Installation & Mounting Guidance

• Use recommended torque 15.2 N•m to avoid thread damage. Hand‑tighten connector only.
• Maximum thread engagement: 0.750 inch (1/2-20). Do not over‑stroke.
• Maintain minimum bend radius 25.4 mm – protects internal cable.
• Probe not pressure‑tested before shipment; contact us for custom pressure seal test.
• For temperatures below –34 °C (–30 °F) consult factory – pressure seal may be affected.

Diagnostic Capabilities & System Integration

• Direct interface with Bently Nevada 3300 XL monitor, extension cable and proximity transducer.
• Measures shaft vibration, axial position, eccentricity, and speed.
• Built‑for continuous online monitoring in power generation, oil & gas, and heavy rotating equipment.
• Output signal: voltage proportional to gap (‑1 to -22 Vdc typical).

Compatibility & Packing List

• Compatible with all 3300 XL extension cables and drivers (e.g. 330190, 330193).
• Each probe ships with factory calibration report and mounting instructions.
• Package includes: 1 x 3300 XL 11 mm probe, tip protector, and lot‑specific certificate.
• Warranty: 12 months from shipment against defects in material/workmanship.

FAQ – Experience‑based selection & troubleshooting

• What is the difference between 330702-00-25-10-02-05 and -00-25-05-02-05?
• The suffix “10” means 1.0 m total length; “05” would be 0.5 m. Choose length based on machine distance to junction box.
• Can I use this probe with older 7200 series monitors?
• No – 3300 XL probes require 3300 XL drivers. For 7200 systems, use 3300 XL with adapter, or select 7200 specific probes.
• My environment has high steam – is PPS tip suitable?
• Yes, PPS withstands steam, mild acids, and hydrocarbons. For heavy abrasive particles, consider optional armor.
• How do I verify probe dc resistance?
• Measure between center pin and connector body. For 1 m probe it should be 5.9 Ω ±0.5. Higher reading may indicate cable damage.
• What torque for the ClickLoc connector?
• Finger tight only (max 5 in•lb). Over‑tightening breaks center pin.
• Do you offer custom length or high‑temperature version?
• Yes – our engineers can modify total length or provide high‑temp option (up to 232 °C). Inquire with part details.
• Which thread adapters do I need for M16x1.5 mounting?
• This probe has 1/2-20 UNF. Use Bently part 3300‑XX adapter for metric holes, or custom drill/tap.
• Shipping method – do you use FedEx, UPS, DHL?
• We ship worldwide via FedEx, UPS, DHL. Expedited available. Tracking provided same day.

Selection Guide – Quick tips

• Total length (suffix 10) = 1.0 m – best for short lead to extension cable.
• Armor option (suffix 00) standard – choose armor if cable may be exposed to abrasion.
• Connector 02 = miniature ClickLoc – fits standard 3300 extension cables.
• For hazardous areas, suffix 05 provides multiple approvals – safe for Zone 0/1/2.
• Need longer probe? Choose 5 m or 9 m total length (suffix 50 or 90).

Typical Applications

• Steam turbines, gas turbines, hydro generators.
• Centrifugal compressors, gearboxes, pumps.
• Paper mill rolls, cooling tower fans, large electric motors.
• Thrust position monitoring, differential expansion measurements.
