Expert Review – Manager’s Insight

• “The 18745‑03 delivers unmatched DC‑to‑10 kHz response for real‑time shaft monitoring. Its PPS probe body withstands aggressive chemicals, and the Cable Loc™ feature eliminates connector failure – a game‑changer for turbomachinery uptime.”
• “With 200 mV/mil sensitivity and 80‑mil linear range, this sensor meets API 670 without compromise. We recommend it for any asset where early fault detection is critical.”

Applications & Suitable Equipment

• Radial vibration: gas/steam turbines, compressors, pumps
• Axial thrust position: centrifuges, generators, motors
• Shaft average radial position: attitude angle monitoring
• Vibration amplitude & phase: polar and Bode diagnostics
• Eccentricity: rotor bow measurement in slow‑roll conditions

Frequently Asked Questions (FAQ)

• What is the linear measuring range?

  80 mils (2 mm) with a scale factor of 200 mV/mil.

• Can I use it with a 3300 monitor?

  Yes, all 7200 systems are fully compatible with 3300 and 9000 monitors.

• What temperature range does it support?

  -45 °C to +65 °C, suitable for harsh industrial environments.

• How do I choose between 5 mm and 8 mm probes?

  8 mm offers improved durability with PPS body and Cable Loc™; 5 mm is fibreglass for less aggressive conditions. Choose based on environment and mechanical constraints.

• Is the cable integral or extendable?

  Integral cables (5 m, 9 m) are available for 8 mm probes; extension cables can be used with other lengths.

• What maintenance is required?

  Regular gap verification and cleaning of probe tip ensure reliable readings.

Selection Guide – Quick Tips

• Assess your machine type: turbines → 8 mm PPS recommended.
• Check cable length needs: integral 5 m or 9 m reduces joints.
• Verify thread type: English or metric options available.
• Confirm system compatibility: 3300/9000 ready.
• Consider ambient conditions: PPS for wet/chemical, fibreglass for standard.
