The Model 2220 series is available in seven unique models, with standard measurement ranges from ±2 g to ±200 g, each with a wide frequency response measuring down to zero hertz. Each accelerometer module is housed within an epoxy-sealed rugged anodized aluminum housing, with mounting via two M3 screws. Its lower mass (10 g) and compact size (1" x 1" x 0.3") can help to minimize mass loading effects, making it ideal for zero-to-medium frequency acceleration and vibration measurements within a variety of industrial and commercial applications. The Silicon Designs Model 2220 series can respond to both DC and AC acceleration, either with two analog ±4V (differential); or 0.5 to 4.5V (single-ended) outputs that vary with acceleration. At zero acceleration, differential voltage output is nominally 0 VDC (DC response), with typical 1% cross-axis sensitivity. Onboard voltage regulation minimizes supply variation effects. Units are designed to withstand shock inputs of up to 2000 g over a standard temperature range of –55°C to +125°C. Each module is serialized for traceability and calibrated prior to factory shipment.
The combined low mass, small dimensional size, and low-impedance outputs of the Model 2220 make the series particularly ideal for flight test, aircraft flutter testing, vibration monitoring and analysis, robotics, biomechanics, automotive RLDA, machinery and equipment control, modal analysis, crash testing, and general in-laboratory applications. Non-standard g ranges, packages and connector configurations are available upon request.
