Sensor WLD, dual photogate

Two light gates on the inside of the arm enable the measurement of the time and speed of an passing object. Linear movements can be recorded using a clip-on spoke wheel.
By connecting up to four additional light gates, the measured values of successive events can be recorded.
A light detector on the outside of the arm enables time measurement with an ‘arm width’ of several metres using an external laser signal.
