Accelerometer -25..25 g
The High g Accelerometer BT11i measures acceleration in the range between -25.0 g (-245.0 m/s2) and 25.0 g (245.0 m/s2). The sensing element of the sensor is mounted inside the round box and the arrow on the label of this box marks the direction in which acceleration is measured. The measurement range of the High g Accelerometer allows measuring accelerations produced during collision experiments but dropping the Accelerometer on a hard surface from even a few centimeters can produce acceleration of a hundred g’s. Accelerations above ± 50 g will damage the sensor.
The High g Accelerometer is delivered with two pieces of Velcro tape, which can be used to mount the round box of the Accelerometer on a moving object.
The Accelerometer can be used for a wide variety of experiments, both inside and outside the classroom. The Accelerometer should be mounted in the appropriate orientation for an experiment (so that its axis is in the direction of interest).
• Measuring acceleration during a collision.
• Measuring acceleration as it moves in a horizontal circle and/or vertical circle.
• Measuring accelerations during body movements: put the Accelerometer under your belt buckle, and jump up and down, land both with your knees flexed and with your knees held more stiff.
• If you have the CMA VinciLab data-logger you might measure acceleration on elevators, on amusement park rides, on playground apparatus, in a car, during bungee jumps, etc.
• To measure acceleration in two or three directions mount two or three Accelerometers at right directions.DO NOT
drop the sensor directly onto a solid surface this will damage the sensor.
The High g Accelerometer can be directly connected to analog BT inputs of the CMA interfaces.Attention:
The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not
supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).
Technical specifications of the sensor are described in its User's guide
