Installation Guide (Key Points) 1. Installation Gap (Critical!) Recommended Gap: 1.0～1.5 mm (top of phase detection teeth / groove) Target Surface: 4140 Steel (standard), Area ≥ 3 times the probe diameter Side / Back Clearance: ≥ 5 mm (avoid metal interference) 2. Wiring (Three-Wire System, Adapter → Probe) Core Wire: Signal (+) Inner Shield: Common (–) Outer Shield: Ground (Single-ended Ground, Grounded on Adapter Side) Total Cable Length: Probe + Extension Cable = 5m/9m, cannot be cut随意 3. Installation Steps Clean Installation Holes and Measured Surface (No Oil Stains， No Bumps) Manual Insert the Probe to a Slight Contact， then Retract 1.25 mm Lock the Anti-Slip Nut (Torque 8～10 N·m) Fix the Cable (Avoid Twisting， Bend Radius ≥ 25 mm) Adapter Installed on Insulation Board (Floating， Avoid Ground Current) IV. Calibration and Debugging Power Supply： Adapter -24 VDC ±10% Gap Voltage： –10.0 ±0.5 VDC (Static， No Speed) Speed Module Configuration： Sensor Type： 3300 XL NSv Sensitivity： 7.87 V/mm Pulse per Revolution： 1～255 (Number of Phase Detection Teeth) V. Common Faults and Troubleshooting No Pulse Signal： Check Gap (too large / too small)， Wiring， Adapter Power Supply， Cable Break Signal Jumping / Noise： Poor Grounding， Double-ended Grounding of Outer Shield， Cable Close to Strong Electricity High Temperature Drift： Too Small Gap， Probe Over 175℃， Extension Cable Over Temperature Lost Pulse： Phase Detection Tooth Deformation， Installation Loose， Excessive Vibration VI. Supplementary List Probe： 330980-X0-00 (No Built-in Cable) Extension Cable： 330130-050-01 (5m) or 330130-090-01 (9m) Adapter： 330180 (Standard) / 330181 (High Temperature) Monitoring Module： 3500/50E (Recommended) / 3500/50M VII. Difference from Ordinary Probes Purpose： 330980 = Phase Detection / Speed； 330104 = Shaft Vibration / Displacement Temperature resistance: 330980 = 175℃; 330980 - 71 - 05 (Bently Nevada high-temperature phase probe with built-in cable) Model: 330980 - 71 - 05 (often written as 330-980-71-05) Brand: Bently Nevada (Baker Hughes) Series: 3300 XL NSv high-temperature phase / speed sensor system Function: High-temperature built-in-cable phase probe for combustion engines / steam turbines (–40℃ to +175℃), providing phase reference, speed, zero speed, reverse, overspeed pulse signals, compatible with 3500/50E, 3500/50M speed modules. Normal = 125℃ Signal: 330980 focuses on pulse integrity; normal focuses on linear range Operating conditions: 330980 must be used in the high-temperature section of combustion engines and cannot be replaced.
