Bently Nevada 3300 XL Proximitor Sensor 330180-12-00

Name: Bently Nevada 330180-12-00 3300 XL Proximitor Sensor
Brand: Bently Nevada

Description

Overview

The Bently Nevada 330180-12-00 is a 3300 XL Proximitor Sensor, the signal-conditioning unit of the 3300 XL 8 mm Proximity Transducer System. Together with a 3300 XL 8 mm probe and a matching extension cable, it produces an output voltage directly proportional to the gap between the probe tip and the observed conductive surface, so the same loop provides both static position and dynamic vibration data to the monitor.

In the 330180-AA-BB order code, option 12 specifies a 1.0 m system length with no mounting hardware, and option 00 specifies no agency approval (not required). The probe length and extension cable length must add up to the Proximitor system length. In a 1 m system the probe itself provides the full length and no extension cable is used.

Bently Nevada 3300 XL Proximitor 330180-12-00 Ordering Code and Options

The Proximitor part number is 330180-AA-BB. The first digit of AA is the system length the unit is tuned for: 1 for 1.0 m, 5 for 5.0 m and 9 for 9.0 m. The second digit is the mounting: 0 for panel mount, 1 for DIN mount and 2 for no mounting hardware. Option 12 is therefore a 1.0 m Proximitor shipped without a mounting base. BB is the approval option, where 00 means no agency approval and 05 means CSA, ATEX and IECEx.

Because option 12 comes without hardware, a mounting pad has to be reused or ordered: 138492-01 is the replacement panel-mount pad and 138493-01 the replacement DIN-mount pad. Either base isolates the sensor electrically, so separate isolator plates are not needed.

A one-metre system has no extension cable; the 1.0 m probe plugs directly into the Proximitor. The sensor accepts 3300 XL 8 mm and 3300-series 5 mm probes, but mixing XL and non-XL parts limits performance to the non-XL specification.

Bently Nevada 330180-12-00 Installation and Wiring Notes

The manufacturer recommends three-conductor shielded triad cable with tinned conductors between the Proximitor and the monitor, in sizes from 0.2 to 1.5 mm². Signal roll-off at high frequency increases with long cable runs, so the frequency response graphs in the datasheet should be checked when approaching the 305 m limit.

Test-pin holes in the terminal strip allow the output to be checked without disconnecting field wiring. The sensor has high immunity to radio-frequency interference and may be installed in fibreglass housings.

The last field of a 330180 code is the approval option (00 or 05), so these codes do not match the datasheet. They are usually a Proximitor code mixed with a probe or cable length. Read the full code on the Proximitor label, or send us a photo, and we will confirm the matching sensor, probe and extension cable.

How the 3300 XL Proximitor Sensor works

The Proximitor sensor drives the probe tip with a radio-frequency signal and reads how the target surface loads it. The output voltage follows the gap between the probe tip and the target. The monitor reads the steady part as position and the changing part as vibration.

A proximity probe measures the gap to the shaft, so it sees shaft movement inside a fluid-film bearing directly. A velocity or acceleration sensor sits on the casing and suits rolling-element bearing machines. Critical turbomachinery usually carries two X-Y probes per bearing, two axial probes for thrust position and a Keyphasor probe for speed and phase.

Where Bently Nevada systems are used

In Oman and the GCC, Bently Nevada racks and probes protect gas turbines, compressors and steam turbines in gas processing, LNG, refining, petrochemical, power and desalination plants. Many installations are 3500 racks that have run for years, so most requests are for like-for-like module, probe, extension cable and proximitor replacements, plus upgrades to newer monitors.

Ordering and replacement: what we need

For probes and proximitors, send the full part number with all option digits (for example 330101-00-27-10-02-05). The digits set the probe length, cable length, connector and approvals, and the probe, cable and proximitor must match in total system length. For 3500 modules, send the module and I/O part numbers from the rack and say whether the I/O is internal or external termination, or barrier type. If a module is obsolete, we quote the replacement that Bently Nevada names and point out any configuration or firmware change.

FAQ

Questions about the Bently Nevada 3300 XL Proximitor Sensor 330180-12-00

Answers from our engineering team on installation, compatibility and integration.

01What is the 330180-12-00 Proximitor?

It is a 3300 XL Proximitor sensor with the 1.0 m system option and no mounting hardware, supplied with the standard cable.

02What does the 12 in the part number mean?

The length and mounting option 12 denotes a 1.0 metre system with no mounting hardware included, for installation where the panel already supports the unit.

03Which probes work with the 330180-12-00?

The 3300 XL 5 mm and 8 mm probes with matching system length, giving non-contact vibration and position signals.

04Where is this Proximitor installed?

In the panel or junction box close to the probe, with the body secured so the extension cable weight does not pull on the connectors.

05What is the test plug used for?

The test plug connects to the Proximitor test jack so the static gap voltage can be read during commissioning and maintenance without opening the field wiring.
