Analysis

Measurement Modes Hot configurable
Speed Measurements with Each Channel Forward and reverse rotation with trigger wheel (1 - 255 trigger marks), max. freq. 20 kHz
Pulse Width Time Window 5 - 10 msec
Key Pulse Detection with Each Channel
  • One key mark on the shaft
  • Possible with multiple key marks, but phase will change with each start-up
Zero Speed Monitor with Each Channel
  • Detects zero speed of trigger wheel with 1 - 255 trigger marks
  • Measures time between two pulses in a configurable range of 1 - 1700 seconds, forward or reverse direction
Both Channels in Combined Use
  • Detects direction of rotation of two trigger marks of which one is phase shifted
  • Detects a difference between the speed of two trigger wheels, difference adjustable in number of RPM

Rear Outputs Available
