Description

Configured for specific non-contact displacement and vibration measurements in machinery protection networks, the Bently Nevada 46000-01 (46000 Magnetic Base) operates as a dedicated hardware component for temporary sensor attachment within vibration analysis platforms. This heavy-duty structural accessory establishes high-strength magnetic adhesion to ferrous machine components, which allows technicians to secure Velomitor and other piezo-velocity sensors directly to bearing housings. Consequently, the component routes physical mechanical casing acceleration details to the diagnostic instrumentation without requiring permanent stud drilling or adhesive compound bonding.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Calibration

Because the 46000-01 magnetic base acts as a physical interface between the machine casing and the vibration transducer, field engineers must verify the mechanical coupling path during sensor scaling procedures. While permanent studs provide direct coupling, this temporary magnetic base alters the system resonant frequency response curve. Therefore, during initial calibration loops, technicians adjust the high-frequency attenuation limits to ensure that the sensor accurately captures high-speed rotor dynamics.

Furthermore, proper surface alignment prevents cross-talk suppression failures when moving portable velocity probes across multiple check points on a single bearing housing. Clean contact with the target face prevents the transducer from rocking, which eliminates structural signal noise. As a result, maintaining rigid magnetic adhesion ensures that the asset protection platform accurately monitors synchronous casing velocity parameters and transient balance changes.

Frequently Asked Questions

Q: Does the 46000-01 magnetic base require external power to maintain its pull force?

A: No, because the hardware utilizes a high-strength permanent magnetic array, it requires no electrical excitation. Therefore, it maintains its rated 50 lbs pull force continuously across the entire operating temperature spectrum without a power supply.

Q: Can technicians mount the 46000-01 base onto aluminum or stainless steel machinery casings?

A: No, because these metals lack magnetic properties, the permanent magnetic array cannot establish physical adhesion. Consequently, field personnel must exclusively utilize the 46000-01 on carbon steel, cast iron, or other raw ferrous structural components.

Field Installation Guidelines

• Surface Preparation: Wipe down the designated machinery measurement point to remove all grit, loose paint scaling, thick oil films, or debris. A clean, flat surface ensures that the magnetic array achieves maximum rated pull force.
• Mechanical Thread Engagement: Thread the Velomitor adapter or sensor housing directly into the top 1/4-20 UNC interface hole. Ensure a minimum of 5 full thread turns of engagement, then hand-tighten the sensor body to prevent internal thread strip-out.
• Attachment Technique: Tilt the magnetic base and place one edge firmly onto the ferrous machine component. Then, lower the base flat against the housing to prevent a harsh physical impact that could crack the internal permanent magnet or damage the sensitive piezo-velocity elements inside the attached sensor.
• Cable Safety Route: Route the sensor interconnect cable using immediate physical ties or magnetic clips near the sensor assembly. This step prevents physical cable strain from pulling the magnetic base away from its target coordinates during route-based machinery data collection.
