201 Series Accelerometer

201 Series Accelerometer

Description: The Model 201 is a low noise 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 ±100g. Featuring gas damped MEMS sensing elements, the model 201 provides a flat frequency response over an operating temperature range of -40°C to 125°C.

Features:

•  Low Noise

•  2 Pole Electronic Filtering

•  High Over-Range Protection

•  Low Current Consumption

•  Temperature Compensation
