System Architecture & Signal Flow
The 330904-00-11-05-02-00 operates as the sensing element in a three-component eddy current measurement chain:
- Probe (330904-00-11-05-02-00) → generates high-frequency electromagnetic field at tip
- Extension Cable (3300 XL series) → transmits RF signal with matched impedance
- Proximitor® Driver (3300 XL 8mm/11mm) → demodulates signal, outputs –24 VDC proportional voltage
- Monitor (3500/3300 series) → processes voltage, applies alarm/trip logic per API 670
This architecture ensures the probe’s 7.87 V/mm sensitivity is preserved end-to-end, with system accuracy typically within ±1% of full-scale range.
Sourcing & Quality Verification
Every Bently Nevada probe shipped from Konmask.com undergoes a documented 4-step verification process:

Technical FAQ
Q: Is the 330904-00-11-05-02-00 interchangeable with the 330904-00-16-05-02-00?
A: No. The -11- designation indicates an 11mm tip diameter; the -16- variant is a 16mm probe. They use different Proximitor® drivers and are not interchangeable without recalibration of the entire measurement chain.
Q: Can this probe be used with non-Bently Nevada monitors?
A: The probe outputs a standard –24 VDC eddy current signal. It can interface with third-party monitors that accept this signal format, but sensitivity calibration must be verified independently.
Q: What is the shelf life of an unused probe?
A: Bently Nevada specifies a 10-year shelf life for properly stored probes (dry, room temperature, original packaging). We ship only units within active shelf life.
Q: Do you provide calibration certificates?
A: Factory calibration data is available for new units. For recertification, we recommend Bently Nevada’s authorized service centers. Contact us for details.
Q: What is your minimum order quantity?
A: MOQ is 1 unit. Volume pricing is available for orders of 5+ units.
