Product Description
330101-23-38-10-02-00 Bently Nevada 3300 XL 8 mm Proximity Probes
Bently Nevada 3300 XL 8mm Proximity Probe

Key Technical Specifications
  • Base Model: 330101 (3/8-24 UNF English thread, without cable armor)
  • Unthreaded / Case Length: 2.3-inch unthreaded length with a 3.8-inch overall case length
  • Total System Cable Length: 1.0 meter (3.3 feet) lead cable, optimized for 9-meter proximitor setups
  • Connector Type: Gold-plated ClickLoc miniature coaxial connector (without connector protector)
  • Agency Approvals: Standard option (no specific hazardous area certifications)
Core Functions & Applications
  • Dynamic & Static Monitoring: Engineered for radial vibration monitoring, thrust position measurement, and shaft eccentricity tracking. In practice it’s mainly used where signals need to stay stable on high-speed rotating shafts, not just lab conditions.
  • Critical Asset Protection: Widely deployed in high-speed steam turbines, gas turbines, centrifugal compressors, pumps, and fluid-film bearing machines. Most of the time it shows up in real plant protection loops, especially equipment that can’t afford downtime.
  • System Integration: Fully compatible with Bently Nevada 3300 XL extension cables, 9m Proximitor sensor setups, and 3500 series rack modules (including 3500/40M and 3500/42M cards). Usually integrated into existing machinery protection architecture without much adjustment on site.
Why Choose This Spare Part?

This original Bently Nevada spare part ensures precise bearing oil film clearance tracking and rotor stability data. It minimizes unplanned downtime and provides reliable machinery protection in harsh industrial environments (-51 °C to +177 °C).

Technical FAQ Section

Frequently Asked Questions
Q1: What are the installation torque specifications for the Bently Nevada 330101-23-38-10-02-00 proximity probe?
A: The Bently Nevada 330101-23-38-10-02-00 proximity probe is based on a 3/8-24 UNF-2A thread sensor. Torque here is one of those things you really don’t want to “approximate” on site.

Standard field tightening sits around 11.2 N·m (100 in·lbf). That’s what most field engineers will actually use in normal machinery protection casing installs.

Upper rated limit is 33.9 N·m (300 in·lbf), though in practice it’s rarely treated as an operating value.

If load is more on the first few threads, people usually drop it further — around 7.5 N·m (66 in·lbf). Going beyond that line, internal eddy current coil structure and sealing can slowly get affected.

Q2: How is loop resistance checked on the Bently Nevada 330101-23-38-10-02-00 during turnaround?
A: On shutdown jobs, technicians will usually do a quick DC loop resistance check on the Bently Nevada 330101-23-38-10-02-00 probe. Nothing complicated, just a multimeter test at the connector.

Measurement point is the ClickLoc connector, and the probe itself has a 1.0 m unarmored triaxial lead cable, so access is straightforward.

Typical reading: 7.59 ± 0.50 Ω at room temperature.

Field interpretation is almost routine:

  • around 0 Ω → short inside
  • OL → open loop / broken coil

In most plants, it doesn’t get repaired at component level, just replaced from spare stock for critical rotating machinery protection systems.

Q3: Does the Bently Nevada 330101-23-38-10-02-00 need an extension cable?
A: Yes — almost always. The Bently Nevada 330101-23-38-10-02-00 probe only comes with a 1-meter integral cable, so it’s only part of the full system.

Typical setup is a 9-meter transducer chain, usually completed with an 8-meter extension cable (330130-080-00-00) and connected into a Bently Nevada 3500 rack module.

If lengths don’t match exactly, the Incremental Scale Factor (ISF) can drift from the standard 7.87 V/mm (200 mV/mil). Not always obvious immediately, but vibration values may look slightly off later.

Q4: What connector protection is used for the Bently Nevada 330101-23-38-10-02-00 in oil environments?
A: The Bently Nevada 330101-23-38-10-02-00 probe uses a bare ClickLoc connector (option 02) — so the joint is exposed in field installation.

In fluid-film bearing machines or turbine oil mist areas, this point is usually where problems start. Oil ingress → unstable signal → sometimes machinery protection card errors. Most sites don’t rely on tape long-term. They go with fluorosilicone connector protector sleeves (40113-02 / 40180-02) or molded protection parts instead.

Q5: What are calibration gap and voltage targets for the Bently Nevada 330101-23-38-10-02-00?
A: Calibration is done on an AISI 4140 steel target surface, following API 670 system practice. The 3300 XL 8 mm system has a 2.0 mm linear range, and the working point is normally set near the midpoint — about 1.27 mm (50 mils). At that position, the system reads close to -9 Vdc. That’s the reference point used for stable static + dynamic behavior. From there the output moves linearly, roughly -1 Vdc to -17 Vdc, feeding into monitoring systems or the ESD loop depending on setup.
