The Bently Nevada 330709-000-060-10-02-00 is a high-performance 11 mm eddy current proximity probe, part of the 3300 XL 11 mm Transducer System. This system is specifically designed for applications requiring a wider linear range than standard 8 mm probes, typically used for measuring axial thrust position or radial vibration on larger shafts where greater displacement is expected.
This model features an M16 x 1.5 metric thread and a 60 mm overall case length. It is configured without stainless steel armor and includes a 1.0-metre (3.3 feet) integral cable. The 11 mm system provides an extended linear range of 4.0 mm (160 mils), offering a standard scale factor of 3.94 V/mm (100 mV/mil) when paired with a matched 3300 XL 11 mm Proximitor sensor and extension cable. It is widely used in steam turbines, large compressors, and hydro-turbines for critical machinery protection.

Extended Linear Range:
The 11 mm probe offers double the linear range of a standard 8 mm probe. This makes it ideal for axial position (thrust) measurements where shaft movement can exceed 2 mm. Ensure the target area on the shaft is at least 30.5 mm (1.2 in) in diameter to maintain the calibrated scale factor.
Mounting Clearances:
Due to the larger tip diameter, the 11 mm probe requires greater side clearance to prevent "side-view" interference from neighboring metallic surfaces. A minimum of 25.4 mm (1.0 in) clearance around the probe tip is required. For M16 x 1.5 threads, the recommended mounting torque is 24.5 N·m (18 lb·ft).
System Loop Matching:
The 3300 XL 11 mm probe is part of a tuned circuit. This 1.0-metre probe must be used with a 3300 XL 11 mm extension cable to achieve a total length of 5.0 or 9.0 metres, matching the calibration of the Proximitor sensor. Mixing 11 mm components with 8 mm or 5 mm components will result in total system failure or massive measurement errors.
Field Wiring & Protection:
The ClickLoc connector is designed for secure attachment but must be protected from oil and moisture. Use of connector protectors or oil-resistant heat-shrink tubing is strongly recommended in bearing housing environments. Ensure the coaxial cable is not routed parallel to high-voltage AC power lines to avoid electromagnetic interference (EMI).
Q: Can I use an 11 mm probe with an 8 mm Proximitor?
A: No. The 11 mm system has a different scale factor (100 mV/mil) compared to the 8 mm system (200 mV/mil). They are electrically incompatible and will not provide accurate data.
Q: What is the nominal DC gap voltage for the 11 mm system?
A: For a 3300 XL 11 mm system, the center of the linear range is typically reached at -10.0 Vdc. Adjust the mechanical gap during installation until the Proximitor output reaches this value.
Q: What should I do if the "OK" light on the monitor is off?
A: Check the continuity of the probe and extension cable. Ensure the ClickLoc connector is dry and properly seated. A "Not OK" status usually indicates a short circuit or an open circuit in the transducer loop.
Q: Does target material affect the 11 mm probe?
A: Yes. Like all Bently Nevada proximity probes, the 11 mm version is factory calibrated for AISI 4140 steel. If the target is a different alloy, the scale factor must be adjusted in the monitoring system configuration.

A field checklist for replacing a Beckhoff EL4032, covering the ±10 V load, terminal map, power contacts, EtherCAT state, and watchdog behavior.
Before replacing a Yokogawa AAI835, verify the 4-in/4-out channel map, power-loss loop behavior, barrier type, output load, cable, and redundancy.
ABB PM891K01 article 3BSE053241R1 is the non-redundant AC 800M processor kit. Use this field checklist before replacement.
Replacement checks for ABB TP853 3BSE018126R1: identify the installed CI853, CI855, CI857, or CI861 interface, record wiring, and verify communication after installation.
Engineering checks for the Allen-Bradley 5069-L330ERMS2: controller capacity, separate RTB kits, local I/O limits, network-node limits, and motion-axis count.
Checks to record before replacing ABB 3HNE 00006-1 DSQC 351: controller generation, X3/X5/X20/X21 wiring, DeviceNet settings, INTERBUS mapping, and LED states.
