New Low Voltage +5 VDC Specialty Hermetic MEMS Capacitive Accelerometer Modules
Kirkland, Washington, USA - Silicon Designs, Inc. (www.silicondesigns.com)(SDI), a 100% veteran owned, ISO9001:2015 certified, and U.S. based global industry leader in the design, development and manufacture of highly rugged industrial-grade MEMS capacitive accelerometer chips, modules and supporting data acquisition, today announced the global market introduction of its Model 2422H low-voltage, specialty hermetic, MEMS capacitive accelerometer modules.
Available in eight unique models, with standard ranges from ±2 g to ±400 g, the Model 2422H series is expressly designed for zero-to-medium frequency vibration and acceleration sensing, in commercial and industrial applications where a hermetically sealed case and +5 VDC regulated power supply are absolute requirements. Design of the Model 2422H series incorporates Silicon Designs’ own MEMS capacitive accelerometer chip, for an enhanced bias and scale factor over temperature performance specification that is unmatched in the industry, along with excellent long-term stability. Modules are packaged in a rugged, IP67 rated, hermetically sealed lightweight titanium case, for added protection from moisture, dust, corrosion, and other contaminants. Units are easily mounted via two screws, adhesive, or a magnet. The IP61 rated connector of the Model 2422H meets IP67 requirements when sealed with a boot, sleeve, or heat shrink.
The Model 2422H series produces differential analog output voltage pairs (AON & AOP) which vary with acceleration. Signal outputs are fully differential about a common mode voltage of approximately 2.5V. Modules can support either a ±4V differential or 0.5V to 4.5V single ended output, for complete measurement flexibility. They can also respond to both DC and AC (0 to 2000+ Hz) acceleration. At zero acceleration, differential voltage output is nominally 0 VDC; at ± full-scale acceleration, it is ±4 VDC. Units are also relatively insensitive to temperature changes and gradients over a standard operating temperature range of -55°C to +125°C. Each accelerometer module is shipped directly from the factory fully calibrated and serialized for traceability.
All of Silicon Designs MEMS capacitive accelerometers and chips are 100% designed, manufactured, and tested at the company’s state-of-the-art facility in Kirkland, Washington, USA. This includes the manufacture of the chips and dies themselves. The completely vertically integrated manufacturing processes of Silicon Designs allow the company to offer high-quality products at still-highly competitive pricing, along with some of the industry’s shortest lead times. Standard model quantities can typically ship in less than two weeks.
About Silicon Designs, Inc. Silicon Designs (www.silicondesigns.com) was founded in 1983, with the goal of improving the accepted design standard for MEMS capacitive accelerometers. At that time, industrial-grade accelerometers on the market were bulky, highly 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 that also offered higher performance. Resultant product lines were designed and built to surpass customer expectations. The company has grown steadily over the years, though its core competency remains accelerometers, with the business philosophy of “Make it better, stronger, smaller and less expensive” maintained to this day.
