Silicon Designs, Inc. 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 capacitive 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 capacitive 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 capacitive 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.
