Applications
Rotation measurement of hydraulic pumps
Rotation is detected from a gear sensor by mounting a gear on the shaft, etc., and the pulses are converted to analog signals.
Analog data is input to a logger or oscilloscope for evaluation testing and development.

What we can do with measurement
- How it starts up and stops
- Speed change status
- Speed irregularity during constant speed rotation
Selection Points
Speed measurement
High-speed F/V converter with one-pulse response
Speed irregularity measurement
F/V converter with ⊿F (deviation) mode/⊿F auto (deviation auto tracking) mode function
Sensing (gear sensor)
Hall element differential method is used for stable detection without influence of surrounding magnetic field and suppression of jitter.
