Engineering Advantages
- Non-contact measurement eliminates mechanical wear and enables continuous 24/7 operation without maintenance intervals
- High-frequency response (DC–10 kHz) captures both low-speed runout and high-frequency sub-synchronous instabilities
- 200 mV/mil scale factor provides excellent signal resolution for early fault detection and trend analysis
- Wide temperature range (–35°C to +177°C) ensures reliable operation in both cryogenic and high-temperature process environments
- Integral cable design eliminates field-assembly connector errors and reduces installation time
- Full API 670 compliance satisfies machinery protection specifications for critical and essential machinery classifications
- Backward compatibility with 3300 Series proximitors protects existing infrastructure investment
System Architecture & Signal Flow
The 330101-00-20-0-5-02-05 operates as the sensing element within a three-component Bently Nevada proximity transducer system:
- Probe (330101-00-20-0-5-02-05): Generates a high-frequency electromagnetic field (1.0 MHz nominal). Eddy currents induced in the conductive target shaft attenuate the field proportionally to gap distance.
- Extension Cable (330130 Series): Transmits the demodulated signal from probe to proximitor with defined system impedance. Total cable length (probe + extension) must match proximitor calibration.
- Proximitor/Monitor (3300 XL Series): Demodulates the oscillator signal, applies scale factor calibration, and outputs a DC voltage proportional to gap. Interfaces with DCS, PLC, or dedicated machinery protection monitors (e.g., 3500 Series rack).
Note: System calibration is performed as a matched set. Always verify total system cable length against proximitor calibration curve before installation.

Technical FAQ
Q: Is the 330101-00-20-0-5-02-05 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. When paired with a compatible 3300 XL proximitor and appropriate extension cable, the output signal is fully compatible with 3500 Series monitor inputs.
Q: Can this probe be used with non-steel target materials?
A: The standard calibration is optimized for AISI 4140 steel. For other target materials (stainless steel, titanium, aluminum), a material correction factor must be applied. Contact Bently Nevada or Konmask engineering for target-specific calibration data.
Q: What is the maximum shaft speed this sensor can monitor?
A: The DC–10 kHz frequency response supports shaft speeds up to approximately 600,000 RPM for 1× vibration detection, making it suitable for virtually all industrial rotating machinery applications.
Q: How do I verify the total system cable length for my installation?
A: Total system length = probe integral cable (2.0 m) + extension cable length. This total must match the proximitor’s calibrated cable length (typically 5 m, 9 m, or 15 m systems). Mismatched lengths will introduce scale factor error.
Q: Is a Certificate of Conformance (CoC) available?
A: Yes, CoC documentation is available upon request. Please specify your requirement at the time of order or contact support@konmask.com.
