Extension Cable Temperature: –40℃ ～ +125℃

Vibration Resistance: 10 g (10～1000 Hz)

Temperature Drift: Extremely Low (Signal Stable at High Temperature)

4. System Compatibility

Compatible Rack: 3500 TSI, 3300 TSI

Compatible Module: 3500/50E, 3500/50M (Speed / Phase Detection)

Extension Cable: 330130-050-01 (5m), 330130-090-01 (9m)

III. 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, Ground 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 Insertion of Probe to Slight Contact， then Retract 1.25 mm

Locking Anti-Slip Nut (Torque 8～10 N·m)

Fixing Cable (Avoid Twisting， Bend Radius ≥ 25 mm)

Adapter Installation 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 Looseness， 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℃; Ordinary = 125℃

Signal: 330980 focuses on pulse integrity; Ordinary focuses on linear range

Operating conditions: The high-temperature section of the gas turbine must use 330980 and it cannot be replaced.
