Product Details

200350-12-00-01 Product Description

The Bently Nevada 200350-12-00-01 is a precision industrial accelerometer engineered for seamless integration within the Bently Nevada 3500 Series machinery protection and condition monitoring architecture. Designed to deliver high-fidelity vibration signal acquisition from rotating equipment, this accelerometer serves as the primary sensing element at the field layer of a multi-tier industrial control system. Its role extends beyond simple vibration detection — it functions as a critical data source that feeds into the broader machinery protection ecosystem, enabling real-time diagnostics, predictive maintenance, and system-wide condition awareness across power generation, petrochemical, oil & gas, water treatment, mining, and marine propulsion environments.

Within a fully integrated automation architecture, the 200350-12-00-01 connects directly to Bently Nevada 3500/42M Proximitor/Seismic Monitor modules housed in the 3500 rack system. The rack's modular backplane distributes conditioned signals to the 3500/01 Rack Interface Module, which manages communication between field instruments and the plant-level control network. This layered signal flow — from sensor to monitor module to rack interface to DCS or SCADA — ensures that vibration data is captured, conditioned, and transmitted with minimal latency and maximum integrity.

All units are supplied in-stock, pre-shipment tested, and covered by a 12-Month Warranty, ensuring operational confidence from day one of deployment.

The 200350-12-00-01 accelerometer is most effective when deployed as part of a complete Bently Nevada 3500 Series machinery protection platform. In a typical turbomachinery or compressor train installation, the accelerometer mounts on the bearing housing and feeds its analog signal into the Bently Nevada 3500/42M Proximitor/Seismic Monitor, which performs signal conditioning, alarm threshold evaluation, and danger relay actuation. The 3500/42M resides within the Bently Nevada 3500/05 Rack, a modular 19-inch DIN-rail-compatible enclosure that supports up to 16 monitor modules on a shared backplane.

The rack's 3500/01 Rack Interface Module (RIM) aggregates all monitor data and provides the communication gateway to plant-level systems. Depending on the plant architecture, the RIM can interface with a DeltaV DCS, Honeywell Experion PKS, or Yokogawa CENTUM VP via Modbus RTU, Modbus TCP/IP, or OPC-DA/OPC-UA protocols, enabling seamless integration into the plant's SCADA and historian infrastructure. For facilities running Bently Nevada System 1 Evolution software, the 3500 rack communicates directly over Ethernet, delivering real-time waveform data, trend plots, and alarm event logs to the condition monitoring workstation.

In redundant protection architectures, the 200350-12-00-01 may be paired with a Bently Nevada 3300 XL 8mm Proximity Transducer System (comprising the 3300 XL probe, extension cable, and proximitor driver) to provide complementary radial shaft displacement monitoring alongside seismic casing vibration. This dual-parameter approach — combining proximity-based shaft orbit analysis with accelerometer-based casing vibration — is standard practice in API 670-compliant machinery protection systems for critical rotating equipment.

Additional system components that commonly co-exist in the same control cabinet or rack enclosure include the Bently Nevada 3500/15 Power Supply Module (providing redundant 24 VDC rail power to all monitor modules), the 3500/22M Transient Data Interface (for high-speed waveform capture during startup and shutdown transients), and the 3500/32 4-Channel Relay Module (for hardwired danger and alert relay outputs to the plant's emergency shutdown system). Signal integrity across the entire chain — from the 200350-12-00-01 sensor through the monitor module to the relay output — is maintained by the rack's internal backplane, eliminating the need for external signal conditioning or isolation barriers in most standard installations.

For installations requiring signal isolation or protocol conversion at the I/O boundary, a Phoenix Contact MACX Analog signal isolator or a Pepperl+Fuchs KFD2-series intrinsic safety barrier may be inserted between the field sensor and the monitor input, particularly in Zone 1 or Zone 2 hazardous area classifications. Communication to higher-level MES or ERP systems is typically routed through an industrial Ethernet switch (such as a Hirschmann MICE or Moxa EDS series) installed in the same control cabinet, ensuring deterministic network performance and VLAN segmentation between the safety instrumented system and the process control network.

Power Generation: In gas turbine and steam turbine installations, the 200350-12-00-01 monitors casing vibration on the turbine bearing pedestals. Combined with the 3500/42M monitor and System 1 software, operators receive continuous vibration trend data that enables early detection of rotor imbalance, blade fouling, and bearing degradation — reducing unplanned outages and extending overhaul intervals.

Petrochemical & Oil and Gas: On centrifugal compressors and pumps in API 670-compliant installations, the accelerometer provides the seismic vibration channel required alongside radial and axial proximity measurements. The 3500 rack's relay outputs connect directly to the plant's Safety Instrumented System (SIS), enabling automatic machine trip on high-vibration danger conditions without DCS intervention.

Water Treatment & Utilities: Large vertical turbine pumps and blower trains in water treatment facilities benefit from continuous vibration monitoring to detect cavitation, impeller wear, and structural resonance. The 200350-12-00-01's robust IP67 construction withstands the humid, chemically aggressive environments typical of pump stations and aeration basins.

Mining & Minerals Processing: Ball mills, SAG mills, and conveyor drive gearboxes in mining operations generate complex vibration signatures that require high-sensitivity accelerometers. The 200350-12-00-01, integrated with the 3500 Series rack, provides the signal fidelity needed to distinguish normal operational vibration from early-stage gear tooth wear or bearing race defects.

Marine Propulsion & Offshore: Shipboard diesel generators, propulsion motors, and auxiliary machinery require vibration monitoring that meets DNV GL or ABS class requirements. The 200350-12-00-01's wide operating temperature range and sealed construction make it suitable for engine room installations where temperature cycling and vibration exposure are severe.

Q1: Is the Bently Nevada 200350-12-00-01 directly compatible with the 3500/42M Proximitor/Seismic Monitor without additional signal conditioning? Yes. The 200350-12-00-01 is designed as a system-matched accelerometer for the Bently Nevada 3500 Series platform. It connects directly to the 3500/42M monitor module's seismic input channel via standard coaxial cable, with the monitor providing the required IEPE constant-current excitation. No external signal conditioner or isolation barrier is required in standard non-hazardous area installations. For Zone 1/Zone 2 hazardous area applications, an appropriate intrinsic safety barrier should be inserted per the applicable area classification standard (IEC 60079-14).

Q2: Can this accelerometer be integrated into a DCS or SCADA system alongside other 3500 Series monitor modules? Absolutely. The 200350-12-00-01 feeds its vibration data into the 3500/42M monitor, which in turn communicates through the 3500/01 Rack Interface Module (RIM) to the plant network. The RIM supports Modbus RTU, Modbus TCP/IP, and OPC-UA communication, making it compatible with all major DCS platforms including DeltaV, Honeywell Experion, Yokogawa CENTUM VP, and ABB 800xA. For advanced condition monitoring, the rack integrates natively with Bently Nevada System 1 Evolution software over Ethernet, providing waveform, spectrum, and trend data to the condition monitoring workstation.
