Bently Nevada 330850-90-00 Proximitor Sensor
A panel-mount 3300 XL 25 mm Proximitor Sensor for a 9.0 m system without agency approvals.
Product Identification
330850-90-00 is the panel-mounted signal conditioner for a 9.0 m 3300 XL 25 mm proximity system. Its suffix identifies the standard no-approval execution.
The exact probe and extension-cable lengths must add to 9.0 m. This calibration rule is independent of the sensor mounting style.

- Keep static-output and channel-test results with the point history.
FAQ
How does 330850-90-00 differ from the 330850-91-00 execution?
Both are 9.0 m no-approval sensors, but 90 is panel mount and 91 is DIN mount.
Can 330850-90-00 operate with a 5.0 m transducer loop?
No. Its calibration is for a 9.0 m combination of probe and extension cable.
Is 330850-90-00 suitable for a certified hazardous-area installation?
The final 00 means no agency approvals; use the project certification requirements to choose the correct execution.
What prevents a wrong 330850-90-00 replacement?
Check mounting, total system length, approval suffix, probe family, wiring and monitor scaling before ordering.
What should be tested after fitting 330850-90-00?
Prove the complete loop, including static gap voltage, dynamic response, alarms and channel integrity.
What information should accompany a 330850-90-00 enquiry?
Provide all three transducer component numbers, cabinet mounting photographs, monitor model and site approval requirement.
