Bently Nevada 24765-03-01 – Case Expansion Transducer Assembly | 3500 Series Vibration Monitoring Platform
Engineering Background
The Bently Nevada 24765-03-01 is a precision-engineered Case Expansion Transducer Assembly designed for continuous, real-time measurement of turbomachinery casing thermal growth and differential expansion. Developed under Bently Nevada’s industry-leading 3500 Series machinery protection platform, this transducer assembly delivers the measurement accuracy and long-term reliability demanded by power generation, petrochemical, and oil & gas facilities operating critical rotating equipment around the clock.
Product Positioning
Procurement engineers and reliability teams specify the 24765-03-01 when they require a drop-in, OEM-grade replacement or new-installation transducer that integrates natively with the Bently Nevada 3500 rack system. Its robust construction and factory-calibrated output eliminate field calibration overhead and reduce commissioning time, making it the preferred choice for planned turnaround projects and emergency replacement scenarios alike.

Proven Application Environments
- Steam & Gas Turbines – Monitors casing growth during start-up, load changes, and shutdown to prevent rub events and blade-tip clearance violations.
- Centrifugal Compressors – Tracks differential expansion between rotor and casing in LNG trains, ethylene crackers, and air separation units.
- Large Pumps & Fans – Provides axial position feedback for machinery protection interlock logic in power plant BOP systems.
- Hydro Turbines – Measures shaft and casing displacement in run-of-river and pumped-storage installations.
- Industrial Gearboxes – Detects thermal growth misalignment in high-speed gear trains coupled to process compressors.
Engineering Advantages
- Native 3500 Integration – Plug-and-play compatibility with the 3500/45 Position Monitor; no signal conditioning adapters required.
- Factory Calibration – Each assembly ships with a calibration certificate traceable to NIST standards, eliminating on-site calibration loops.
- Robust Mechanical Design – Stainless-steel housing and armored cable withstand high-vibration, high-temperature turbine environments.
- Long Service Life – Non-contact sensing principle eliminates mechanical wear; MTBF exceeds 100,000 hours in typical installations.
- Reduced Commissioning Time – Pre-assembled and pre-tested; ready for installation directly from the box.
- Wide Temperature Range – Qualified for operation from arctic cold-start conditions to high-temperature turbine casings.
System Architecture & Signal Flow
The 24765-03-01 transducer assembly connects directly to the Bently Nevada 3500 rack via a dedicated I/O module. The transducer generates an analog displacement signal that is conditioned by the 3500/45 Position Monitor, which applies configurable alert and danger setpoints. Trip outputs are wired to the plant DCS or safety instrumented system (SIS) for automated machinery protection. The 3500 rack communicates machinery health data upstream via Modbus RTU, Modbus TCP, or OPC-DA/UA to historian and asset management platforms such as System 1 or third-party CMMS solutions.
Sourcing & Quality Verification
- All units sourced through authorized Bently Nevada / Baker Hughes distribution channels or verified surplus with full traceability documentation.
- Each unit undergoes incoming inspection: visual, dimensional, and functional verification against OEM datasheet parameters before shipment.

Technical FAQ
Q: Is the 24765-03-01 compatible with the Bently Nevada 3500/40M monitor?
A: The 24765-03-01 is designed for the 3500/45 Position Monitor. Compatibility with the 3500/40M depends on your rack I/O configuration. Contact our technical team with your rack part number for confirmation.
Q: Can this transducer be used for radial vibration measurement?
A: No. The 24765-03-01 is specifically designed for axial displacement (case expansion / differential expansion) measurement. For radial vibration, refer to Bently Nevada’s 3300 or 3500 series proximity transducer systems.
Q: What cable length options are available?
A: The standard assembly includes a fixed cable length. Custom cable extensions are available through Bently Nevada’s extension cable catalog. Contact us with your required total system length.
Q: Do you provide a calibration certificate?
A: Yes. A calibration certificate is included with every unit. Factory test reports are available upon request for units with full traceability documentation.
Q: What is the lead time for bulk orders?
A: Standard stock orders ship within 3–5 business days. For bulk quantities (>5 units), please contact us for lead time and volume pricing.
