Product Details

22811-01-06-10-02 Product Description

The Bently Nevada 22811-01-06-10-02 Acceleration Transducer is engineered as a precision sensing node within the Bently Nevada 3500 Machinery Protection System — one of the most widely deployed condition monitoring architectures in rotating equipment industries. Rather than functioning as a standalone sensor, this transducer is designed for deep contextual integration across the full automation stack, delivering real-time acceleration data that feeds directly into the 3500 rack's signal processing and alarm management layers.

At the control and monitoring layer, the 22811-01-06-10-02 interfaces seamlessly with the Bently Nevada 3500/42M Proximitor/Seismic Monitor and the 3500/45 Position Monitor, enabling multi-channel vibration and acceleration surveillance across critical rotating assets. The transducer's analog output is conditioned and digitized within the 3500 rack, where it is processed alongside proximity probe signals from the Bently Nevada 3300 XL 8mm Proximity Transducer System to provide a comprehensive view of shaft and casing dynamics.

At the I/O and signal layer, the transducer integrates with the 3500/20 Rack Interface Module (RIM), which governs communication between the field-mounted sensors and the central monitoring rack. The RIM ensures that acceleration data is time-stamped, buffered, and transmitted without signal degradation — a critical requirement in high-speed machinery environments such as gas turbines, compressors, and steam turbines. For applications requiring enhanced signal isolation, the Bently Nevada 3500/15 Power Supply Module provides stable, noise-filtered excitation to the transducer circuit, maintaining measurement integrity across long cable runs.

At the communication layer, the 3500 rack — hosting the 22811-01-06-10-02 — connects to plant-level SCADA and DCS platforms via the 3500/92 Communication Gateway Module, supporting Modbus TCP, OPC-DA, and Ethernet/IP protocols. This enables the acceleration data to be consumed by distributed control systems such as the Emerson DeltaV DCS or third-party PLC platforms, ensuring that vibration trends are visible at the operator HMI level without requiring separate data acquisition hardware.

For HMI and diagnostic visualization, the transducer's data stream is natively supported by Bently Nevada System 1 Software, which provides real-time waveform analysis, spectrum plots, and alarm trending. System 1 enables engineers to correlate acceleration signatures with process variables, supporting predictive maintenance decisions and reducing unplanned downtime. When paired with the 3500/53 Overspeed Detection Module, the architecture gains an additional protective layer — ensuring that acceleration anomalies coincident with speed excursions trigger coordinated protective actions across the rack.

At the execution and protection layer, the 22811-01-06-10-02 supports integration with relay output modules such as the 3500/32 4-Channel Relay Module, which translates alarm states into hardwired trip signals for turbine trip solenoids, compressor unloaders, or emergency shutdown systems. This closed-loop architecture — from sensing through signal conditioning, communication, visualization, and protective action — exemplifies the system-level value of deploying the 22811-01-06-10-02 within a fully configured 3500 platform.

For maintenance and long-term reliability, the transducer is stocked and tested prior to shipment, with each unit verified against Bently Nevada factory calibration standards. The 12-Month Warranty covers manufacturing defects and ensures that replacement units are available from inventory, minimizing lead times for critical spares programs.

The Bently Nevada 22811-01-06-10-02 Acceleration Transducer is deployed across a broad range of heavy industrial environments where rotating machinery protection is mission-critical:

Power Generation: In gas turbine and steam turbine plants, the transducer monitors casing acceleration to detect bearing defects, blade pass frequencies, and structural resonance. Integrated with the 3500 rack and System 1 software, it enables continuous online monitoring without process interruption, supporting both baseload and peaking plant operations.

Oil & Gas / Petrochemical: On centrifugal compressors and reciprocating pumps in upstream and downstream facilities, the 22811-01-06-10-02 provides high-frequency acceleration data that complements proximity probe measurements, offering a complete picture of rotor and casing dynamics. Its IP67-rated housing ensures reliable operation in humid, corrosive, and high-vibration environments.

Mining & Metallurgy: In ore processing plants and smelting facilities, the transducer is mounted on ball mills, crushers, and conveyor drive motors to detect imbalance, misalignment, and bearing wear. Early detection of these conditions reduces catastrophic failure risk and extends equipment service intervals.

Water & Wastewater Treatment: On large centrifugal pumps and blowers in municipal water infrastructure, the transducer supports condition-based maintenance programs, replacing time-based overhaul schedules with data-driven intervention strategies.

Marine & Offshore: In ship propulsion systems and offshore platform machinery, the 22811-01-06-10-02 operates reliably under the combined stresses of vibration, salt atmosphere, and temperature cycling, providing continuous machinery health data to the vessel's integrated control and monitoring system.

Packaging & Process Lines: On high-speed rotary filling machines, centrifuges, and turboblowers in food, beverage, and pharmaceutical production, the transducer enables real-time quality assurance by correlating vibration signatures with product quality metrics.

Q1: Is the Bently Nevada 22811-01-06-10-02 directly compatible with the 3500 rack without additional signal conditioning? Yes. The 22811-01-06-10-02 is designed for direct integration with the Bently Nevada 3500 Machinery Protection System. It connects to the 3500/42M Proximitor/Seismic Monitor or equivalent seismic input modules within the rack, requiring no external signal conditioners. The rack's internal power supply provides the necessary transducer excitation, and the module handles all signal scaling and alarm threshold configuration via the Rack Configuration Software (RCS).

Q2: Can this transducer be used in a redundant monitoring architecture, and how does it support long-term maintenance efficiency? The 22811-01-06-10-02 supports redundant deployment configurations when paired with dual-channel monitor modules within the 3500 rack. Each channel can be independently configured for alert and danger thresholds, and the rack's self-diagnostic capabilities continuously verify transducer loop integrity. For maintenance teams, the transducer's plug-and-play replacement design — combined with the 12-Month Warranty and pre-shipment functional testing — ensures that spare units can be installed and commissioned rapidly, minimizing mean time to repair (MTTR) in critical machinery protection applications.

Q3: What is the lead time and warranty coverage for the Bently Nevada 22811-01-06-10-02? The 22811-01-06-10-02 is maintained in stock and is available for prompt shipment following order confirmation. Each unit undergoes pre-shipment functional verification to ensure it meets Bently Nevada performance specifications. The product is covered by a 12-Month Warranty against manufacturing defects from the date of shipment.
