Product Details

22810-00-04-10-02 Product Description

The Bently Nevada 22810-00-04-10-02 is a precision eddy-current proximity probe engineered for seamless integration into the Bently Nevada 3500 Series machinery protection and condition monitoring architecture. Designed to deliver continuous, high-resolution shaft displacement and vibration data, this probe serves as a foundational sensing element within multi-layer industrial control systems deployed across rotating machinery in power generation, petrochemical processing, oil and gas compression, and heavy manufacturing environments. Its system-matched design ensures signal fidelity, architectural consistency, and long-term operational reliability across the full 3500 platform.

The 22810-00-04-10-02 proximity probe is not a standalone sensor — it is a precision input node within a tightly integrated Bently Nevada 3500 machinery protection architecture. Its signal chain begins at the probe tip and flows through a matched Bently Nevada TK81 or TK3E extension cable into a 3500/42M Proximitor I/O Module, where the raw gap voltage is conditioned, scaled, and validated before being passed to the 3500/20 Rack Interface Module for system-level arbitration.

Within the 3500 rack, the probe's displacement data is processed alongside inputs from companion sensors such as the Bently Nevada 330180-91-00 velocity transducer and 330104-00-06-10-02-00 proximity probes used for axial position monitoring. The 3500/15 Power Supply Module provides regulated -24 VDC to the Proximitor driver circuits, ensuring stable excitation voltage across all probe channels simultaneously. For redundant protection architectures, dual-probe configurations using matched 22810-series probes are deployed on both X and Y axes of critical rotating shafts, with the 3500/42M module performing automated gap validation and alert/danger threshold arbitration.

System communication is handled through the 3500/22M Transient Data Interface or the 3500/92 Communication Gateway, which bridges the rack's internal data bus to plant-level DCS platforms such as Emerson DeltaV or Honeywell Experion via Modbus TCP or OPC-DA/UA protocols. This contextual integration allows vibration and displacement data from the 22810-00-04-10-02 to be surfaced in real time on operator HMI stations, enabling condition-based maintenance decisions without manual data extraction. The 3500/95 Display Interface Module provides local rack-level visualization for commissioning and field diagnostics.

For installations requiring enhanced diagnostics, the probe's signal can be routed simultaneously to a System 1 Condition Monitoring Software node via the 3500/92 gateway, enabling full spectrum analysis, trend logging, and predictive maintenance alerting. This architecture supports modular expansion — additional 3500 rack slots can accommodate I/O modules for temperature (3500/60), speed (3500/25), and process variable monitoring without disrupting existing probe wiring or calibration.

Power Generation: In steam and gas turbine protection systems, the 22810-00-04-10-02 is deployed on HP/LP turbine shaft journals to monitor radial vibration and shaft centerline position. Paired with the 3500/42M and 3500/15 power supply, it provides the continuous displacement data required for API 670-compliant machinery protection, triggering automatic shutdown sequences when vibration exceeds danger setpoints.

Petrochemical & Refinery Compressor Trains: Centrifugal and reciprocating compressors in ethylene, ammonia, and LNG facilities rely on matched proximity probe arrays to detect rotor instability, oil whirl, and bearing wear. The 22810-series probes, integrated with the 3500/42M and System 1 software, enable continuous online monitoring without process interruption, supporting API 670 and ISO 13373 compliance requirements.

Water Treatment & Pumping Stations: Large vertical turbine pumps and booster pump stations use proximity probes to detect shaft misalignment and bearing degradation before catastrophic failure. The 3500 architecture's modular I/O design allows the 22810-00-04-10-02 to be integrated into existing SCADA systems via Modbus, providing plant operators with real-time shaft health data at the control room level.

Mining & Minerals Processing: Ball mills, SAG mills, and large fan drives in mining operations generate high vibration environments that demand robust, high-temperature-rated proximity probes. The 22810-00-04-10-02's IP67 rating and wide operating temperature range make it suitable for dusty, high-humidity mill environments, while its integration with the 3500 rack enables centralized monitoring of multiple rotating assets from a single control room.

Marine & Offshore Platforms: Shipboard propulsion systems and offshore gas compression modules require vibration monitoring systems certified for marine environments. The Bently Nevada 3500 architecture, anchored by 22810-series proximity probes, supports DNV and ABS classification requirements, providing continuous shaft monitoring for main engines, gearboxes, and auxiliary machinery.

Q1: Is the 22810-00-04-10-02 directly compatible with the Bently Nevada 3500/42M Proximitor I/O Module without additional signal conditioning? Yes. The 22810-00-04-10-02 is factory-matched to the 3500/42M module's input specifications, including the -24 VDC excitation voltage and 200 mV/mil sensitivity standard. No external signal conditioner is required. The probe connects via a TK81 or TK3E extension cable to the 3500/42M's BNC input, and the module performs all gap validation, scaling, and alert threshold processing internally. Ensure the extension cable length is accounted for in the system's overall linear range calibration.

Q2: Can this probe be used in a redundant dual-probe XY configuration for API 670 compliance, and what additional components are required? Yes. API 670 requires dual XY proximity probe pairs on each monitored bearing journal. A second matched 22810-series probe (typically 22810-00-04-10-02 or equivalent 8 mm tip variant) is mounted 90° from the first. Both probes connect to separate input channels on the 3500/42M module, which performs independent channel monitoring and cross-channel validation. The 3500/15 power supply must be sized to support the additional Proximitor current draw. For full redundancy, a dual-power-supply configuration using two 3500/15 modules in a hot-standby arrangement is recommended for critical machinery protection applications.

Q3: What is the warranty coverage and pre-shipment testing process for the 22810-00-04-10-02, and how is long-term spare parts availability managed? Every 22810-00-04-10-02 unit supplied by NANKMOS carries a 12-Month Warranty covering manufacturing defects and functional performance. Prior to shipment, each probe undergoes a pre-shipment functional test verifying tip sensitivity (200 mV/mil ±1%), linear range, cable continuity, and connector integrity. Units are shipped with test documentation upon request. For long-term maintenance planning, NANKMOS maintains inventory of 22810-series probes and compatible 3500 rack components including TK extension cables, 3500/42M modules, and 3500/15 power supplies, supporting multi-year spare parts programs for critical rotating machinery fleets.
