Selection Guide
Use the following parameters to select the correct 330103 variant for your application:
- Probe tip diameter: 8 mm (330103) vs. 11 mm (330104) — choose based on available mounting bore and required linear range
- Extension cable length: Encoded in part number (e.g., -50- = 5.0 m). Total system cable = probe cable + extension cable; must match proximitor input specification
- Target material: Standard calibration for AISI 4140; request special calibration for stainless steel, titanium, or other alloys
- Temperature rating: Confirm probe and driver operating temperature against installation environment
- Certification: CN suffix denotes Chinese market configuration; verify ATEX/IECEx requirements for hazardous area installations
- Sensitivity: 7.87 V/mm standard; confirm with monitor input range for correct scaling

Replacement & Compatibility FAQ
Q: Can I use a 330104 probe with a 330103 proximitor?
A: No. The 330103 (8 mm) and 330104 (11 mm) probes require matched proximitors. Mixing probe and driver sizes will result in incorrect sensitivity and potential system fault.
Q: Is the Epro PR6423 a direct drop-in replacement?
A: Functionally equivalent in most applications, but connector pinout and cable impedance may differ. A wiring adapter and recalibration of the monitor may be required. Contact us for a detailed compatibility report.
Q: What does the CN suffix mean?
A: CN denotes the Chinese market configuration, typically referencing connector type or regional certification markings. Electrically, performance is identical to the standard international variant.
Q: Can this transducer be used with a Bently Nevada 3500 monitor?
A: Yes. The 330103 series is fully compatible with the 3500 Machinery Protection System when used with the appropriate 3500/42M or 3500/40M monitor modules.
Q: Do you provide calibration certificates?
A: Yes. Calibration documentation is available upon request for all units. Please specify your requirement at the time of order.
