SYSTEM INTEGRATION MAP
A large-range proximity system is purchased as a measurement chain—not as an isolated sensor box.
51 defines a 5.0 m system with DIN-rail mounting. 00 indicates no agency approval option. The 35 mm rail is not included with the sensor.
The probe and extension cable part numbers must be chosen so their combined electrical length is 5 m.
The extended linear range supports large steam-turbine applications such as differential expansion and rotor expansion where standard 8 mm systems do not provide enough range.
Supply −17.5 to −26 Vdc; maximum current 12 mA; output impedance 50 Ω; nominal scale factor 394 mV/mm (10 mV/mil).
Request a quote with the 330876 probe code, 330877 cable code, turbine measurement point, rail mounting and quantity.
Submit the 5 m chainOfficial technical reference: Baker Hughes / Bently Nevada 3300 XL 50 mm datasheet. Stockoems is an independent supplier.
A customer searching for a Bently Nevada 330878-51-00 Proximitor Sensor is usually maintaining a large-range expansion measurement. The sensor must be assessed with its 330876 probe and 330877 extension cable. The combined system length for suffix 51 is 5 m, and the DIN-rail mounting configuration must fit the installed cabinet.
For a reliable 3300 XL 50 mm proximity system quotation, submit the entire ordering chain. A price for the Proximitor alone does not confirm range, length, mechanical installation or monitor compatibility.
| Evidence | Why the buyer needs it |
|---|---|
| 330876 probe label | Confirms probe configuration and cable contribution. |
| 330877 extension-cable label | Confirms extension length and ordering option. |
| 330878-51-00 label | Confirms 5 m DIN-mount sensor, no approval suffix. |
| Monitor configuration | Confirms scaling, alarm logic and measurement direction for commissioning. |
Preserve the mechanical reference and verify gap/position using the approved site procedure. A large-range system used for turbine expansion can influence protection decisions; replacement, scaling and functional checks should be performed by qualified site personnel.
Do not automatically substitute 5 m and 9 m versions, panel and DIN mounts, or different approval suffixes. These options have distinct ordering and installation consequences.
Attach probe, extension-cable and Proximitor labels plus application, monitor channel, quantity, destination and required delivery date.

MATCHED-SYSTEM SHIPMENT CONTROL
Procurement, packing and shipping are coordinated around the complete 330876 + 330877 + 330878 five-metre measurement chain.
The quotation states exact line items, condition, quantity, availability, dispatch estimate, freight basis, quotation validity and requested documents.
T/T bank transfer, Alipay or other agreed methods are confirmed on the quotation/PI. Verify beneficiary information before payment.
Each item remains identifiable; probe tip, connectors, cable and sensor housing receive appropriate protective separation and cushioning.
DHL, FedEx or SF can be selected according to destination and order requirements. Tracking is released after carrier collection.
A 12-month quality-issue warranty is stated by Stockoems, subject to the final written terms. At receipt, compare all three line-item labels with the purchase order and preserve shipment evidence if shortage or damage is identified.
Freight, Incoterm, taxes/duties, dispatch estimate and warranty scope follow the formal quotation or proforma invoice.
Changing 5 m to 9 m changes the matched probe/cable chain. Verify the complete system rather than replacing only the Proximitor Sensor.
PROXIMITY-SYSTEM MODELS FOUND IN THE FILES
These entries match Bently Nevada, but they belong to 25 mm, 8 mm or 3500 monitoring families. They help build a related-parts RFQ; none is a drop-in 50 mm replacement.
