3500/25-SIL2-02-01-R0 Bently Nevada Keyphasor Module

Suffix Breakdown & Model Matrix

The official Bently Nevada 3500/25 ordering format is 3500/25-AA-BB-CC. The supplied 3500/25-SIL2-02-01-R0 identifier does not directly match that published ordering format, so the individual suffix meanings cannot be assigned without the applicable product record. Bently Nevada documentation does, however, identify 3500/25 SIL2 configurations as Keyphasor modules. (Baker Hughes DAM)

Keyphasor Signal and Rotor Dynamics

The 3500/25 receives once-per-turn or multiple-event-per-turn pulse signals and converts them into digital timing information for the rack. The resulting phase reference supports speed, phase, tracking-filter, and other machinery measurements. (贝克休斯)

For Bently Nevada TSI applications, correct probe signal conditioning remains important for rotor-dynamics measurements. Eddy-current probe scaling and gap-voltage validation should follow the applicable transducer documentation rather than being inferred from the module order code. The commonly used negative gap-voltage target for Bently Nevada proximity systems should likewise be verified against the specific probe and Proximitor configuration.

Frequently Asked Questions

Q: Is the 3500/25 the rack power supply module?
A: No. Bently Nevada identifies the 3500/25 as a Keyphasor module. The 3500/15 provides the dedicated AC or DC rack power-supply function. (Baker Hughes DAM)

Q: How many Keyphasor transducers can a 3500 rack support?
A: The 3500 system can accommodate up to four Keyphasor transducers by installing two 3500/25 modules in the rack. (贝克休斯)

Q: Can the 3500/25 provide phase information for vibration measurements?
A: Yes. The module supplies digital Keyphasor timing used by monitor modules for speed, phase, 1X vibration amplitude and related machinery measurements. (贝克休斯)

Field Installation Guidelines

• Install the module only in the designated 3500 rack position specified by the system configuration.
• Verify the module type and I/O termination arrangement before applying power.
• Route probe wiring separately from high-current switching conductors where practical.
• Maintain the specified cable type, shielding, grounding, and termination practices for the connected transducer.
• Verify proximity-probe gap voltage and signal amplitude against the applicable Bently Nevada transducer documentation before commissioning.
• Confirm the rack configuration and SIL requirements before placing the system into a safety-related monitoring function.
• Do not treat the 3500/25-SIL2-02-01-R0 order-code segments as independently configurable parameters unless the corresponding Bently Nevada documentation confirms their meaning.
