System Architecture & Signal Flow
The 31000-16-10-15-063-03-02 housing assembly integrates within the standard Bently Nevada 3300 XL signal chain:
- Probe (31000 series) → eddy-current field generation at shaft surface
- Extension Cable (3300 XL) → signal transmission from probe to Proximitor® sensor
- Proximitor® Sensor (3300 XL) → signal conditioning, -24 VDC supply, voltage output
- Monitor (3500/22M or equivalent) → alarm, trip, and data acquisition
- DCS / Safety System → 4–20 mA or relay output integration
The housing assembly provides the critical mechanical mounting and environmental sealing interface between the probe tip and the machinery casing, ensuring consistent gap setting and long-term measurement stability.

Technical FAQ
Q: Is this a genuine Bently Nevada OEM part?
A: This is an OEM-equivalent or verified surplus part. Konmask.com sources from traceable supply chains. Contact us for CoC documentation.
Q: Can this probe be used with non-Bently Nevada Proximitor® sensors?
A: The 31000 series is optimized for Bently Nevada 3300 XL Proximitor® sensors. Cross-brand compatibility requires independent calibration verification.
Q: What is the recommended installation gap?
A: Nominal installation gap is 1.0 mm (40 mil), corresponding to the mid-point of the linear range (-12 VDC output). Refer to Bently Nevada installation manual 141536-01 for detailed procedures.
Q: Is expedited shipping available?
A: Yes. Express air freight (DHL Express / FedEx Priority) is available for urgent requirements. Contact us for lead time confirmation.
Q: Do you provide volume pricing for MRO or project procurement?
