Product Details

190501-14-99-CN Product Description

The Bently Nevada 190501-14-99-CN is a Velomitor CT piezo-velocity transducer engineered for direct integration into the Bently Nevada 3500 Series machinery protection architecture. Designed to deliver high-fidelity velocity signals across a broad frequency range, this sensor serves as a critical node in the vibration monitoring layer of rotating equipment protection systems. Its compact, hermetically sealed construction and integral cable assembly make it suitable for demanding industrial environments including power generation turbines, petrochemical compressors, marine propulsion shafts, and mining mill drives. Every unit ships pre-shipment tested and is backed by a 12-Month Warranty, ensuring operational confidence from day one of installation.

The 190501-14-99-CN Velomitor CT is not a standalone device — it is a precision signal source within a layered automation architecture. In a typical 3500 Series machinery protection system, the sensor feeds its velocity signal directly into the Bently Nevada 3500/42M Velocity Monitor module, which processes the analog input and compares it against configurable alert and danger setpoints. The 3500/42M resides in a Bently Nevada 3500 Rack alongside complementary modules such as the 3500/22M Transient Data Interface, the 3500/15 Power Supply, and the 3500/32 4-Channel Relay Module, forming a fully integrated protection chassis.

At the communication layer, the 3500 rack interfaces with plant-level SCADA and DCS platforms via the 3500/92 Communication Gateway, supporting Modbus/TCP and OPC-DA/UA protocols. This enables the velocity data captured by the 190501-14-99-CN to be transmitted in real time to historian servers and operator workstations running System 1 Evolution software, where trend analysis, alarm management, and predictive maintenance workflows are executed. For facilities operating redundant control architectures, the 3500 rack supports dual-redundant power supply configurations using paired 3500/15 Power Supply modules, ensuring uninterrupted monitoring even during a single-point power failure.

On the field wiring side, the 190501-14-99-CN integrates cleanly with Bently Nevada 3500 I/O Modules and terminal block assemblies, minimizing signal conditioning requirements. In applications where the velocity signal must be shared across multiple monitoring systems — for example, a parallel vibration analyzer and the 3500 rack — a signal splitter or passive signal conditioner can be inserted without degrading measurement accuracy, given the sensor's low-impedance ICP® output. For installations requiring intrinsic safety in Zone 1 or Zone 2 hazardous areas, the sensor pairs with approved Zener barrier or galvanic isolator modules mounted in the marshalling cabinet.

In broader plant automation contexts, the velocity data from this sensor contributes to the Asset Performance Management (APM) layer, feeding condition indicators into platforms such as GE APM or Emerson AMS Device Manager. When combined with proximity probe signals from Bently Nevada 3300 XL 8mm Proximity Transducer systems monitoring shaft displacement, and temperature inputs from RTD or thermocouple modules in the 3500/60 Temperature Monitor, operators gain a comprehensive, multi-parameter view of rotating machine health — all traceable back to the 190501-14-99-CN as the velocity sensing element.

Power Generation: In gas turbine and steam turbine installations, the 190501-14-99-CN is mounted on bearing pedestals to monitor casing vibration velocity. The 3500/42M processes the signal and triggers relay outputs to the turbine control system — typically a GE Mark VIe or Emerson Ovation DCS — when velocity exceeds danger thresholds, initiating an automatic trip sequence. This contextual integration between the vibration protection layer and the turbine control layer is essential for safe, unattended operation.

Petrochemical and Oil & Gas: Centrifugal compressors and reciprocating pumps in refinery service demand continuous vibration surveillance. The 190501-14-99-CN's hermetically sealed housing withstands hydrocarbon-laden atmospheres, and its wide temperature range accommodates both ambient and elevated-temperature bearing housings. Integration with the plant DCS via the 3500/92 gateway allows vibration alarms to be annunciated on the operator HMI alongside process variables such as suction pressure and discharge temperature, enabling root-cause correlation.

Water Treatment and Mining: Large-frame pumps, agitators, and ball mill drives in water treatment and mining facilities benefit from the sensor's robust construction and broad frequency response. In these applications, the 3500 rack is often installed in a remote equipment room, with the 190501-14-99-CN cabled back over distances up to 100 meters using the integral armored cable assembly. The System 1 software platform aggregates velocity trends across multiple machines, supporting scheduled maintenance planning and reducing unplanned downtime.

Marine Propulsion: Shipboard propulsion shafts and auxiliary machinery require vibration monitoring that tolerates high ambient vibration, salt-laden air, and wide temperature swings. The 190501-14-99-CN's IP67 rating and hermetic seal make it suitable for engine room installations, where it feeds the 3500 rack mounted in a vibration-isolated control panel. Classification society requirements for continuous machinery monitoring are met through the combination of the sensor, the 3500/42M monitor, and the 3500/32 relay module driving alarm panels.

Q1: Is the 190501-14-99-CN directly compatible with the Bently Nevada 3500/42M Velocity Monitor without additional signal conditioning? Yes. The 190501-14-99-CN outputs an ICP®-compatible voltage signal that is natively accepted by the 3500/42M Velocity Monitor module. The 3500/42M provides the required constant-current excitation (typically 4 mA) through the monitor input circuit, eliminating the need for an external signal conditioner. Verify that the 3500/42M is configured for the correct sensitivity (100 mV/(in/s)) in the rack configuration software before commissioning.

Q2: Can this sensor be used in a redundant monitoring architecture, and how does it integrate with the 3500 rack's redundancy features? The 190501-14-99-CN can be deployed in a dual-sensor redundant configuration by mounting two sensors at 90° intervals on the same bearing housing and connecting each to a separate 3500/42M channel. The 3500 rack supports voted logic through the 3500/32 relay module, allowing the protection system to remain active even if one sensor or channel fails. For power supply redundancy, dual 3500/15 Power Supply modules in the same rack provide automatic failover, ensuring continuous monitoring without interruption.

Q3: What is the long-term maintenance and supply assurance strategy for the 190501-14-99-CN? NANKMOS maintains in-stock inventory of the 190501-14-99-CN to support both planned replacement cycles and emergency procurement. Each unit undergoes pre-shipment functional testing against Bently Nevada factory specifications and is covered by a 12-Month Warranty from the date of shipment. For long-term maintenance planning, we recommend establishing a spare-parts inventory of at least one sensor per critical machine train, aligned with your site's planned maintenance intervals. Our technical team can assist with cross-referencing legacy part numbers and confirming compatibility with existing 3500 rack configurations.
