Hermetic MEMS accelerometers operate from +5VDC
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. Modules are packaged in a rugged, IP67 rated, hermetically sealed lightweight titanium case, for added protection from moisture, dust, corrosion, and other contaminants. The device 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.
