Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional equivalents or drop-in replacements for the ENTEK 6682 / C6682. Compatibility depends on system configuration, probe type, and rack architecture.
- Bently Nevada 3300/16 – Industry-standard axial position monitor; API 670 compliant; widely used in turbomachinery protection systems
- Bently Nevada 3500/42M – Enhanced position monitor with Modbus/PROFIBUS communication; suitable for modern DCS integration
- Emerson CSI 6500 ATG – Advanced machinery protection with integrated diagnostics; suitable for critical compressor and turbine trains
- Metrix MX2033 – Cost-effective axial position monitor; compatible with standard eddy-current probe systems
- ENTEK IRD 6682 – Direct predecessor/variant; same form factor, verify firmware compatibility
- Rockwell Automation 1440-AXL02-01RB – Allen-Bradley equivalent for integrated PlantPAx environments

Why Choose the Original Model
- Proven field reliability in petrochemical, power generation, and heavy industry environments
- API 670 compliance ensures compatibility with international machinery protection standards
- Direct rack compatibility with existing ENTEK monitoring chassis — no rewiring required
- Established spare-parts ecosystem with documented calibration procedures
- Lower integration risk compared to cross-brand substitutions in safety-critical applications
Typical Applications
- Steam and gas turbine axial thrust monitoring
- Centrifugal compressor protection systems
- Pump and motor shaft displacement measurement
- Petrochemical plant rotating equipment health monitoring
- Power generation machinery protection panels
- Offshore platform critical machinery surveillance
System Compatibility
The ENTEK 6682 / C6682 is designed to integrate with:
- ENTEK Emonitor / Odyssey machinery protection racks
- Standard eddy-current proximity probe systems (e.g., 5 mm, 8 mm probe drivers)
- DCS platforms via 4–20 mA analog output (Honeywell, ABB, Yokogawa, Emerson DeltaV)
- SCADA systems with relay-contact integration
- API 670-compliant machinery protection panels
Selection Guide
Use the following criteria to determine whether the ENTEK 6682 / C6682 or an equivalent model is the right choice for your application:
- Existing rack system: If your plant uses an ENTEK monitoring rack, the 6682 is the lowest-risk direct replacement.
- Probe compatibility: Confirm probe driver gap voltage and sensitivity (V/mm) match the monitor’s input specification.
- Communication requirements: If Modbus, PROFIBUS, or Ethernet/IP integration is required, consider the Bently Nevada 3500/42M or Emerson CSI 6500 instead.
- Budget constraints: For non-critical auxiliary machinery, the Metrix MX2033 offers a cost-effective alternative.
- Regulatory compliance: For SIL-rated or API 670 mandatory installations, only use certified equivalents with documented compliance.
- Lead time sensitivity: Konmask.com maintains stock of both OEM and compatible units — contact us for availability.

Replacement & Compatibility FAQ
Q: Is the C6682 the same as the 6682?
A: Yes — C6682 is the catalog prefix variant of the same module. Both share identical hardware and firmware. Always verify the full part number including any revision suffix.
Q: Can I replace the ENTEK 6682 with a Bently Nevada 3500/42M directly?
A: Functionally similar, but not a direct plug-in replacement. Rack wiring, probe driver compatibility, and relay logic must be re-verified. Engineering review is recommended.
Q: Does Konmask.com provide warranty on replacement units?
A: Yes — we offer a standard 12-month warranty on all units. Extended warranty options are available upon request.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. For sourced or refurbished units, lead time is 2–4 weeks. Contact us for current availability.
Q: Can you provide calibration certificates?
A: Calibration certificates are available for select units. Please specify this requirement at the time of inquiry.
