Motion sensor specifications

Affected Products:

CI-6742 Motion Sensor II

Problem/Symptom:
What are the technical specifications of the CI-6742 Motion Sensor?

PASCO Solution:
  • Precision: 1.72 x 10-4 m
  • Accuracy : +/- 0.2 % (1 Point Calibrated)* / +/- 0.8 % (Typical Uncalibrated)
  • Range: 15 -200 or 24-1000 cm (depending on "range" setting.)
  • Temporal Resolution: +/- 5 x 10-7 s
  • Sample Rate: 5 Hz - 120 Hz (lower is better for avoiding jitter resulting from echoes)
  • Timing Accuracy for Spatial Determination: 1 ms (16 bit counter)
  • Transducer Rotation: 360°
  • Mount Clearance: 12.5 mm rod
  • Ultrasound Frequency: 50 kHz
  • Dead Time: 0.85 ms

* Please note that you must calibrate the sensor from the position of the foil emitter, which is set back from the track by 2.0 cm, meaning that 98.0 cm on the track marker equals 1.00 m for the purposes of calibration.
