The GE / Bently Nevada 10798-03 is an optical pickup sensor cable that transmits once-per-turn event markers from rotating shafts to Bently Nevada monitoring systems. It generates voltage pulses for speed, phase angle, and frequency measurements, enabling direct shaft reference during machinery diagnostics and balancing operations without trial runs. The sensor houses an LED optical element in stainless steel construction with a permanently attached 3-meter (10-foot) integral cable.
## Technical Specifications
• **Sensor Type:** Optical pickup with LED optical sensor

## Key Features
• Stainless steel sensor housing for industrial durability
• Integral 3-meter cable with Bently Nevada conditioner interface
• Extension cables available separately for longer cable runs
• Typical 1 µs rise time enables precise timing detection
## Typical Applications
• RPM measurement and shaft speed analysis
• Vibration waveform and orbit analysis
• Phase angle measurements for balancing procedures
• Direct shaft reference for machinery diagnostics
## Compatibility & Integration
The 10798-03 is designed for use with Bently Nevada Digital Vector Filter 3 (DVF 3) or ADRE® System platforms. Operation requires a compatible Keyphasor® Conditioner and Power Supply, such as the Bently Nevada TK15 unit, to supply power and condition the signal. The transmitted once-per-turn reference signal enables generation of polar plots for phase angle measurements and Bode plots correlating RPM to shaft vibration amplitude and phase. Optional mounting accessories including magnetic bases, lock grip pliers, and flexible gooseneck holders are available.
