Bently Nevada 330101-00-11-20-02-05 8 mm Proximity Probe
Product Overview
The Bently Nevada 330101-00-11-20-02-05 is an 8 mm non-contacting eddy-current proximity probe engineered for use with the 3300 XL series of machinery protection systems. Designed for precision monitoring of shaft position and vibration, this probe delivers repeatable, high-resolution measurements in harsh industrial environments.
Equipped with a stainless-steel probe tip and integrated spring assembly, the unit ensures stable air-gap maintenance and resistance to mechanical shock. Its PTFE-insulated, shielded coaxial cable conveys a clean ±10 V signal proportional to shaft displacement, supporting advanced diagnostics and predictive maintenance.

Frequently Asked Questions (FAQ)
Q1: What sensing principle does this probe use?
A1: It employs eddy-current induction to convert shaft gap into an AC voltage signal.
Q2: Can the cable length be customized?
A2: Yes, variants are available in 2 m, 3 m, 6 m, and longer upon request.
Q3: How is the probe connected?
A3: Via a standard 10-pin MIL-C-26482 stainless-steel connector to the 3300 XL monitor card.
Q4: What is the optimal sensing gap?
A4: Recommended gap is 0.25–1.0 mm for best linearity and sensitivity.
Q5: Does it need periodic calibration?
A5: Calibration is typically set at installation; re-calibration intervals depend on usage and operating conditions.
Q6: How does it handle electromagnetic interference?
A6: Shielded PTFE cable and grounding spring assembly provide robust EMI protection.
Q7: What environmental standards does it meet?
A7: Rated –40 °C to +120 °C, 100 g shock, and complies with IEC EMC requirements.
Q8: Can it tolerate occasional contact with the shaft?
A8: It can withstand light rubs at low speed but should not be forced into heavy contact.
Q9: How is linearity specified?
A9: Linearity is better than 1 % of full scale within the recommended gap range.
Q10: Where can I obtain technical documentation?
A10: Full datasheets and installation guides are available through Bently Nevada’s official support channels.
