General Information

Core Description

RS900106-05-30-05-02-00 is a Bently Nevada industrial proximity transducer probe featuring an extended 300mm overall case length and a 50mm unthreaded section. Specially optimized for extra deep-bore mounting applications, this rugged assembly works seamlessly inside thick fluid-film bearing walls to deliver flexible gap adjustment capabilities and stable machinery displacement protection.

Specific Application

• Gear Mesh and Casing Vibration Monitoring: Connecting high-frequency casing accelerometers mounted on heavy industrial gearboxes and multi-stage pumps to remote monitoring racks.
• Severe Mechanical Wear Cable Routing: Shielding signal paths from physical abrasions, sharp casing edges, or fly-debris using a flexible stainless steel outer armor layer.
• High-Noise Industrial Plant Environments: Reducing electrical noise interference across an 85-foot route using a 22 AWG shielded triad wire topology.

System Compatibility & Alternative Models

• System Compatibility: Fully compatible with Bently Nevada 3300 XL Proximitor Sensors (e.g., 330180), standard 3300 XL extension cable assemblies, and multi-channel 3500 protection rack panels. It completely complies with API 670 industry baseline standards for non-contact eddy current monitoring loops.
• Alternative Model: RS900106-00-30-05-02-00
• Key Differences: The RS900106-05-30-05-02-00 integrates a 50mm unthreaded forward section code (05), allowing technicians to slide the sensor head deeply through outer bracket bores without catching threads. Conversely, the alternative RS900106-00-30-05-02-00 model variant specifies an unthreaded option code of 00 (0mm unthreaded), rendering the full length of its 300mm steel case fully threaded from the rear adapter down to the active face.

Installation & Troubleshooting FAQ

Q1: What is the correct gapping protocol for setting up this extra-long case proximity probe?
A: For standard industrial target setups, the initial field calibration voltage must be adjusted to -10.0 VDC. This parameter represents the midpoint of the sensor loop's 2.0 mm (80 mils) linear operating window. Connect a digital multimeter to your Proximitor driver across its OUT and COM terminals, then slowly rotate the 300mm case into your mounting tap until the multimeter registers -10.0 VDC before locking down the jam nut.

Q2: Why am I getting high shaft runout metrics or false dynamic vibration spikes during slow-roll barring cycles?
A: This symptom points directly to electrical or mechanical runout anomalies on your shaft's measurement track. Eddy current fields are highly sensitive to microscopic surface defects. Scratches, oxide rust layers, residual magnetism, or localized heat-treatment variations on your rotor path are incorrectly captured by the tip as dynamic movement. Ensure the path is precision-ground and demagnetized to API 670 parameters, or activate slow-roll runout software compensation loops.

Q3: How much surrounding metal clearance is required to prevent a localized housing side-effect error?
A: If the deep counterbore bore diameter around your active sensor head is too narrow, a side-effect signal distortion will occur. The high-frequency electromagnetic field emitted from the probe tip couples directly into the surrounding metallic walls, compressing your calibration slope. You must maintain a continuous counterbore clearance diameter measuring at least three times the footprint of your tip to isolate the measurement fields.
