Product Details

190501-19-00-CN Product Description

The Bently Nevada 190501-19-00-CN Velomitor CT Velocity Transducer is a precision-engineered sensing component designed to operate as an integral element within the Bently Nevada 3500 Series machinery protection architecture. Rather than functioning as a standalone measurement device, this transducer is purpose-built to deliver consistent, high-fidelity velocity signals across the full control hierarchy — from the field sensing layer through to the control room decision layer — ensuring that every tier of the automation platform receives accurate, time-synchronized vibration data for real-time protection and long-term asset health management.

In a fully realized Bently Nevada machinery protection system, the 190501-19-00-CN does not operate in isolation. Its signal output feeds directly into the 3500/42M Velocity Monitor module, which processes the raw velocity waveform and applies configurable alert and danger setpoints. The 3500/42M resides within the 3500 Rack System — a modular, backplane-based chassis that also accommodates the 3500/15 Power Supply Module, providing stable, conditioned DC power to all installed I/O and processing cards. The rack's internal communication bus ensures that data from the 190501-19-00-CN is available to the 3500/22M Transient Data Interface (TDI) for high-resolution waveform capture during startup, shutdown, and trip events.

At the communication layer, the 3500 rack interfaces with plant-level DCS or SCADA platforms via the 3500/92 Communication Gateway Module, which supports Modbus TCP, OPC-DA, and Ethernet/IP protocols. This enables the velocity data from the 190501-19-00-CN to be consumed by upstream control systems — such as a GE Mark VIe Turbine Control System or a Honeywell Experion PKS DCS — without requiring signal conversion or protocol bridging at the field level. The result is a seamless, low-latency data path from the transducer to the operator HMI.

For HMI visualization, the velocity trend and alarm status generated by the 190501-19-00-CN are typically displayed on a System 1 Evolution Condition Monitoring Software workstation, where engineers can review historical waveform data, configure alarm thresholds, and generate compliance reports. In redundant architectures, a secondary 3500/42M module may be installed in a hot-standby configuration, ensuring that a single card failure does not interrupt machinery protection coverage.

At the power layer, the 3500/15 Power Supply is often paired with a redundant companion unit to eliminate single-point-of-failure risk at the rack level. Field wiring from the 190501-19-00-CN is terminated at the 3500/42M I/O Module Terminal Block, which provides clearly labeled screw terminals for signal, shield, and power conductors. In installations where cable runs exceed recommended lengths, a Bently Nevada Signal Conditioner may be inserted in-line to maintain signal integrity and prevent ground loop interference.

For applications requiring simultaneous velocity and displacement monitoring — common in large steam turbines and compressors — the 190501-19-00-CN is deployed alongside Bently Nevada 3300 XL 8mm Proximity Probes and their associated 3300 XL Proximitor Sensors, providing complementary absolute and relative shaft motion data within the same rack architecture. This multi-parameter approach gives maintenance engineers a complete picture of rotor dynamic behavior without requiring separate monitoring platforms.

Power Generation: In gas turbine and steam turbine installations, the 190501-19-00-CN is mounted on bearing housings to monitor casing vibration during load transitions, startup sequences, and emergency shutdowns. Its wide operating temperature range and IP67 rating make it suitable for outdoor turbine enclosures subject to weather exposure and condensation.

Petrochemical & Refining: Centrifugal compressors and process pumps in refinery environments benefit from continuous velocity monitoring to detect imbalance, misalignment, and bearing degradation before they escalate to unplanned shutdowns. The 190501-19-00-CN's compatibility with the 3500 rack system allows it to be integrated into existing SIL-rated safety instrumented systems without additional interface hardware.

Water & Wastewater Treatment: Large vertical turbine pumps and blower units in water treatment facilities require reliable vibration monitoring to maintain regulatory compliance and prevent catastrophic failures. The 190501-19-00-CN provides the necessary measurement accuracy and environmental durability for these demanding, continuously operating assets.

Mining & Minerals Processing: Ball mills, SAG mills, and conveyor drive systems in mining operations generate complex vibration signatures that require high-bandwidth velocity sensing. The 190501-19-00-CN's 10–1,000 Hz frequency range captures both low-frequency structural resonance and high-frequency bearing defect frequencies within a single measurement channel.

Marine & Offshore: Shipboard propulsion systems and offshore platform compressors operate in high-vibration, high-humidity environments where sensor reliability is critical. The 190501-19-00-CN's rugged construction and sealed connector system ensure long-term measurement stability even in salt-air and wave-motion conditions.

Q1: Is the 190501-19-00-CN directly compatible with the Bently Nevada 3500/42M Velocity Monitor without additional signal conditioning? Yes. The 190501-19-00-CN is designed as a system-matched component for the 3500/42M module. It delivers a conditioned velocity output that meets the input specifications of the 3500/42M without requiring external signal conditioners or impedance matching networks. Standard 2-conductor shielded cable is sufficient for most installation distances within the same control cabinet or local equipment room.

Q2: Can this transducer be used in a redundant monitoring architecture, and how does it affect rack configuration? Yes. In redundant configurations, two 190501-19-00-CN units are mounted at the same measurement point (or at adjacent bearing locations) and wired to separate 3500/42M modules within the same rack or across dual racks. The 3500 rack's internal voting logic can be configured to require agreement between both channels before issuing a trip command, reducing the risk of spurious shutdowns while maintaining full protection coverage. No special firmware or hardware modifications are required beyond standard rack configuration in the System 1 software environment.

Q3: What warranty and supply chain support is available for the 190501-19-00-CN? All 190501-19-00-CN units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing to verify output signal accuracy and connector integrity. NANKMOS maintains stock inventory to support urgent replacement requirements, with expedited shipping available to minimize machinery downtime. For long-term maintenance planning, NANKMOS can provide multi-unit supply agreements to ensure consistent availability across planned maintenance cycles.
