Accelerometers Enhanced For Higher Temps

(Silicon Designs)

Silicon Designs has enhanced performance of its compact, low-mass single axis Model 2220 series MEMS VC accelerometers. Design of the enhanced Model 2220 series features proprietary high-performance MEMS chips, along with high-drive, low-impedance buffering, for improved bias and scale factor over temperature performance. These specifications are touted as being unmatched among other industry MEMS VC accelerometer manufacturers yet are still offered by Silicon Designs at a highly competitive price point.


The Model 2220 series is available in seven models, with standard measurement ranges from ±2g to ±200g, each with a wide frequency response measuring down to 0 Hz. Each accelerometer module is housed within an epoxy-sealed rugged anodized aluminum housing, with mounting via two M3 screws. Its mass 10g and size of 1 in. x 1 in. x 0.3 in. can help to minimize mass loading effects, making it viable for zero-to-medium frequency acceleration and vibration measurements within a variety of industrial and commercial applications.


The components 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 up to 2000g over a standard temperature range of –55°C to +125°C. Each module is serialized for traceability and calibrated prior to factory shipment.
