More Information

Overview Manuals Ordering Code Measurement Boundary System Matching Product Applications

Features:

  • 25 mm system: Provides a wide 12.7 mm linear range for large proximity measurements.
  • DIN-mounted configuration: Ordering code 91 specifies a 9.0 m system length and DIN mounting.
  • Interference control: The Proximitor design improves immunity to radio-frequency and electromagnetic interference.
330850-91-00 is the signal-conditioning element for a matching Bently Nevada 3300 XL 25 mm proximity transducer system.

Its order code fixes the total system length, mounting method, and approval selection.

Accuracy depends on the complete probe, extension cable, Proximitor, target material, target size, gap, and monitor scaling.

Apter Power supports 330850-91-00 enquiries with configuration review, sourcing assistance, technical documentation, and system-matching guidance.

  • Commissioning support: Provides a defined 12.7 mm range for setting and checking the installed probe gap.
  • Legacy maintenance: The complete 330850-91-00 identity separates DIN, panel, system-length, and approval variants.
Description
330850-91-00 is the DIN-mounted Proximitor sensor configuration for the Bently Nevada 3300 XL 25 mm proximity transducer system. Ordering code 91 specifies a 9.0 m system length with DIN mounting, while code 00 selects no agency approvals.

Designed for large-range proximity measurement, 330850-91-00 conditions the probe signal for applications such as differential expansion. The 25 mm system provides a 12.7 mm (500 mil) linear range and improved resistance to radio-frequency and electromagnetic interference.

For the published accuracy and interchangeability, 330850-91-00 should be applied with the matching 25 mm probe and extension-cable configuration against the specified AISI 4140 steel target. Confirm a target diameter of at least 61 mm, the 7.0 mm nominal gap reference, total system length, mounting style, and approval needs before replacement.

Technical notes
The 91 option combines a 9.0 m total system length with DIN mounting, and the 00 option carries no agency approval. Measurement accuracy depends on the complete 25 mm probe, extension cable, Proximitor, target material, target diameter, and gap matching the published system configuration before commissioning.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must match before procuring 330850-91-00 for an existing machine?
Confirm the 25 mm probe family, extension cable, 9.0 m system length, DIN mounting, target material, and monitor scaling.
Why may 330850-91-00 show reduced usable range after installation?
Incorrect supply voltage, target geometry, probe gap, field wiring, or mismatched transducer components can reduce expected performance.
How should target material be handled when commissioning 330850-91-00?
Use the documented AISI 4140 calibration basis or obtain an engineering review for another conductive target material.
What checks help isolate a wiring fault around 330850-91-00?
Verify supply voltage, shielded field wiring, terminal condition, probe and extension-cable continuity, gap voltage, and monitor input.
When is 330850-91-00 appropriate for differential-expansion measurement?
Use it only where the machine design calls for the complete 3300 XL 25 mm system and its 12.7 mm linear range.
What records should be retained after servicing 330850-91-00?
Keep the full code, probe and cable identities, target data, gap, mounting position, output checks, and connected monitor channel.
