Design of the Model 2422H series incorporates Silicon Designs’ own MEMS accelerometer chip, for an enhanced bias and scale factor over temperature performance specification and 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 variable capacitive accelerometers and chips are 100% designed, manufactured, and tested at the company’s facility in Kirkland, Washington, USA. This includes the manufacture of the chips and dies themselves.
