- ATEX / IECEx Certified – Approved for Zone 1 and Zone 2 hazardous area installations
System Architecture & Signal Flow
The 330103-08-19-05-02-00 operates as a three-component eddy current system:
- Probe (8mm) – Generates a high-frequency electromagnetic field (1.0 MHz nominal). As the conductive target shaft approaches or recedes, eddy currents alter the field impedance.
- Extension Cable (19mm body) – Transmits the demodulated RF signal from the probe tip to the proximitor with minimal signal loss. Length is tuned to system calibration.
- Proximitor / Driver (3300 XL) – Demodulates the RF carrier, applies temperature compensation, and outputs a DC-coupled voltage proportional to gap distance. Output feeds directly to Bently Nevada 3500 Series monitors or any API 670-compliant monitoring rack.
Signal output: –24 VDC bias, linear range –2 to –18 VDC, sensitivity 7.87 V/mm. Compatible with 3500/40M, 3500/42M, 3500/45, and 3500/46M monitor modules.

Technical FAQ
Q: Is the 330103-08-19-05-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 3300 XL Proximitor output (–24 VDC bias, 7.87 V/mm sensitivity) is fully compatible with all 3500 Series monitor modules including the 3500/40M, 3500/42M, 3500/45, and 3500/46M.
Q: Can this system be used with non-steel target materials?
A: The standard calibration is optimized for AISI 4140 steel. For stainless steel, titanium, or other alloys, a material-specific calibration factor must be applied. Contact us for recalibrated system options.
Q: What is the difference between the 330103 and 330180 series?
A: The 330103 uses a standard 8mm probe with MIL-C-5015 connectors. The 330180 is a high-temperature variant rated to +177°C for extreme-environment applications such as hot gas expanders.
Q: Is a Certificate of Conformance (CoC) available?
A: Yes. CoC is provided as standard with every shipment. ATEX/IECEx certificates and factory calibration data sheets are available upon request.
Q: Can I order a replacement probe only, without the full system?
A: Yes. Individual probes, extension cables, and proximitors are available separately. Contact support for matched-set configuration options.
