Product Details

190501-20-00-CN Product Description

The Bently Nevada 190501-20-00-CN Velomitor CT Velocity Transducer is engineered for continuous vibration velocity measurement in rotating machinery environments. Delivering a wide-band analog output signal, this transducer serves as a critical front-end sensing node in the industrial data chain — capturing real-time mechanical vibration data from pumps, compressors, turbines, fans, and motors, and feeding that signal upstream into PLC controllers, remote I/O modules, SCADA platforms, and HMI visualization systems.

In modern smart factory deployments, the 190501-20-00-CN functions as the origin point of a complete data flow architecture. Its analog 4–20 mA or voltage output integrates directly with Bently Nevada 3500 Series rack-based monitoring systems, where signal conditioning modules convert raw velocity data into structured process values. From there, the conditioned data travels via Modbus RTU or Modbus TCP/IP to distributed control systems (DCS) or SCADA servers, enabling plant-wide vibration trend analysis, alarm management, and predictive maintenance scheduling.

The 190501-20-00-CN Velomitor CT sits at the sensor layer of a multi-tier industrial network. In a typical smart factory deployment, the transducer is mounted on a rotating machine casing and wired back to a Bently Nevada 3500/42M Proximitor/Seismic Monitor module housed in a 3500 Series rack. The rack's communication gateway card — such as the Bently Nevada 3500/92 Communication Gateway — bridges the analog monitoring data to Ethernet-based plant networks using Modbus TCP/IP or OPC-DA protocols.

At the network layer, an industrial managed Ethernet switch (such as those from the Hirschmann MACH or Moxa EDS series) aggregates data streams from multiple 3500 racks, remote I/O panels, and field instruments onto a redundant ring topology. This ensures that vibration data from the 190501-20-00-CN reaches the SCADA server without packet loss or latency spikes — critical for alarm-triggered shutdown logic in turbine protection systems.

For sites integrating legacy PROFIBUS DP field devices alongside the Bently Nevada platform, a PROFIBUS-to-Modbus gateway (such as the HMS Anybus X-gateway or Moxa MGate series) enables seamless protocol translation, allowing the velocity transducer's data to coexist with signals from Siemens S7-300/S7-400 PLCs or ABB AC500 controllers on the same SCADA backbone. The unified data stream is then visualized on Wonderware InTouch or Ignition SCADA HMI screens, where operators monitor velocity trend curves, set alarm thresholds, and configure automatic shutdown triggers.

At the edge layer, an industrial edge gateway — such as the Advantech WISE-5000 or Siemens SINEMA Remote Connect — can aggregate OPC-UA data from the 3500 rack and push it to cloud-based condition monitoring platforms or MES systems. This enables remote diagnostics of the 190501-20-00-CN's host machine from any location, with vibration waveform data available for FFT analysis and bearing fault detection without requiring on-site personnel.

Power for the transducer and associated signal conditioning is typically supplied by a 24 VDC industrial DIN-rail power supply (such as Phoenix Contact QUINT or MEAN WELL DR series), ensuring stable, noise-filtered excitation voltage that preserves signal integrity across long cable runs in electrically noisy plant environments.

Many industrial facilities face persistent challenges with protocol fragmentation — where vibration sensors output analog signals that cannot be directly consumed by modern Ethernet-based SCADA or MES platforms. The 190501-20-00-CN addresses this by delivering a clean, high-fidelity analog velocity signal that is universally compatible with any signal conditioning module or analog input card, regardless of the upstream PLC or DCS brand.

Data island elimination is another key value. In plants where vibration data was historically siloed in standalone condition monitoring recorders, integrating the 190501-20-00-CN into a Bently Nevada 3500 rack with a communication gateway card breaks down those silos — making machine health data available to SCADA historians, ERP maintenance modules, and cloud analytics platforms simultaneously.

For remote monitoring and diagnostics, the transducer's continuous analog output enables 24/7 unattended surveillance of critical rotating assets. When velocity amplitude exceeds a configured alarm setpoint in the 3500 rack, the system can trigger automated alerts via SCADA alarm management, send SMS/email notifications through the plant's DCS, and log the event with a precise timestamp for root-cause analysis — all without manual intervention.

Production line transparency is enhanced by trending the 190501-20-00-CN's output over time. Operators can identify gradual bearing wear, misalignment, or imbalance weeks before failure, enabling planned maintenance windows that avoid unscheduled downtime. System scalability is straightforward: additional Velomitor CT transducers can be added to the 3500 rack's available monitor slots, expanding coverage to additional machine trains without changes to the SCADA or network infrastructure.

Q1: What communication protocols does the Bently Nevada 190501-20-00-CN support for SCADA integration? The 190501-20-00-CN outputs an analog velocity signal. When connected to a Bently Nevada 3500 Series rack with a 3500/92 Communication Gateway, the system supports Modbus RTU, Modbus TCP/IP, and OPC-DA/OPC-UA protocols, enabling direct integration with SCADA platforms such as Ignition, Wonderware, and FactoryTalk. For PROFIBUS or DeviceNet environments, a protocol gateway module is required.

Q2: How is network stability and data latency managed in high-vibration plant environments? The 190501-20-00-CN's analog output is inherently immune to network latency — the signal is continuous and real-time at the sensor level. Network latency only applies at the Modbus/OPC communication layer between the 3500 rack and the SCADA server. Using a managed industrial Ethernet switch with QoS prioritization and redundant ring topology (IEC 62439-3 / MRP) ensures sub-10ms failover and consistent data delivery to the historian.

Q3: Can the 190501-20-00-CN be integrated into an existing Siemens or Rockwell PLC-based control system? Yes. The transducer's analog output connects to any standard analog input module — including Siemens ET 200SP, Rockwell Allen-Bradley 1734 POINT I/O, or Beckhoff EL3xxx series terminals. The conditioned signal is then processed by the PLC and made available to the SCADA layer via PROFINET, EtherNet/IP, or Modbus TCP/IP, depending on the controller platform.

Q4: What does the 12-month warranty cover, and is pre-shipment testing performed? Every 190501-20-00-CN unit supplied by NANKMOS undergoes pre-shipment functional verification, including output signal integrity checks and connector inspection. The 12-month warranty covers manufacturing defects and functional failures under normal operating conditions. Units are shipped with original packaging and, where available, factory calibration documentation. For warranty claims or technical support, contact [email protected].
