Overview
The Bently Nevada 46000-01, also cataloged as the 46000-01 Magnetic Base, provides temporary mechanical mounting for vibration and velocity sensors on ferrous surfaces. Its 1/4-28 UNF mounting thread connects compatible sensor hardware while the magnetic base maintains contact with the machine surface.

Mechanical Vibration Mounting Interface
The 46000-01 transfers the sensor mounting interface directly to a ferrous machine surface. The magnetic coupling allows technicians to position, remove, and reposition the sensor without drilling or permanently modifying the mounting surface.
For vibration measurements, the mounting surface should be clean and mechanically stable. Remove loose scale, heavy contamination, and debris before attachment. The sensor should seat firmly against the mounting base to minimize mechanical movement during measurement.
The 1/4-28 UNF thread provides the specified mechanical connection between the magnetic base and compatible sensor hardware. The supplied data identifies the base for Bently Nevada vibration and velocity sensor applications, but it does not define a complete sensor compatibility matrix.
Frequently Asked Questions
Q: Does the 46000-01 require an electrical power supply?
A: No. The 46000-01 is a passive magnetic mounting component and has no specified electrical power connection.
Q: What type of machine surface can accept the magnetic base?
A: The supplied specification identifies ferrous metal surfaces. Non-ferrous surfaces do not provide the specified magnetic mounting condition.
Q: What mounting thread does the 46000-01 provide?
A: The supplied data specifies a 1/4-28 UNF mounting thread for sensor attachment.
Field Installation Guidelines
- Clean the selected ferrous mounting surface before installation. Remove loose particles, scale, oil, and other material that can reduce mechanical contact.
- Confirm that the mounting location provides a flat and stable interface for the magnetic base.
- Attach the compatible sensor to the 1/4-28 UNF mounting thread and tighten it according to the sensor manufacturer’s specified installation procedure.
- Place the magnetic base firmly against the prepared ferrous surface.
- Route the sensor cable so that it does not apply pulling force or lateral loading to the sensor or magnetic base.
- Keep sensor wiring separated from sources of mechanical interference and avoid unnecessary cable movement during vibration measurements.
- Verify that the magnetic base remains firmly seated before collecting measurement data.
- For temporary measurements, remove the assembly carefully and inspect the mounting interface before relocating it.
