Selection Guide
Use the following criteria to confirm the correct part number for your application:
- Step 1 — Measurement Type: Confirm radial vibration (displacement) vs. velocity or acceleration. The 330706 series is for displacement (proximity probe input).
- Step 2 — Output Requirement: Verify 4–20 mA output is required. For voltage output, consider 330706-05-46-10-01-xx variants.
- Step 3 — Hazardous Area Classification: Check ATEX/FM/CSA requirements. The -02-00 suffix indicates FM/CSA approved version.
- Step 4 — Probe Compatibility: Confirm existing probe is 3300 XL 8mm series. Mixing probe families requires recalibration.
- Step 5 — Connector Type: Verify field wiring connector matches. Contact Konmask if adapter cables are needed.
- Step 6 — Temperature Range: Standard version rated to +85°C. For higher ambient, specify extended-temp variant.

Replacement & Compatibility FAQ
Q: Can I replace 330706-05-46-10-02-00 with a third-party transmitter?
A: Yes, functionally equivalent third-party units (e.g., Metrix ST5484E) can be used in non-API-critical applications. For API 670 systems, OEM replacement is strongly recommended.
Q: Is this transmitter compatible with the Bently Nevada 3500 rack?
A: The 330706 series is natively designed for the 3300 rack. Use with 3500 requires an interface adapter — contact Konmask for details.
Q: What is the difference between the -02-00 and -01-00 suffix?
A: The last two digits indicate the connector/wiring configuration. -02-00 is the FM/CSA hazardous area approved variant; -01-00 is the standard industrial version.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration documentation is available for all OEM units. Request at time of order.
Q: Can this unit be repaired if damaged?
A: Bently Nevada transmitters are generally not field-repairable. Replacement is the standard practice. Konmask offers exchange programs for cost savings.
