Bently Nevada 330850-91-05 Proximitor Sensor
A DIN-rail 3300 XL 25 mm Proximitor Sensor calibrated for a 9.0 m system with multiple approvals.
Technical Summary
330850-91-05 is the signal-conditioning element for a 9.0 m 3300 XL 25 mm proximity transducer system. The 91 option combines the 9.0 m calibration with DIN mounting, while the 05 suffix identifies the multiple-approval execution.
Correct operation depends on the matching 25 mm probe and extension cable. Mechanical fit alone is not evidence that another sensor family or system length is interchangeable.

- Uses DIN mounting for organized cabinet installation and service access.
- Carries the multiple-approval execution identified by the final 05 code.
- Maintains the calibration relationship for the complete 9.0 m transducer chain.
Compatibility
- Pair only with the specified 3300 XL 25 mm probe and extension cable lengths totaling 9.0 m.
- Verify DIN-rail space, terminal wiring, power and monitor-channel scaling.
- Keep the approval selection aligned with the site certification record.
Replacement
- Record terminal wiring, sensor orientation and the complete probe/cable part numbers.
- Inspect connectors and extension cable before attributing a channel fault to the sensor.
- After exchange, verify static output, alarm scaling and the complete channel response.
FAQ
Can 330850-91-05 be used with a 5.0 m probe-and-cable combination?
No. This sensor is the 9.0 m execution; the probe and extension cable together must match that system length.
How does 330850-91-05 mount in the cabinet?
The 91 option is the 9.0 m DIN-mount execution, so confirm rail space and terminal access.
What does the final 05 mean in 330850-91-05?
It identifies the multiple-approval version; the required certification should be checked against the site documents.
Can a panel-mount sensor replace 330850-91-05?
Only after the mounting, wiring, approvals and complete system configuration are reviewed; the submitted model is DIN mount.
What information should accompany a 330850-91-05 request?
Provide the probe, extension cable and sensor numbers, monitor-channel details, cabinet photographs and area-classification requirement.
What should be tested after replacing 330850-91-05?
Confirm loop length, static gap voltage, signal response, monitor scaling, alarms and channel integrity under the approved procedure.
