Product Details

190501-22-00-CN Product Description

The Bently Nevada 190501-22-00-CN Velomitor CT is a high-performance velocity transducer engineered for seamless integration into the Bently Nevada 3500 Series machinery protection system. Designed to deliver accurate, low-noise velocity signals across a wide frequency range, this sensor plays a critical role in the control architecture of rotating machinery monitoring platforms deployed in power generation, petrochemical, water treatment, mining, and heavy manufacturing environments. Its robust construction and system-matched signal conditioning make it a preferred choice for engineers building or maintaining layered industrial automation architectures where signal integrity, redundancy, and long-term reliability are non-negotiable.

Within a complete automation architecture, the 190501-22-00-CN occupies the field sensing layer — the foundation upon which all higher-level control decisions are made. It interfaces directly with the 3500/42M Proximitor/Seismic Monitor module, which processes the velocity signal and communicates machine health data upward through the control hierarchy. This tight hardware-software integration ensures that the signal chain from physical vibration to control-room alarm is both accurate and deterministic, supporting the real-time decision-making demands of modern distributed control systems (DCS) and safety instrumented systems (SIS).

The 190501-22-00-CN is not a standalone component — it is a precision input node within a fully integrated machinery protection and control architecture. Understanding its role requires examining the complete signal and control flow across multiple system layers.

At the control layer, the 3500 rack system — anchored by the Bently Nevada 3500/01 Rack Interface Module and the 3500/05 Power Supply Module — provides the centralized processing backbone. The power supply module delivers conditioned DC power to all installed monitor cards, including the 3500/42M Proximitor/Seismic Monitor, which is the direct receiving module for the 190501-22-00-CN velocity signal. This tight power-signal integration eliminates ground loop interference and ensures measurement accuracy even in electrically noisy industrial environments.

At the I/O and signal layer, the Velomitor CT sensor outputs a low-impedance analog voltage signal that is inherently resistant to cable-induced noise over long field runs — a critical advantage in large plant installations where sensor-to-rack cable distances can exceed 30 meters. When paired with the 3500/42M monitor, the system supports both overall vibration level monitoring and time-waveform analysis, enabling engineers to distinguish between mechanical looseness, imbalance, misalignment, and bearing defects without additional signal conditioning hardware.

At the communication layer, the 3500 rack communicates machine health data to the plant DCS or historian via the Bently Nevada 3500/92 Communication Gateway Module, which supports Modbus TCP, OPC-DA, and proprietary TDI protocols. This allows the velocity data captured by the 190501-22-00-CN to be integrated into broader process control loops managed by platforms such as the GE Mark VIe Turbine Control System or third-party DCS platforms, enabling condition-based maintenance decisions to be made at the supervisory control level.

For installations requiring redundancy, the 3500 architecture supports dual-sensor configurations where a Bently Nevada 330500 Proximity Probe (for shaft relative vibration) is deployed alongside the 190501-22-00-CN (for casing absolute velocity), providing complementary measurement perspectives on the same machine. This dual-path approach satisfies API 670 machinery protection standards and is commonly specified for critical rotating equipment in power plants and LNG facilities.

At the HMI and visualization layer, the System 1 Evolution software platform aggregates velocity trend data from multiple 190501-22-00-CN sensors across a machine train, presenting operators with real-time spectral plots, trend overlays, and alarm annunciation. Integration with Bently Nevada System 1 Evolution also enables automated alert escalation to the plant SCADA or MES layer, closing the loop between field measurement and production management.

For terminal and wiring infrastructure, the CN-suffix connector on the 190501-22-00-CN is compatible with standard Bently Nevada field wiring assemblies, and the sensor can be mounted using the Bently Nevada 330130 Mounting Block or equivalent stud-mount adapters. Proper torque and cable dressing practices, as specified in Bently Nevada installation drawings, are essential for maintaining IP67 integrity and minimizing measurement uncertainty in high-vibration environments.

All units supplied by NANKMOS undergo pre-shipment functional testing, including sensitivity verification, frequency response sweep, and connector integrity check, backed by a 12-Month Warranty and full traceability documentation.

Power Generation: In gas turbine and steam turbine installations, the 190501-22-00-CN is mounted on bearing housings to monitor casing velocity in compliance with API 670 and ISO 10816 standards. The sensor feeds the 3500/42M monitor, which triggers automatic turbine trip signals when vibration thresholds are exceeded, protecting multi-million-dollar assets from catastrophic failure.

Petrochemical and Refining: Centrifugal compressors and process pumps in refineries operate continuously under varying load conditions. The Velomitor CT provides the high-frequency response needed to detect early-stage bearing defects and impeller resonance, enabling condition-based maintenance scheduling that reduces unplanned downtime and extends mean time between overhauls (MTBO).

Water and Wastewater Treatment: Large vertical pumps and blower units in water treatment facilities benefit from the IP67-rated housing of the 190501-22-00-CN, which withstands wash-down environments and high ambient humidity. Integration with the 3500 rack system allows remote monitoring of pump health from the plant control room, reducing the need for manual field inspections.

Mining and Mineral Processing: Ball mills, SAG mills, and conveyor drive systems in mining operations generate complex vibration signatures. The wide frequency range of the 190501-22-00-CN (2 Hz – 1,000 Hz) captures both low-speed structural resonances and high-frequency gear mesh frequencies, providing comprehensive machine health data to the plant historian for trend analysis and failure prediction.

Marine and Offshore: Shipboard propulsion systems and offshore platform compressors require sensors that maintain calibration accuracy under continuous vibration and salt-air exposure. The stainless steel housing and MIL-spec connector of the 190501-22-00-CN meet the environmental demands of marine classification society requirements, making it suitable for DNV-GL and ABS-certified machinery protection systems.

Packaging and Discrete Manufacturing: High-speed rotating equipment on packaging lines — including centrifugal fans, gearboxes, and servo-driven conveyors — can be monitored using the 190501-22-00-CN in conjunction with portable data collectors or permanently installed 3500 rack systems, enabling predictive maintenance programs that minimize production line stoppages.

Q1: Is the 190501-22-00-CN directly compatible with the Bently Nevada 3500/42M monitor without additional signal conditioning? Yes. The 190501-22-00-CN Velomitor CT is designed as a system-matched component for the Bently Nevada 3500 Series. It outputs a low-impedance analog voltage signal that is directly accepted by the 3500/42M Proximitor/Seismic Monitor input channels without requiring external signal conditioners or impedance matching networks. The CN-suffix connector variant is wired per Bently Nevada standard field wiring drawings, ensuring plug-and-play compatibility within an existing 3500 rack architecture. NANKMOS verifies this compatibility during pre-shipment functional testing.

Q2: Can the 190501-22-00-CN be used in a redundant dual-sensor architecture alongside proximity probes on the same machine? Absolutely. API 670 machinery protection standards for critical rotating equipment often specify both shaft relative vibration (measured by proximity probes such as the Bently Nevada 330500) and casing absolute velocity (measured by the 190501-22-00-CN). The 3500 rack architecture natively supports mixed-sensor configurations within the same rack, with the 3500/42M monitor accepting both proximitor and seismic inputs on separate channel pairs. This dual-path redundancy provides complementary diagnostic perspectives and satisfies the voting logic requirements of safety instrumented systems (SIS) designed to IEC 61511 standards.
