to specify just one part number for multiple, unique measurement requirements, thereby reducing in-house costs and inventory counts.

All Silicon Designs Model 2210 series MEMS capacitive accelerometer modules generate two analog voltage outputs which vary in response to applied acceleration. Customers can utilize either a single-ended or differential output, the latter of which doubles accelerometer sensitivity. The sensitive axis of the Model 2210 series 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, it is ±4 VDC. A simple-yet-robust four-wire connection and internal voltage regulator minimize supply voltage variation effects. The high-quality MEMS capacitive sense element of each Model 2210 series accelerometer module is packaged within a single, compact, lightweight, epoxy sealed and anodized aluminum housing occupying a total dimensional footprint of just 1 square inch.

All Model 2210 series MEMS capacitive accelerometer modules are relatively insensitive to temperature changes and offer quick, easy, self-calibration. Each product is 100-percent designed, developed, and manufactured at the company’s own global corporate headquarters and ISO9001-certified R&D center, located just outside of Seattle, Washington. Each accelerometer also undergoes rigorous quality testing prior to shipment. For detailed specifications, pricing, or additional information visit www.SiliconDesigns.com.

About Silicon Designs Inc.

Silicon Designs was founded in 1983 with the goal of improving the accepted design standard for traditional MEMS capacitive accelerometers. At that time, industrial-grade accelerometers were bulky, fragile, and costly. The engineering team at Silicon Designs listened to the needs of customers who required more compact, sensitive, rugged, and reasonably priced accelerometer modules and chips, which also offered higher performance. Resultant product lines were designed and built to surpass customer expectations. The company has grown steadily over the years, while its core competency remains accelerometers, with the core business philosophies of “make it better, stronger, smaller and less expensive” and “let the customer drive R&D” maintained to this day. Silicon Designs is also a 100-percent veteran-owned small business.
