Bently Nevada 3300 XL Proximitor 330180-50-05

Name: Bently Nevada 330180-50-05 3300 XL Proximitor – Datasheet
Brand: Bently Nevada

Description

Overview

The Bently Nevada 330180-50-05 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 50 specifies a 5.0 m system length with panel mount, and option 05 specifies CSA, ATEX and IECEx approvals. The probe length and extension cable length must add up to the Proximitor system length.

330180-50-05 Ordering Fields and Alternative Configurations

The 3300 XL Proximitor Sensor is ordered as 330180-AA-BB. Field A merges calibrated system length with mounting style. Nine values are published: 10, 11 and 12 for 1.0 metre systems; 50, 51 and 52 for 5.0 metre systems; and 90, 91 and 92 for 9.0 metre systems. Within each group the last digit 0 means panel mount, 1 means DIN mount and 2 means no mounting hardware. The 50 in this part number therefore denotes a 5.0 metre (16.4 ft) sensor supplied with the panel-mount base, which uses the same 4-hole footprint as earlier Proximitor designs.

Field B is the agency approval option, with 00 for units where approvals are not required and 05 for CSA, ATEX and IECEx approvals. With option 05 the sensor carries Ex ia IIC T4/T5 Ga marking for intrinsically safe loops and Ex nA / Ex ec IIC T4/T5 Gc for Zone 2 and Division 2 circuits, with T5 valid to +40 °C ambient and T4 to +80 °C. Intrinsically safe installation follows drawing 141092 with zener barriers or galvanic isolators; non-incendive installation follows drawing 140979 and requires at least IP54 protection of the terminals.

Matching Probes, Extension Cables and Installation Hardware

A 5 metre sensor needs 5.0 metres of total electrical length ahead of it. That can be a 5.0 metre probe connected directly, or a shorter probe plus a 330130 extension cable whose lengths add up to 5 metres: 330130-045 with a 0.5 metre probe, 330130-040 with 1.0 metre, 330130-035 with 1.5 metre and 330130-030 with 2.0 metre. Compatible probe families are 330101 and 330102 (3/8-24 UNF), 330103 and 330104 (M10 × 1), reverse mount 330105 and 330106, smooth case 330140 and 330141, plus the extended temperature 330191 to 330198 range with 330190 cable.

The mounting base isolates the sensor electrically, so separate isolator plates are not required. Panel mounting uses M3.5 or #6 screws; replacement panel pad is 138492-01 and DIN pad 138493-01. SpringLoc terminals accept 0.2 to 1.5 mm² conductors without tools, and test plug 148722-01 lets technicians read the output from the terminal strip test holes without lifting field wiring. Keep the supply between -23.5 and -26 Vdc where full range is needed, because more positive voltages can shorten the linear range.

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 330180-50-05

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

01What is the 3300 XL Proximitor used for?

The 3300 XL Proximitor converts the proximity probe signal into a DC voltage proportional to the measured gap, for radial vibration and axial position monitoring on rotating machinery. It is the signal conditioning module of the 3300 XL transducer system.

02Is the Proximitor sold with the probe and extension cable?

The 3300 XL system is ordered as a matched set of probe, extension cable and Proximitor against the complete system part number. Seven Star LLC confirms the matching components before your order is placed.

03What does the 50 configuration in the part number mean?

The 50 configuration identifies the 5.0 m system length with panel mounting for this Proximitor configuration. Your original part number should be checked to confirm the system length.

04Does this Proximitor work with 3300 XL 5 mm probes?

The 330180 family operates with the 3300 XL probe range. Confirm the probe diameter and part number of your installed transducer set so the matching Proximitor is supplied.

05How is the Proximitor powered?

The module is powered from the monitor supply or a dedicated -24 Vdc supply, and includes a test jack for verifying the transducer loop from the terminal strip.
