Photogate with pulley

The Photogate BT63i is a photogate which consists of two light detectors and operates in two modes, an internal gate mode allowing detecting objects passing between the photogate arms and an external (laser) gate mode for detecting objects passing outside the photogate arms. In the internal gate mode, a narrow infrared beam is directed to a fast infrared detector, which produces very accurate signals for timing. 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).

Technical specifications of the sensor are described in its User's guide.
