Bently Nevada 330910-14-19-10-02-00 – High-Precision Eddy Current Proximity Probe | NSv Series Platform
Engineering Background
The Bently Nevada NSv (Non-contacting vibration) Series represents the industry benchmark for shaft vibration and axial position measurement in rotating machinery. Developed by Baker Hughes (Bently Nevada), the NSv platform is engineered to meet the stringent demands of continuous online monitoring in power generation, oil & gas, petrochemical, and heavy industrial environments. The 330910 series proximity probes are the sensing element of a complete eddy current measurement chain, working in conjunction with extension cables and signal conditioners (proximitors) to deliver calibrated, real-time displacement data.
Product Positioning
The 330910-14-19-10-02-00 is a 14 mm diameter, 19 mm gap range, 10 mm cable length configuration NSv proximity probe. It is purpose-built for OEM turbomachinery installations and retrofit upgrades where dimensional compatibility, signal accuracy, and long-term reliability are non-negotiable. Konmask.com supplies this part as a verified OEM-equivalent component, fully traceable and ready for immediate deployment in critical monitoring systems.

System Architecture & Signal Flow
The 330910-14-19-10-02-00 probe operates as the primary sensing element in a three-component eddy current measurement chain:
- Proximity Probe (330910-14-19-10-02-00): Generates a high-frequency electromagnetic field at the probe tip. Eddy currents induced in the rotating target shaft modulate the field, producing a gap-proportional voltage signal.
- Extension Cable (330130 series): Transmits the raw oscillator signal from the probe to the proximitor with minimal loss. Total system cable length (probe + extension) must match the proximitor calibration.
- Proximitor / Signal Conditioner (3300 XL or equivalent): Demodulates the oscillator signal, applies scale factor calibration, and outputs a DC voltage proportional to shaft gap for connection to the monitoring system (e.g., Bently Nevada 3500 rack, DCS analog input card).

Technical FAQ
Q: Is the 330910-14-19-10-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. When paired with the correct 3300 XL proximitor and matching extension cable, this probe is fully compatible with the 3500 series rack and all standard Bently Nevada monitoring platforms.
Q: Can this probe be used with a non-Bently Nevada signal conditioner?
A: Technically possible if the third-party conditioner is calibrated to the 7.87 V/mm (200 mV/mil) scale factor and the correct oscillator frequency. Consult your instrumentation engineer before substitution in safety-critical applications.
Q: What is the recommended installation gap for this probe?
A: The nominal installation gap is typically set at the midpoint of the linear range — approximately 1.0 mm (40 mil) for a 19 mm range probe. Refer to the Bently Nevada installation manual for your specific machine configuration.
Q: Do you offer expedited shipping for plant shutdowns?
A: Yes. Contact us directly at +0086 19859288691 or support@konmask.com for emergency procurement support. DHL Express next-flight-out options are available.
Q: Is a calibration certificate included?
A: A certificate of conformance is included as standard. NIST-traceable calibration certificates can be arranged upon request for an additional lead time of 3–5 business days.
