Bently Nevada 21000-16-10-15-105-03-02 Proximity Probe Housing Assembly | Replacement, Equivalent & Selection Guide
When a proximity probe housing fails on a critical rotating machine — a gas turbine, centrifugal compressor, or high-speed pump — the entire vibration monitoring chain goes blind. Without an accurate, calibrated housing assembly, your Bently Nevada 3300 XL Proximitor® sensor cannot deliver reliable shaft position or radial vibration data, leaving your machinery protection system unable to detect dangerous conditions before they escalate to catastrophic failure. The Bently Nevada 21000-16-10-15-105-03-02 Proximity Probe Housing Assembly is the precision-engineered component that keeps your monitoring system fully operational.
Within the 3300 XL Proximity Transducer System, the 21000-16-10-15-105-03-02 occupies the 16 mm tip-diameter tier — the largest standard probe size in the series — delivering the widest linear measurement range and highest signal stability for large-shaft, high-vibration applications. Globally, the 3300 XL platform is the de facto standard for turbomachinery protection in oil & gas, power generation, and petrochemical industries, making genuine OEM replacement parts a critical procurement priority for plant reliability teams worldwide.

Selection Guide
Use the following five-step process to confirm the correct part number for your application:
- Step 1 – Probe Tip Diameter: Match to your existing probe bore — 8 mm, 11 mm, 14 mm, or 16 mm
- Step 2 – Cable Length: Measure the distance from probe tip to Proximitor® sensor. Common lengths: 0.5 m, 1.0 m, 1.5 m, 5.0 m, 9.0 m
- Step 3 – Thread Specification: Confirm M10 × 1 or alternate thread from your housing drawing
- Step 4 – Connector Type: Verify suffix -03 (standard) or alternate connector code from your existing assembly label
- Step 5 – Certification Requirement: Confirm ATEX Zone, FM Division, or non-hazardous area classification for your installation

Replacement & Compatibility FAQ
Q: Can I replace 21000-16-10-15-105-03-02 with a different cable length variant?
A: Yes, provided the total system cable length (probe + extension) matches the Proximitor® sensor’s specified range. Contact us to verify your system’s total cable length budget.
Q: Is an 8 mm probe housing interchangeable with a 16 mm unit?
A: No. Probe tip diameter determines the gap voltage curve and must match the Proximitor® sensor calibration. Mixing diameters will produce inaccurate measurements and may trigger false trips.
Q: Can I use a third-party equivalent instead of the genuine Bently Nevada part?
A: Third-party equivalents may fit mechanically but can void ATEX/FM certifications and System 1® compatibility. We strongly recommend genuine OEM parts for safety-critical applications.
Q: How do I decode the Bently Nevada 21000 part number?
A: The format is: 21000-[Diameter mm]-[Thread]-[Cable Length ×10 cm]-[Sensitivity code]-[Connector]-[Housing]. Our team can decode any 21000-series part number — just send us the label photo.
Q: What is the lead time for this part?
A: In-stock units ship within 3–7 business days. For out-of-stock or urgent requirements, contact us for expedited sourcing options.
Q: Does Konmask.com provide a certificate of conformance?
A: Yes. Certificates of conformance and traceability documentation are available upon request for all OEM units.
