System Architecture & Signal Flow
The 330881-16-00-205-00-02 operates as part of a three-component eddy-current measurement chain:
- Transducer (330881): Generates high-frequency electromagnetic field; detects shaft proximity via eddy-current effect. Tip-to-shaft gap produces proportional DC voltage output.
- Extension Cable (330130 / included -205-00 suffix): Low-loss coaxial cable transmits signal from transducer to proximitor/oscillator with minimal attenuation.
- Proximitor / Oscillator (330180 / 3300 XL): Conditions raw transducer signal, provides –24 VDC excitation, and outputs calibrated –VDC signal to monitor card.
- Monitor Card (3300/16 or 3500/42): Processes conditioned signal for vibration amplitude, phase, and gap (DC) measurements; triggers alarms and trips per API 670 setpoints.
Signal path: Shaft → Transducer tip → Extension cable → Proximitor → Monitor card → DCS/Safety system

Technical FAQ
Q: Is the 330881-16-00-205-00-02 compatible with the Bently Nevada 3500 Series monitors?
A: Yes. This transducer is compatible with 3500/42 and 3500/42M monitor cards when used with the appropriate proximitor (330180 or 3300 XL series). Verify scale factor settings in the monitor configuration match the transducer sensitivity of 7.87 V/mm.
Q: What is the difference between the -00-02 and -00-CN connector suffix?
A: The -02 suffix denotes a standard international connector configuration. The -CN suffix is a China-market variant with localized connector termination. Both are electrically identical; connector type affects only physical mating at the proximitor end.
Q: Can this transducer be used on non-steel target materials?
A: The standard calibration is optimized for AISI 4140 steel. For stainless steel, titanium, or other alloys, a material-specific scale factor correction must be applied at the monitor card. Contact Konmask technical support for correction factor tables.
Q: What is the minimum order quantity?
A: MOQ is 1 unit. Volume pricing is available for orders of 5 units or more. Contact support@konmask.com for volume quotation.
Q: How do I verify authenticity of the unit received?
A: Each unit ships with a Konmask inspection certificate. Verify the part number label, date code, and connector markings against Bently Nevada published specifications. Request a copy of our sourcing documentation if required for your quality management system.
