A small weatherproof Pendant Data Logger for measuring G forces, tilt, orientation, activity and motion.
The
HOBO Pendant G Acceleration Data Logger is a waterproof, three (3) channel
logger with 8-bit resolution that can record up to approximately 21,800 combined
x-, y-, and z-axis acceleration readings or internal logger events. The pendant
logger uses a coupler and optical base station with USB interface for launching
and data readout by a computer.
The
pendant G data logger can be used for a wide variety of experiments, demonstrations
and field studies by measuring dynamic acceleration resulting from motion,
shock or vibration. It can also detect static acceleration of gravity, making
it possible to measure tilt, inclination, and position.
The logger uses an internal three-axis accelerometer with a range of ±3G based on micro-machined silicon sensors consisting of beams that deflect with acceleration. These beams are arranged to act as a variable capacitor. As the beams flex, the capacitance changes proportionately. This capacitance change is converted to voltage, filtered and measured by the logger, and displayed in the software in units of g-force.
