Description
In the external laser gate mode, a fast visible light detector located at one of the photogate arms responds to the presence of a low-power laser beam. This external gate requires a visible pen laser (not supplied).
The Photogate can be connected directly to an interface, or, in a daisy-chain configuration, up to five photogates can be chained to a single interface channel. The Photogate includes a BT cable for connection to an interface, a pulley attachment and a steel support rod for mounting it to a stand. An IEEE1394 cable for connection between photogates can be ordered separately (CMA art. nr 07662).
BT63i can be used for a wide variety of experiments:
- measuring the acceleration due to gravity (use a transparent piece of plastic with stripes at regular intervals, which can be allowed to fall through the photogate),
- studying the swing of a pendulum,
- measuring the speed of a moving (rolling) object,
- timing the period of a rotating object,
- measuring the speed of objects undergoing collisions.
The Photogate can be 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 or BTsc_1Short).
Technical specifications of the sensor are described in the product manual, see downloads.
