USB 3-axis Self Recording Impact Accelerometer X250-2

image of X250-2 impact sensor

General

The new and improved X250-2 self-recording three axis impact accelerometer is capable of recording +/-250g range or +/-28g range. This device is best suited for applications involving events that exceed 6g's, which are beyond the capabilities of the X6-1A or X6-2 products. The small compact device captures impact events with precise timing and records the data to the internal flash memory. The plain text comma separated data files are easily accessible via the USB mass storage device interface. The X250-2 operates approximately 3 hours using an internal, hardwired, rechargable lithium-polymer battery. Read more about our data logger product-line features.

Features

The X250-2 incorporates a 14-bit resolution analog-to-digital converter and a set of analog accelerometer sensors, each with a full scale range of 625g's. The X250-2 provides 26 counts per g in the low gain mode, which provides sufficient resolution to capture the acceleration and impact of an arrow. For moderate g-force scenarios, the X250-2 provides excellent sensitivity in the high gain mode. The table below summarizes the effective resolution at different g-forces and gain settings.
