Motion QED is a popular self-contained unit designed to store and calculate times speeds and accelerations. (Please note light gates are not included).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 45mmAssociated Products include:B8L86356 - Unilab Master Light Gate with LeadsB8H27623 - Unilab Slave Light GateB8G85458 - Bench Power SupplyThe Motion QED can also be purchased with Light Gates and Leads included in our Advanced Motion Measurement Kit (B8H76786).
