System Architecture & Signal Flow
The 330103-05-10-05-02-00 operates as a three-component eddy current system:
- Probe (330103): Generates a high-frequency electromagnetic field (1.0 MHz nominal). When a conductive target (shaft) enters the field, eddy currents are induced, altering the probe’s impedance.
- Extension Cable: Transmits the impedance-modulated signal from the probe to the proximitor driver with minimal signal degradation. Cable length is matched and calibrated as part of the system.
- Proximitor/Oscillator Driver: Demodulates the impedance change into a DC voltage output proportional to the gap distance. Output feeds directly into Bently Nevada monitor input cards (e.g., 3500/42M, 3500/45).
Note: All three components (probe + extension cable + driver) are factory-matched and must be used as a complete system to maintain calibration accuracy.

Technical FAQ
Q: Can the 330103-05-10-05-02-00 be used with non-Bently Nevada monitors?
A: The output is a standard -24V-powered DC voltage signal (–2 to –18 VDC). It can interface with third-party monitors that accept this signal range, but calibration and API 670 compliance must be verified by the end user.
Q: What is the difference between the 330103 and 330104 probe series?
A: The 330103 is designed for standard steel targets (AISI 4140). The 330104 is optimized for non-standard target materials. Always confirm target material before specifying probe type.
Q: Is the extension cable length fixed?
A: Yes. The probe, extension cable, and driver are a matched, calibrated system. Substituting cable lengths will alter the scale factor and void calibration. Contact us if you require a different cable length configuration.
Q: Do you provide installation and commissioning support?
A: We provide technical documentation and remote guidance. For on-site commissioning, we recommend engaging a certified Bently Nevada service partner.
