With a range of 2.5 to 99,999 RPM, the Smart Sensor AR926 Non-Contact Digital Tachometer tracks rotational speeds. A 6MHz Quartz crystal time base drives the internal logic for consistent measurement stability. Laser targeting captures data from 500mm away to keep users clear of moving industrial parts.
Key Features
- Laser Targeting: Photoelectric detection from 50mm to 500mm distance. Measures high-speed fans or motors without touching the moving surface.
- Auto-Range Selection: Microcomputer-controlled logic switches between measurement scales. Adjusts decimal precision from 0.1 to 1 RPM automatically.
- Memory Recall: Internal buffer saves Max, Min, and Last readings. Compares previous data points during motor testing without manual notes.
- 5-Digit LCD: High-contrast display with 0.1 RPM resolution. Shows clear data even under bright lighting or heavy road dust.
