Silicon Designs, Inc. (www.silicondesigns.com), a leading designer and manufacturer of highly rugged commercial- and inertial-grade MEMS DC accelerometer chips, modules, and supporting data acquisition, today announced the global market availability of its Model 2422 Series.

The Model 2422 Series offers low-noise, low-voltage (5 VDC) and low-cost acceleration and vibration sensing within zero-to-medium frequency instrumentation applications. Series models are available in eight standard ranges, from ±2 g to ±400 g. They are further offered with choice of either a ±4V differential or 0.5V to 4.5V single ended output. Series modules can reliably measure and respond to both DC and AC acceleration (0 Hz to more than 3000 Hz). Their robust design seamlessly combines both a micro-machined capacitive sense element together with a custom integrated circuit. Series internals are packaged within a lightweight, epoxy sealed, and rugged anodized aluminum case, further terminating in a 3-foot integral shielded cable. Units are relatively insensitive to temperature changes and gradients over a range of -55°C to +125°C.

The low-noise internal MEMS DC sense element contained within the Model 2422 Series is 100% designed and manufactured in the USA at Silicon Designs global corporate headquarters and R&D center, located just outside of Seattle, Washington. As the OEM of its own MEMS DC sense elements, Silicon Designs is able to carefully regulate its own R&D and manufacturing processes, thereby ensuring that each Model 2422 Series module is manufactured to be virtually identical within any given g-range. It also allows Silicon Designs to offer a standard product range with both long-term stability and enhanced bias and scale factor over temperature performance specifications that are unmatched. All Silicon

Designs MEMS DC accelerometers are in-house tested, programmed, calibrated, and verified to ensure their utmost measurement accuracy and reliability. They are also fully serialized for traceability before shipment.

In addition to its Model 2422 Series, Silicon Designs offers a specialty hermetic model variation, the 2422H Series, also as standard product. The Model 2422H Series incorporates all of the same low-noise, high-performance internal components as its non-hermetic counterpart, with the additions of enhanced temperature compensation; a rugged, IP67 rated, hermetically sealed lightweight titanium housing; and IP61 rated connector. These added features afford the accelerometer module added protection from moisture, dust, corrosion, and contaminants, all of which can affect measurement integrity. Other standard and custom accelerometer design modifications are available upon request. Please consult the factory for details.

The Model 2422 Series is ideal for the support of a variety of in-laboratory zero-to-medium frequency instrumentation requirements in automotive, aerospace, industrial, power generation, and test and measurement, and particularly, where low-noise, a +5 VDC regulated power supply, and long-term stability are needed.

About Silicon Designs, Inc. Silicon Designs, a 100% veteran-owned small business, was founded in 1983 with the goal of improving the accepted design standard for traditional MEMS DC 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, though which also offered higher performance. Resulting product lines were designed and built to surpass customer expectations. The company has grown steadily over the years, while its core competency remains accelerometers. The Silicon Designs core business philosophies of “make it better, stronger, smaller and less expensive” and “let the customer drive R&D” are maintained to this day.
