System Architecture & Signal Flow
The PROXPAC XL operates on the eddy-current principle. The probe tip generates a high-frequency electromagnetic field (typically 1 MHz). When a conductive target enters the field, eddy currents are induced, loading the oscillator circuit. The proximitor electronics convert this impedance change into a linear DC voltage output proportional to the gap between probe tip and target surface. The signal is then routed to a Bently Nevada 3300 Series monitor card (e.g., 3300/16, 3300/20) for alarm processing, trending, and System 1 data acquisition.
Signal path: Probe tip → Extension cable (5 m) → Proximitor oscillator/demodulator → –2 to –18 VDC output → Monitor input card → System 1 / DCS/PLC integration.

Technical FAQ
- Q: Is 330880-16-00-060-03-02 compatible with the 3300/16 monitor?
- A: Yes. The PROXPAC XL 330880 series is designed for direct connection to all Bently Nevada 3300 Series monitor cards including the 3300/16, 3300/20, and 3300/25.
- Q: Can this transducer be used with non-steel targets?
- A: The standard calibration is for AISI 4140 steel. For other alloys (Inconel, titanium, aluminum), a target material correction factor must be applied. Contact our engineering team for recalibration options.
- Q: What is the difference between PROXPAC and PROXPAC XL?
- A: PROXPAC XL features an extended linear range and improved high-temperature performance compared to the standard PROXPAC, making it suitable for more demanding turbomachinery applications.
- Q: Do you provide a warranty?
- A: Yes. Konmask.com provides a 12-month warranty against manufacturing defects on all new units. Refurbished units carry a 6-month warranty.
- Q: Can I get a datasheet or calibration certificate?
- A: Yes. Email [email protected] with your order number or inquiry reference and we will provide the relevant documentation within 24 hours.
