Bently Nevada 21505-00-40-10-02 Proximity Probe – 3300 Series Eddy Current Sensor System
When a critical rotating machine — a steam turbine, compressor, or pump — loses its vibration monitoring capability, the consequences are immediate and severe. Without a functioning proximity probe, operators are blind to shaft displacement, orbital motion, and the early warning signs of bearing failure or rotor instability. Unplanned shutdowns, catastrophic mechanical damage, and costly production losses follow. The Bently Nevada 21505-00-40-10-02 proximity probe is the precision sensing element that keeps your machinery protection system fully operational and your plant running safely.
The 21505-00-40-10-02 is a core component of the Bently Nevada 3300 Series eddy current transducer system — one of the most widely deployed machinery monitoring platforms in global industrial automation. Engineered to API 670 standards, this probe delivers sub-micron resolution shaft position measurement and is trusted in power generation, oil & gas, petrochemical, and heavy manufacturing facilities across more than 100 countries. Its 8 mm tip diameter and 40 mm cable configuration make it the preferred choice for tight-clearance installations where measurement accuracy is non-negotiable.

Frequently Asked Questions
- Q: Is the 21505-00-40-10-02 a direct replacement for other 3300 Series 8mm probes?
- A: Yes, within the 3300 Series 8mm probe family, the 21505-00-40-10-02 is dimensionally and electrically compatible with other 8mm probes in the series, provided the extension cable and Proximitor® driver are also 3300 Series components. Always verify the complete system configuration before installation.
- Q: Can this probe be used with non-Bently Nevada monitors?
- A: The probe outputs a standard eddy current signal (nominally -18V DC bias, 200 mV/mil sensitivity) that is compatible with many third-party monitors designed for 3300 Series inputs. Consult your monitor manufacturer’s specifications to confirm compatibility.
- Q: What is the lead time for the 21505-00-40-10-02?
- A: Lead time varies by stock availability. Contact Konmask.com for a real-time availability check and delivery estimate. We maintain relationships with multiple sourcing channels to minimize lead times.
- Q: Do you provide a warranty on this product?
- A: Yes. We offer a standard warranty covering manufacturing defects. Warranty terms are specified in the quotation. Our quality inspection process minimizes the risk of receiving a defective unit.
- Q: Can you supply the complete 3300 Series system (probe + cable + Proximitor®)?
- A: Absolutely. Konmask.com can source and supply the complete measurement chain. Please provide your system requirements and we will prepare a comprehensive quotation.
