Vibration Monitoring Solution – Bently Nevada 24765-01-00 | 3500 Series Proximitor I/O Module
The Bently Nevada 24765-01-00 is a Proximitor I/O Module designed for the 3500 Series machinery protection system. It serves as the critical interface between proximity probes and the 3500 rack, enabling continuous, real-time vibration and position monitoring for rotating machinery in demanding industrial environments.
Where This Product Is Used
The 24765-01-00 is deployed across a wide range of heavy-industry applications where rotating machinery protection is mission-critical:
- Gas & Steam Turbines – Shaft radial vibration and axial position monitoring to prevent catastrophic failure.
- Centrifugal & Axial Compressors – Real-time displacement measurement for compressor trains in oil & gas plants.
- Pumps & Fans – Continuous bearing health monitoring in power generation and water treatment facilities.
- Gearboxes – Gear mesh frequency and shaft orbit analysis in petrochemical and refining operations.
- Marine Propulsion Systems – Shaft monitoring on vessels requiring ABS/DNV-certified protection systems.
- LNG & Offshore Platforms – Hazardous-area machinery protection where SIL-rated systems are mandated.

Application-Specific FAQ
Q: Is the 24765-01-00 compatible with the 3500/42M monitor card?
A: Yes. The 24765-01-00 Proximitor I/O Module interfaces directly with the 3500/42M 4-channel radial vibration monitor within the same 3500 rack.
Q: Can this module be used with non-Bently Nevada proximity probes?
A: It is optimized for Bently Nevada 3300 XL and 7200 series probes. Third-party probes with matching sensitivity (–200 mV/mil or –7.87 V/mm) may be compatible but require validation.
Q: What is the difference between 24765-01-00 and 24765-02-00?
A: The -02-00 suffix denotes a hardware revision with minor PCB or firmware updates. Functionally both are interchangeable in standard 3500 rack configurations. Confirm with your system integrator for SIL-rated loops.
Q: Do you provide calibration certificates?
A: Yes. Calibration certificates traceable to NIST/PTB standards are available upon request for an additional fee.
Q: Can this part be shipped internationally?
A: All exports comply with applicable trade regulations including EAR. We will advise on any restrictions at the time of order.
