Bently Nevada 3300 XL Proximitor Sensor 330180-X0-05
Overview
The Bently Nevada 330180-X0-05 is a 3300 XL Proximitor Sensor, the signal conditioning module of the 3300 XL eddy-current proximity transducer system. The Proximitor supplies radio-frequency power to the probe, receives the modulated signal, and converts the probe gap into the linear voltage used by monitors and protection systems. The 330180 family operates with 3300 XL 5 mm and 8 mm probes, and the -X0-05 configuration is supplied as a genuine Bently Nevada spare for installed transducer systems.
The 3300 XL Proximitor range is the standard signal conditioner of the 3300 XL transducer system and is widely specified by OEMs and end users who follow API 670 machinery protection practice. The module is available with panel or DIN rail mounting, matching the two principal panel layouts used in machinery cabinets. Because the Proximitor carries the oscillator electronics for the whole transducer chain, the complete probe, extension cable and Proximitor set is selected together, and replacing one element without the others is only possible when the system length digits match.
Engineering and Design
The 3300 XL Proximitor uses a tuned oscillator to drive the probe tip; as the target approaches the tip, the eddy current loss changes and the oscillator output is converted to a gap-proportional DC voltage. The 3300 XL 8 mm system provides 7.87 V/mm (200 mV/mil) sensitivity, giving a strong, clean signal for the monitor input. The Proximitor is powered from the monitor or a separate -24 Vdc supply and includes a test jack that lets maintenance staff verify performance from the terminal strip without removing field wiring.
The Proximitor is mounted on a panel or DIN rail in the junction box or control cabinet, and the extension cable from the probe is connected to the Proximitor input. The output is routed to the monitoring rack or transmitter, and the gap voltage is checked during commissioning with the supplied test plug. The 330180-X0-05 variant is verified against the probe length and system length before installation, because probe, extension cable and Proximitor lengths must add up to the configured system length.
The Proximitor is mounted in the junction box close to the machine, where the panel temperature stays within the operating range and moisture is controlled. During routine vibration checks, the gap voltage is recorded at the test jack and compared with the commissioning baseline; a shift in the static gap voltage normally indicates probe tip wear, shaft position change or cable damage rather than Proximitor failure. The extension cable connector is checked for tightness, because a loose ClickLoc joint causes intermittent signals that look like vibration spikes. When a Proximitor is replaced, the system length digits on the new unit must match the installed probe and cable combination, otherwise the gap reading is offset and the machine must be re-gapped.

Why Seven Star LLC
Seven Star LLC supplies genuine Bently Nevada 3300 XL Proximitors, probes and extension cables to reliability and maintenance programmes across Oman and the GCC. Every Proximitor is verified against its complete part number and configured system length before your order is confirmed, and our team advises on the correct probe and cable combination for your machine.
Technical Specifications
The Bently Nevada 3300 XL Proximitor sensor (330180-X0-05) is a non-contacting eddy-current signal-conditioning module used with a 3300-series 5mm or 3300 XL 8mm proximity probe to output a proportional vibration or position signal. It operates from a -17.5 to -26V DC supply, drawing 12mA or less, with an output impedance of 50Ω and supply sensitivity below 2mV/V. The linear measurement range is 2mm (80 mils), beginning approximately 0.25mm from the target, with a recommended radial gap of about 1.27mm (50 mils) and a scale factor of 7.87V/mm (200mV/mil) ±5%.
System cable lengths are available in 1m, 5m, or 9m configurations to match the probe and extension cable length required for the installation. Operating temperature is rated -52°C to +100°C for the Proximitor itself (storage to +105°C), while the connected probe is rated -52°C to +177°C standard (extended-temperature-range variants to +218°C), and the extension cable -52°C to +177°C standard (ETR variants to +260°C). The housing is A308 aluminum with gold-plated brass or beryllium-copper connectors for reliable long-term signal integrity in harsh environments.
Certifications and Applications
The 3300 XL Proximitor system carries FCC and EMC compliance (EN 61000-6-2/4), RoHS, ATEX/IECEx hazardous-area certification, SIL 2/3 functional-safety capability, and maritime approval depending on the suffix ordered. It is used for radial vibration, axial position/thrust, and Keyphasor speed measurement on turbomachinery, compressors, and pumps — forming the signal-conditioning link between the physical proximity probe and the monitoring rack (typically a Bently Nevada 3300/3500 series system) that performs alarm and trip logic.
