Product Details

190501-00-00-CN Product Description

The Bently Nevada 190501-00-00-CN is a Velomitor CT piezoelectric velocity transducer engineered for seamless integration into the Bently Nevada 3500 Series machinery protection and condition monitoring platform. Designed to deliver high-fidelity vibration velocity signals across a broad frequency range, this transducer serves as a critical sensing node within layered industrial control architectures — connecting the physical machine layer to the protection, diagnostic, and supervisory control layers above it.

In modern industrial automation environments, a velocity transducer is never a standalone device. The 190501-00-00-CN is purpose-built to operate within a coherent system architecture where signal integrity, module compatibility, and long-term reliability are non-negotiable. Whether deployed in rotating machinery protection for turbines, compressors, pumps, or motors, this transducer provides the foundational vibration data that drives real-time protection decisions, predictive maintenance workflows, and plant-wide asset health monitoring.

The 190501-00-00-CN Velomitor CT transducer achieves its full operational value when deployed as part of a complete Bently Nevada 3500 Series machinery protection architecture. At the monitoring layer, the transducer feeds analog velocity signals directly into the Bently Nevada 3500/42M Proximitor/Seismic Monitor or the 3500/40M Proximitor Monitor, which perform real-time signal conditioning, alarm setpoint evaluation, and relay output actuation. These monitor modules reside in the 3500 Series Rack — a modular backplane chassis that supports up to 16 monitor cards and provides the structural backbone for the entire protection system.

System power integrity is maintained by the Bently Nevada 3500/15 Power Supply Module, which delivers regulated DC power to all rack-mounted modules and supports redundant power input configurations for critical applications. For communication and data acquisition, the 3500/22M Transient Data Interface (TDI) module captures high-resolution waveform data from the 190501-00-00-CN and transmits it upstream to plant historians and condition monitoring software via Ethernet or serial protocols.

At the supervisory control layer, the 3500 rack integrates with Bently Nevada System 1 condition monitoring software, enabling trend analysis, spectrum plots, and predictive maintenance scheduling based on the velocity data sourced from the 190501-00-00-CN. For plants operating on a DCS or PLC backbone, the 3500/92 Communication Gateway Module bridges the 3500 rack to Modbus, Profibus, or OPC-UA networks, allowing the velocity transducer's data to flow into broader control architectures built on platforms such as the GE Mark VIe or Emerson DeltaV.

In multi-machine protection schemes, the 190501-00-00-CN is often deployed alongside Bently Nevada 330103 Proximity Probes for shaft relative vibration measurement and 3300 XL 8mm Proximity Transducer Systems for radial and axial position monitoring. This combination of casing velocity (from the Velomitor CT) and shaft proximity data provides a complete vibration picture — both absolute and relative motion — essential for API 670-compliant machinery protection on critical rotating equipment. Cable assemblies such as the Bently Nevada 330130 Extension Cable and 330180 Proximitor Sensor complete the signal chain from machine to monitor rack.

Power Generation & Turbomachinery: In gas turbine and steam turbine protection systems, the 190501-00-00-CN monitors casing vibration on bearing housings, providing early warning of imbalance, misalignment, and bearing degradation. Integrated with the 3500/42M monitor and System 1 software, it supports continuous online protection for critical generation assets where unplanned downtime carries severe operational and financial consequences.

Petrochemical & Refinery Compressor Trains: Centrifugal and reciprocating compressor trains in petrochemical plants require multi-point vibration monitoring across multiple bearing locations. The 190501-00-00-CN is deployed at casing measurement points while proximity probes monitor shaft motion, together feeding the 3500 rack with a complete vibration dataset. This dual-sensor architecture satisfies API 670 requirements for compressor protection in hazardous area installations.

Water Treatment & Pump Stations: Large centrifugal pumps in water treatment and distribution infrastructure benefit from casing-mounted velocity transducers for continuous health monitoring. The 190501-00-00-CN's wide temperature range and robust stainless steel housing make it suitable for outdoor and semi-exposed pump station environments, where it provides reliable vibration data to local or remote monitoring systems.

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. The 190501-00-00-CN's rugged construction and broad frequency response make it well-suited for casing vibration monitoring on these high-power rotating assets, supporting predictive maintenance programs that reduce unplanned shutdowns in continuous process mining operations.

Marine & Offshore Propulsion Systems: Shipboard propulsion machinery, auxiliary generators, and pump systems on offshore platforms require vibration monitoring solutions that meet marine classification standards. The 190501-00-00-CN's compact form factor and stainless steel housing support installation in confined machinery spaces, providing reliable velocity data for onboard condition monitoring systems.

Q1: Is the Bently Nevada 190501-00-00-CN compatible with the full 3500 Series rack system, and which monitor modules does it interface with? Yes. The 190501-00-00-CN Velomitor CT is designed for direct integration with the Bently Nevada 3500 Series Machinery Protection System. It interfaces primarily with the 3500/42M Proximitor/Seismic Monitor and the 3500/40M Proximitor Monitor, which accept analog velocity signals from the transducer and perform alarm evaluation, relay actuation, and data output. The transducer is also compatible with the 3500/45 Position Monitor in seismic velocity measurement configurations. All modules reside in the standard 3500 Series rack chassis, ensuring a fully integrated, API 670-compliant protection architecture.

Q2: Can the 190501-00-00-CN be used in hazardous area installations, and what installation considerations apply? The 190501-00-00-CN is engineered for industrial environments and is suitable for use in many hazardous area classifications when installed with appropriate certified barriers, conduit seals, and cable assemblies per local electrical codes and IEC/NEC hazardous area requirements. For ATEX or IECEx-rated installations, consult the Bently Nevada installation manual and verify that all associated equipment in the signal chain — including extension cables, junction boxes, and monitor modules — carries the required certifications. Proper grounding, cable shielding, and conduit sealing are essential to maintain signal integrity and system safety in classified areas.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for in-stock units? All 190501-00-00-CN units supplied by NANKMOS are covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. The warranty covers the transducer assembly, connector, and cable exit — ensuring that the unit performs to published specifications for the duration of the warranty period. In-stock units are available for shipment within 1–3 business days following order confirmation. Each unit undergoes pre-shipment functional testing to verify output sensitivity, frequency response, and connector integrity before dispatch.
