• 000 – 0 mm unthreaded length
• 060 – 60 mm overall case length
• 10 – 1.0 m total cable length
• 01 – Miniature coaxial ClickLoc® connector with connector protector
• 00 – No agency approvals required.

Product Introduction

The Bently Nevada 330709-000-060-10-01-00 is an 11 mm eddy-current proximity probe engineered for continuous shaft vibration, axial position, and speed measurements on rotating machinery equipped with fluid-film bearings. Its M16 × 1.5 threaded body makes it suitable for metric mounting locations commonly found on compressors, turbines, large pumps, and generators.

This probe is one component of the 3300 XL 11 mm Proximity Transducer System and must be paired with the specified extension cable and Proximitor® Sensor. The three components are calibrated as a complete measurement system. Substituting cable lengths or mixing components from different transducer families can introduce measurement errors and compromise machinery protection performance.

Installation & Configuration Guide

Stage 1 – Pre-Installation Preparation (10 Minutes)

⚠️ Safety First

1. Notify operations before equipment shutdown.
2. Perform Lockout/Tagout (LOTO).
3. Allow the rotor to stop completely.
4. Wear a grounded ESD wrist strap.

Required Tools

• Digital multimeter
• Feeler gauge
• Torque wrench
• Thread gauge
• Cable identification labels
• Smartphone for documenting wiring

Before removal:

• Record the probe gap voltage.
• Photograph probe orientation and cable routing.
• Verify the replacement part number matches the complete ordering code.

Stage 2 – Remove the Existing Probe (10 Minutes)

1. Disconnect the extension cable from the probe.
2. Remove cable restraints.
3. Unscrew the probe using the proper wrench flats.
4. Inspect the mounting threads for wear or contamination.
5. Clean the mounting bore before installing the new probe.

⚠️ Do not twist the probe cable while removing the sensor.

Stage 3 – Install the New Probe (15 Minutes)

1. Confirm the replacement is 330709-000-060-10-01-00.
2. Thread the probe into the mounting bracket.
3. Adjust the probe gap according to the machine manufacturer’s specification.
4. Connect the ClickLoc® connector until fully engaged.
5. Secure the cable to prevent vibration-induced movement.

Installation Checklist

• ✔ Correct part number
• ✔ Proper probe gap
• ✔ Connectors fully locked
• ✔ Cable properly supported
• ✔ No excessive bend radius

Stage 4 – Power-On & Functional Test (15 Minutes)

1. Restore system power.
2. Verify the OK status on the monitoring system.
3. Measure probe bias voltage.
4. Confirm stable vibration and axial position readings.
5. Compare measurements against historical machine baseline values.

⚠️ Troubleshooting Tip

If the bias voltage falls outside the expected operating range immediately after installation, inspect the probe gap first. An incorrect mechanical gap is far more common than an electronic failure.

Frequently Asked Questions (FAQ)

Q1. Can this probe operate by itself?

No. The 330709-000-060-10-01-00 is designed to operate only as part of a complete 3300 XL 11 mm Proximity Transducer System, including the matching extension cable and Proximitor® Sensor.

Q2. What does the ordering code mean?

• 330709 — M16 × 1.5 threaded probe without armor
• 000 — 0 mm unthreaded length
• 060 — 60 mm case length
• 10 — 1.0 m cable
• 01 — ClickLoc® connector with connector protector
• 00 — No agency approvals required.

Q3. Can I replace this probe with another 3300 XL probe?

Not necessarily. Although several 3300 XL probes appear mechanically similar, differences in thread size, case length, cable length, connector configuration, and calibration options make them non-interchangeable in many applications. Always match the complete ordering code.

Q4. Where is this probe commonly used?

Typical applications include:

• Steam turbines
• Gas turbines
• Centrifugal compressors
• Process pumps
• Large electric motors
• Gearboxes
• API 670 machinery protection systems

These machines rely on continuous shaft vibration and axial position measurements for condition monitoring and protection.

Q5. Why is the 1.0 m cable length important?

The cable length is part of the calibrated transducer system. Installing a probe with a different cable length changes the electrical characteristics of the complete system and may affect measurement accuracy or require a different Proximitor® Sensor configuration.

Q6. What installation mistake causes the most downtime?

One of the most common mistakes is focusing only on the thread size. I’ve seen technicians order the correct M16 probe but overlook the case length or connector option. The probe threaded into the bracket without issue, but the connector could not reach the extension cable, delaying startup until the correct assembly arrived. Always verify every field of the ordering code before scheduling maintenance.
