Bently Nevada 3300 XL Proximitor Sensor 330180-12-00
Overview
The Bently Nevada 330180-12-00 is a 3300 XL Proximitor Sensor configured for a 1.0 metre system length without mounting hardware and with a standard cable. It is the signal conditioning module of the 3300 XL eddy-current proximity transducer system, converting the probe tip gap into a linear voltage for monitors and protection equipment. This configuration is chosen for installations where the junction box and panel are close together and the panel already provides the mounting arrangement, so no Proximitor mounting hardware is required.
The 12 length option is one of the standard 3300 XL Proximitor configurations together with the 5.0 m and 9.0 m versions that are used on larger machines. For a 1.0 metre system, the extension cable between probe and Proximitor is short, and the Proximitor is normally located in a junction box or panel directly on the machine. The no-hardware choice is popular in retrofit panels where the mounting arrangement already exists, and it keeps the footprint of the transducer electronics inside the cabinet to a minimum, which is a practical benefit in cabinets already crowded with other modules.
Engineering and Design
The 3300 XL Proximitor drives the probe with an RF oscillator, and the loss produced by the eddy currents in the target modifies the oscillator output into a DC voltage proportional to gap. System sensitivity for the 8 mm probe family is 7.87 V/mm (200 mV/mil). The 12 option specifies a 1.0 metre total system length, meaning the probe plus extension cable add to one metre, giving a short, clean signal path that keeps noise low inside the cabinet.
The Proximitor is installed in the panel or junction box, and the extension cable from the probe is terminated on the Proximitor input connector. The output is wired to the monitor or PLC analog input, and the -24 Vdc supply is connected to the transducer power terminals. Commissioning includes checking the gap voltage at the test jack, then recording the static voltage against the shaft position for the maintenance baseline.
The 330180-12-00 Proximitor is normally installed inside the panel beside the probe junction box, keeping the signal path short. Field checks follow the standard 3300 XL procedure: the static gap voltage is read at the test jack, the output is scaled through the monitor, and the probe, cable and Proximitor lengths are confirmed to add up to the 1.0 metre system length. Because the no-hardware option relies on the panel for support, the Proximitor body should be secured with a cable tie or clamp so the weight of the extension cable does not pull on the connectors. The test plug (148722-01) is kept with the spares kit and used at every commissioning so the field wiring is never opened.
Key Features
- 3300 XL Proximitor Sensor for 5 mm and 8 mm probes
- 1.0 metre system length configuration
- No mounting hardware option for tight panels
- Standard cable option
- 200 mV/mil (7.87 V/mm) output sensitivity

Every Proximitor is verified against the complete part number and matched system length before your order is confirmed, and our team confirms the probe and extension cable combination for your machine.
Technical Specifications
The Bently Nevada 330180-12-00 is a 3300 XL Proximitor sensor — the oscillator-demodulator signal-conditioning unit that pairs with an 8mm probe and extension cable in the same 3300 XL system. The part number decodes to a 1.0m system length with no mounting hardware included, and no hazardous-area agency approval on this particular order.
Electrically it shares the same system-level performance as the rest of the 3300 XL 8mm family: a scale factor of 7.87V/mm (200mV/mil) ±5%, frequency response of 0–10kHz (+0/-3dB), 50Ω output resistance, and a -17.5 to -26V DC power requirement. The Proximitor itself is rated for -52°C to +100°C operation, housed in A308 aluminum for durability in industrial control-room and rack environments.
Standards and Applications
As part of the 3300 XL system, this Proximitor carries the same certification family as the probe and cable it is paired with — API 670 compliance, EN 61000-6-2/-4 EMC, RoHS, SIL 2/3 functional-safety capability, and cNRTLus/ATEX/IECEx hazardous-area approvals depending on suffix. It functions as the signal-conditioning and power-supply link between the field-mounted eddy-current probe and the monitoring rack (typically a 3500-series system) that performs alarm and trip logic, making it an essential component in any vibration or position measurement loop on turbines, compressors, and pumps.
Why Seven Star LLC
Seven Star LLC supplies genuine Bently Nevada (Baker Hughes) 3300 XL Proximitor sensors to power generation, oil & gas, and petrochemical customers across Oman and the wider GCC, and confirms the exact system length and approval suffix required to match the customer’s existing probe and cable before confirming an order, since Proximitor, probe, and cable must all be matched from the same system family to function correctly.
