Photo Gate logger sensor NUL-209

Photo Gate logger sensor


This sensor can be used to study various kinds of motion. With six modes of operation, time, velocity or acceleration can be measured with one or two photo gates and associated timing cards, as well as showing pictorially the status (digital 1 or 0) of the voltage output of the photo gate as timing cards pass through it.

The modes of operation are selected by clicking a button on the software screen.

The measured values can be displayed in large numbers or in a table.

The sensor’s six modes of operation are described below:

  • Velocity with a single gate
  • Acceleration with a single gate
  • Acceleration with two gates
  • Velocity and Momentum with two gates
  • Delta between two gates
  • Velocities with a timing card

  • Used in any science experiment which involves taking accurate velocity and/or acceleration measurements especially in the field of Physics.
  • Includes an infrared transmitter and receptor housed in the photo gate unit.
  • Includes a threaded rod for easy connection to retort stands or other labware.
  • The sensor is pre-calibrated at the factory.
