Bently Nevada 144181-51-05 3300 XL Proximitor Sensor

144181-51-05 is a legacy Bently Nevada reference for a 3300 XL Proximitor Sensor that supplies and conditions a compatible eddy-current probe system. Its 5.0 m DIN-mounted configuration produces a 200 mV/mil signal for a compatible machinery-protection or condition-monitoring channel.

144181-51-05 uses a legacy base reference, while current Baker Hughes ordering data lists the equivalent 5.0 m DIN-mounted, multiple-approval configuration under the 330180 family. Replacement must be based on the complete nameplate, connector and approval markings rather than the shared suffixes alone.

144181-51-05 must be used with a compatible Bently Nevada 5 mm or 8 mm probe and extension cable whose combined electrical length equals 5.0 m. A different total length changes the calibrated system and is not a valid direct substitution.

144181-51-05 is identified as a DIN-mounted configuration, so a panel-mount version is not a mechanical drop-in replacement. The mounting method, wiring terminals, monitor input and enclosure clearances must all be confirmed before changing versions.

144181-51-05 carries the -05 multiple-approval configuration associated with CSA, ATEX and IECEx markings in the current family data. The installed hazardous-area classification, barrier arrangement and exact label markings still have to be checked for the destination site.

144181-51-05 requires a compatible -24 V DC supply, normally within -17.5 to -26 V DC without barriers, and a monitor channel designed for the 200 mV/mil output. Probe polarity, common wiring, cable shield routing and any safety barrier must match the existing system.

144181-51-05 should be quoted with the complete nameplate reference, clear label and terminal photos, quantity, destination, installed probe and extension-cable numbers, total system length, monitor model, mounting style and hazardous-area requirement. These details allow the legacy reference and compatible replacement to be verified.
