More Information

Overview Manuals DIN Integration System Matching Output Behavior Environmental Limits

Features:

  • The 51 code combines five-metre calibration with a DIN-rail mounting base.
  • The calibrated input preserves the defined electrical relationship across the complete probe chain.
  • SpringLoc terminals provide the monitor-side field connection.
The Proximitor is the signal-conditioning element, not the complete probe, cable and sensor assembly.

Its five-metre calibration defines the combined electrical length allowed between the target-facing probe and sensor input.

No certification package is appended to this part number; the 00 code leaves its DIN mounting choice unchanged.

The Bently Nevada 330780-51-00 3300 XL 11 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 330780-51-00 3300 XL 11 mm Proximitor Sensor Manuals,Datasheets,LinkImportant Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Compact Sensor Placement

  • Mounting base: Code 51 supplies the Proximitor for high-density DIN-rail installation.
  • Terminal method: SpringLoc connections grip field conductors without screw-type clamps.
  • Conductor range: Field terminals accept 0.2 to 1.5 mm² wire.
  • Enclosure material: The signal-conditioning electronics are housed in A380 aluminum.

Five-Metre Chain Rules

  • Input path: The probe signal reaches the sensor through the matched 3300 XL 11 mm cable assembly.
  • Total length: Probe and extension cable must combine to 5.0 m for this calibration.
  • Target standard: Factory calibration uses AISI 4140 steel unless another target material is specified.
  • Mixing boundary: A nine-metre probe chain requires the corresponding 9 m Proximitor code.

Gap-to-Voltage Conversion

  • Working span: The standard linear region extends approximately from 0.5 to 4.5 mm.
  • Centre setting: A 2.5 mm initial gap places normal movement near the middle of the range.
  • Scale relationship: Target movement changes output by 3.94 V/mm within the specified tolerance.
  • Monitor interface: A 50 Ω output drives the field wiring toward the connected monitoring channel.

Installed Operating Boundary

  • Sensor temperature: The Proximitor operates from -52 to +100°C.
  • Humidity: Protected connectors permit 100% condensing humidity, but the unit is not submersible.
  • Radio immunity: Improved RFI/EMI resistance supports dense non-metallic or DIN-rail installations.
  • Field reach: Frequency response remains specified with up to 305 m of field wiring.
Description
Signal conditioning for the five-metre 3300 XL 11 mm chain takes place in Bently Nevada 330780-51-00. This DIN-mounted Proximitor Sensor energizes the non-contact probe circuit and turns the changing electrical response at its input into a low-impedance voltage for the connected monitoring channel.

The 51 ordering code fixes Bently Nevada 330780-51-00 to a 5.0 m total system length and DIN-rail mounting. Probe length plus extension-cable length must equal that calibration length; selecting a nine-metre chain changes the electrical relationship and requires the corresponding Proximitor configuration.

A 4.0 mm linear range allows Bently Nevada 330780-51-00 to follow larger position changes than an 8 mm proximity system. The normal 2.5 mm gap sits near the centre of that range, while the 3.94 V/mm scale factor converts movement of the conductive target into a predictable voltage change for vibration, position or phase-reference processing.

Power and the conditioned output leave Bently Nevada 330780-51-00 through the field terminal side of the sensor. Operation from -17.5 to -26 Vdc without barriers, wiring runs up to 305 m and improved RFI/EMI immunity define how the A380 aluminum unit connects into a dense machinery-monitoring cabinet.

Technical notes
Bently Nevada 330780-51-00 is calibrated for one 5.0 m 3300 XL 11 mm probe-and-cable chain and mounts on DIN rail. Matching the total electrical length preserves its 4.0 mm linear output range.

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 does the 51 code require when assembling Bently Nevada 330780-51-00?
The 51 code makes Bently Nevada 330780-51-00 a DIN-mounted sensor calibrated for a 5.0 m total chain, so probe length plus extension-cable length must equal five metres.
Why can Bently Nevada 330780-51-00 lose part of its linear range even though power is present?
A supply more positive than -23.5 Vdc can reduce the linear range of Bently Nevada 330780-51-00; verify -17.5 to -26 Vdc without barriers or -23 to -26 Vdc with barriers.
Which target condition should be confirmed before scaling Bently Nevada 330780-51-00?
Bently Nevada 330780-51-00 is factory calibrated with an AISI 4140 steel target, so a different alloy requires a separately defined calibration rather than assuming the standard 3.94 V/mm factor.
Which conductor and distance limits apply between Bently Nevada 330780-51-00 and the monitor?
Use three-conductor shielded cable within the 0.2 to 1.5 mm² terminal range for Bently Nevada 330780-51-00, and keep the Proximitor-to-monitor run within 305 m.
Can Bently Nevada 330780-51-00 be substituted alone for a legacy 7200 transducer chain?
No direct component-only substitution should be assumed: Bently Nevada 330780-51-00 belongs to an 11 mm 3300 XL chain, and a 7200 conversion requires the matching probe, extension cable, sensor and monitor setup.
What installation detail protects Bently Nevada 330780-51-00 in condensing humidity?
Bently Nevada 330780-51-00 supports 100% condensing humidity only when its connectors are protected; the Proximitor is not rated for submersion.
