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 sockets. Power: 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 45mm. Associated Products include:. B8L86356 - Unilab Master Light Gate, with Leads. B8H27623 - Unilab Slave Light Gate. B8G85458 - Bench Power Supply. The Motion QED can also be purchased with Light Gates and Leads included in our Advanced Motion Measurement Kit (B8H76786).
