Product Details

21000-16-10-00-113-03-02 Product Description

The Bently Nevada 21000-16-10-00-113-03-02 is a precision-engineered proximity probe housing assembly designed for seamless integration within the Bently Nevada 21000 Series machinery protection and condition monitoring platform. As a critical mechanical interface component, this probe housing ensures accurate eddy-current signal transmission from rotating machinery surfaces to the monitoring rack, maintaining signal integrity across the full control architecture. Backed by a 12-Month Warranty and verified through pre-shipment functional testing, this unit is ready for immediate deployment in demanding industrial environments.

In modern industrial automation, machinery protection systems do not operate in isolation. The 21000-16-10-00-113-03-02 probe housing serves as the field-level anchor of a layered monitoring architecture that spans from the physical transducer interface through signal conditioning, rack-level processing, communication gateways, and ultimately to supervisory control and HMI platforms. Its role in maintaining Contextual Integration across these layers is fundamental to system reliability, diagnostic accuracy, and long-term maintenance efficiency.

The 21000-16-10-00-113-03-02 probe housing is most effective when understood within the context of a complete Bently Nevada machinery protection architecture. At the transducer layer, this housing pairs directly with compatible Bently Nevada 21000 Series proximity probes and extension cables (such as the 21000-00-55-10-02 cable assembly) to form a complete eddy-current sensing chain. The mechanical housing ensures precise probe-to-target gap alignment, which is critical for accurate vibration amplitude and shaft position readings.

Moving up to the signal conditioning layer, the analog output from this probe assembly feeds into Bently Nevada 3500/40M proximitor monitors or equivalent 21000 Series rack-mounted signal conditioners. These modules convert raw proximity signals into calibrated engineering units — displacement in mils or micrometers — that are then processed by the 3500 Series rack backplane and distributed to protection logic modules such as the 3500/20 Rack Interface Module (RIM).

At the communication and integration layer, the 3500 Series rack interfaces with plant-level DCS or PLC systems via the 3500/92 Communication Gateway Module, supporting Modbus RTU, Modbus TCP, and FOUNDATION Fieldbus protocols. This enables the vibration and position data captured by the 21000-16-10-00-113-03-02 assembly to be consumed by GE/Baker Hughes System 1 Evolution condition monitoring software, providing operators with real-time trend analysis, alarm management, and predictive maintenance insights.

For HMI and supervisory control integration, System 1 data streams can be forwarded to Wonderware InTouch, Ignition SCADA, or plant historians via OPC-DA/OPC-UA interfaces, completing the data path from the physical probe housing to the enterprise monitoring layer. In redundant architectures, dual-probe configurations using paired 21000 Series housings provide voting logic inputs to the 3500/33 16-Channel Relay Module, enabling 1oo2 or 2oo3 trip logic for critical machinery protection.

Power supply integrity for the monitoring rack is maintained by Bently Nevada 3500/15 Power Supply Modules, which provide regulated DC power to all rack-mounted monitors and communication modules. In high-availability installations, redundant power supply configurations ensure continuous monitoring even during single power supply failures — a key requirement in petrochemical, power generation, and offshore platform applications.

Power Generation & Turbomachinery: In gas turbine and steam turbine protection systems, the 21000-16-10-00-113-03-02 housing is deployed on journal bearing positions to monitor radial shaft vibration and rotor eccentricity. Continuous proximity data feeds turbine protection logic, enabling automatic trip initiation before bearing damage thresholds are exceeded. This application is standard in combined-cycle power plants, cogeneration facilities, and utility-scale generation assets.

Petrochemical & Refinery Compressor Trains: Centrifugal and reciprocating compressor trains in refinery service require continuous shaft monitoring across multiple bearing planes. The 21000 Series probe housing assemblies are installed at each bearing location, with data aggregated at the 3500 Series rack and transmitted to the plant DCS for integration with process safety systems (SIS). This architecture supports IEC 61511 functional safety requirements for machinery protection loops.

Water & Wastewater Treatment: Large vertical pump motors and blower units in municipal water treatment facilities benefit from non-contact proximity monitoring to detect shaft runout, bearing wear, and rotor imbalance without interrupting continuous operation. The 21000-16-10-00-113-03-02 housing's robust mechanical design withstands humid, chemically aggressive environments typical of water treatment infrastructure.

Mining & Mineral Processing: Ball mills, SAG mills, and large conveyor drive motors in mining operations are subject to high vibration loads and harsh environmental conditions. Proximity probe assemblies in the 21000 Series provide reliable shaft monitoring in these demanding applications, supporting predictive maintenance programs that reduce unplanned downtime and extend equipment service life.

Marine & Offshore Platforms: Shipboard propulsion systems, diesel generator sets, and offshore platform compressors require machinery protection systems certified for marine environments. The Bently Nevada 21000 Series platform, including this probe housing assembly, is widely deployed in marine and offshore applications where equipment reliability directly impacts operational safety and regulatory compliance.

Q1: Is the 21000-16-10-00-113-03-02 probe housing compatible with the Bently Nevada 3500 Series monitoring rack? Yes. The 21000 Series probe housings and extension cables are designed for full compatibility with the Bently Nevada 3500 Series rack-mounted monitors, including the 3500/40M, 3500/42M, and 3500/45 monitor modules. The analog proximity signal output from the 21000 Series transducer chain meets the input specifications of 3500 Series proximitor monitors, ensuring accurate signal conditioning and alarm processing without additional interface hardware. For system configuration verification, consult the Bently Nevada 3500 Series System Rack Installation Manual alongside the 21000 Series probe specification sheet.

Q2: What installation and commissioning considerations apply to this probe housing in a redundant machinery protection architecture? When deploying the 21000-16-10-00-113-03-02 in a redundant monitoring configuration, precise gap setting is critical. The probe-to-target gap must be set within the linear range of the eddy-current system — typically 1.0 mm to 2.0 mm for standard 21000 Series probes — using a calibrated gap voltage measurement at the proximitor output. In dual-probe redundant installations, both probes must be independently gapped and verified before rack commissioning. NANKMOS recommends performing a full signal chain verification test, including static gap voltage check and dynamic runout measurement, prior to system handover. Our technical team can provide commissioning support documentation upon request.

Q3: What does the 12-Month Warranty cover, and how does NANKMOS ensure product quality before shipment? All Bently Nevada 21000-16-10-00-113-03-02 units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment. This warranty covers manufacturing defects, material failures, and functional non-conformance under normal operating conditions. Prior to shipment, each unit undergoes a pre-shipment functional inspection to verify mechanical integrity, thread condition, and dimensional conformance to Bently Nevada specifications. Units that do not pass inspection are quarantined and not shipped. In the event of a warranty claim, NANKMOS provides replacement or repair support with documented RMA procedures. For long-term maintenance planning, we also maintain inventory of related 21000 Series components to support ongoing spare parts requirements.
