System Architecture & Signal Flow
The 31000-16-05-15-040-02-02 operates as the sensing element in a three-component Bently Nevada proximity system:
- Probe (this assembly) — generates eddy-current field; outputs raw voltage proportional to gap distance
- Extension Cable — transmits signal from probe tip to proximitor/driver (matched impedance required)
- Proximitor / Signal Conditioner (e.g., 3300 XL 8mm Proximitor) — conditions output; feeds 3500 or 3300 monitor rack
System must use matched probe + extension cable + proximitor from the same series for calibrated accuracy.
Sourcing & Quality Verification
- Source: OEM-grade components from authorized distribution and verified surplus inventory
- Inspection: Visual inspection, connector integrity check, and cable continuity test prior to shipment
- Documentation: Certificate of conformance and packing list with every order
- Traceability: Lot and date code records maintained; available upon request
- Packaging: Anti-static foam-lined box with moisture barrier; cable coiled to manufacturer specification
Procurement Process
- Confirm part number 31000-16-05-15-040-02-02 against your BOM or existing probe label

Technical FAQ
Q: Is this probe compatible with the Bently Nevada 3500 monitor rack?
A: Yes. When paired with the correct 3300 XL Proximitor and matched extension cable, output is fully compatible with 3500 Series monitor input cards.
Q: Can I use a different extension cable length?
A: No. Probe, extension cable, and proximitor must be a matched set of the same series and total cable length to maintain calibration.
Q: What is the target material for the eddy-current field?
A: Calibrated for AISI 4140 steel. For other shaft materials (stainless, titanium, Inconel), a material correction factor must be applied per Bently Nevada application note.
Q: Do you provide installation and commissioning support?
A: Konmask.com provides technical documentation and pre-sales engineering consultation via email. On-site commissioning can be arranged through our partner network.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks. Contact us for real-time availability.
