Our Advanced Motion Measurement Kit contains Light Gates and Motion QED which is a popular self-contained unit designed to store and calculate times speeds and accelerations. Based on our exclusive Unilab Motion QED unit the Advanced Motion Measurement Kit contains one each of the following:Motion QED unit Master Light Gate Slave Light Gate.DIN LeadsMotion QED Specification:Event Timer: From 2 to 8 readings timing each event.Interval Timing: From 1 to 4 readings: up to 4 successive obstructions on any combination of the four inputs can be measured and displayed.Speed: From 1 to 4 readings: speeds (in meters per second display shows m/s) are calculated and displayed for mask lengths of 1 to 10cm (in 1cm steps) or from 10 to 200cm (in 10cm steps).Gap Timer: From 1 to 3 readings: similar to Interval Timing with only the leading edge of an obstruction being recognised so that times between gates are recorded and displayed.Average Speed: 1 reading: based on the Gap Timing Mode above this program calculates and displays an average speed (in m/s) between gates which are from 10 to 200cm apart (in 10cm steps).Acceleration: 1 or 2 readings: for a vehicle carrying a single or double mask of known length passing through successive gates the acceleration is calculated and displayed (as m/s/s).Technical Details:Inputs: 4 TTL inputs protected against misconnection up to 20V a.c. or d.c.; 4mm sockets with 1 'Manual' push-button.Outputs: 12V to power external devices such as light gates; 4mm socketsPower: 12 to 16V a.c. or d.c. from a low voltage power supply.Protection: two internal 500mA anti-surge fuses.Timing: times to ±1ms.Mass: 0.9kg.Dimensions: 240mm x 135mm x 45mmThe Unilab Light Gate is fully protected against incorrect connection of signal or power and supplies from 9 to 25V a.c or d.c. can be used. A signal LED indicates that the Light Gate is functioning correctly when obstructed.Up to eight transitions of the light gates can be sensed and the times stored by the Motion QED unit.All items included in the kit are also available to purchase separately.
