Bently Nevada 136751-01 3500 Dual Velocity Monitor

Hardware Specifications

Mechanical Monitoring and Signal Processing

The 136751-01 provides two vibration velocity input channels for the 3500 monitoring architecture. The input signals represent mechanical vibration behavior from rotating equipment. The module operates as part of the rack-based monitoring chain rather than as a standalone field measuring instrument.

For Bently Nevada machinery monitoring, signal conditioning and channel configuration must match the installed sensor type and the associated 3500 monitor configuration. Sensor scaling, signal reference, and channel assignment should therefore be verified against the applicable system documentation before commissioning.

Frequently Asked Questions

Q: Is the 136751-01 a standalone vibration transmitter?
A: No. It is a 3500 Series rack module intended to operate within the compatible monitoring system and rack configuration.

Q: How many input channels does the module provide?
A: The supplied specification identifies two vibration and velocity input channels.

Q: Is the power consumption specified for the 136751-01?
A: No. The supplied data does not provide a verified power-consumption value. The rack documentation should be used for electrical loading information.

Field Installation Guidelines

Install the module only in a compatible Bently Nevada 3500 rack position. Verify the rack configuration and module identification before applying power.

Confirm that field sensor wiring corresponds to the configured input channels. Keep vibration signal wiring separated from high-current power conductors and other sources of electrical interference where practical.

Use the specified cable shielding and grounding arrangement defined by the applicable Bently Nevada installation documentation. Avoid creating unintended shield-ground loops.

Before commissioning, verify channel assignment, sensor compatibility, signal scaling, alarm configuration, and monitor communication. Confirm that the measured signal corresponds to the intended mechanical measurement point.

Do not assume hot-swap capability, rack current consumption, connector pin assignments, or hazardous-area certification from the supplied data alone. These parameters require verification against the applicable 3500 system documentation and module revision.
