203 Series Accelerometer

203 Series Accelerometer

Description: The Model 203 is a low noise triaxial accelerometer offering both static and dynamic response. The accelerometer is packaged in an anodized aluminum housing with an integral cable. It is offered in ranges from ±2g to ±50g. Featuring gas damped MEMS sensing elements, the model 203 provides a flat frequency response over an operating temperature range of -40°C to 125°C. It was specifically designed for reliable performance in competitive Motorsport Racing.

Features:• Low Noise

• Low Current Consumption

• Ranges: ±2g to ±50g

• High Over-Range Protection

• Temperature Compensation

• 2 Pole Electronic Filtering
