Product Details

190501-23-00-CN Product Description

The Bently Nevada 190501-23-00-CN is a Velomitor CT piezoelectric velocity transducer engineered for seamless integration within multi-layer industrial control architectures. Designed to deliver high-fidelity vibration velocity signals across demanding operational environments, this transducer serves as a critical sensing node within the 3500 Series machinery protection platform — enabling real-time condition monitoring, predictive maintenance, and system-wide diagnostic coherence. Its role extends far beyond simple signal generation: it anchors the measurement layer of a complete automation hierarchy, ensuring that every upstream decision — from relay trip logic to HMI alarm visualization — is grounded in accurate, low-noise velocity data.

Within a fully realized industrial automation architecture, the 190501-23-00-CN operates as the front-end sensing element of a layered machinery protection system. Its velocity output feeds directly into the Bently Nevada 3500/42M Proximitor/Seismic Monitor module, which processes the signal and compares it against configurable alert and danger setpoints. The 3500/42M resides within the Bently Nevada 3500 Rack — a modular backplane system that consolidates multiple channel types, including proximity probes, accelerometers, and process variables, into a unified monitoring chassis.

At the power layer, the Bently Nevada 3500/15 Power Supply module provides regulated, redundant DC power to all rack-mounted cards, ensuring that transducer excitation and signal conditioning remain stable even during grid fluctuations. For facilities requiring dual-redundant power architectures, a secondary 3500/15 can be hot-swapped without interrupting monitoring continuity — a critical feature in continuous-process industries such as petrochemical refining and power generation.

Signal integrity from the 190501-23-00-CN is further protected by Bently Nevada 3500/20 Rack Interface Module, which manages communication between the monitoring rack and plant-level control systems via Modbus TCP or OPC-DA/UA protocols. This enables the 3500 platform to transmit real-time vibration velocity data to a GE Mark VIe or Emerson DeltaV DCS, where the data is contextualized alongside process variables such as bearing temperature, lube oil pressure, and shaft speed — forming the basis of a holistic machine health dashboard.

At the HMI layer, operators interact with aggregated machinery data through Bently Nevada System 1 condition monitoring software, which ingests velocity trend data from the 190501-23-00-CN and correlates it with historical baselines to generate predictive maintenance alerts. Integration with Rockwell Automation FactoryTalk View or Siemens WinCC SCADA platforms is achievable via OPC bridging, enabling cross-platform alarm annunciation without duplicating sensor infrastructure.

For installations requiring signal isolation — particularly in environments with high electromagnetic interference from variable frequency drives or large motor starters — a Phoenix Contact MACX MCR signal isolator can be inserted between the transducer cable and the rack input terminal, preserving signal fidelity across long cable runs. Terminal connections are managed through Bently Nevada 3500 I/O Module field wiring termination assemblies, which support both armored and standard instrumentation cables.

In redundant protection architectures, the 190501-23-00-CN is often deployed in paired configurations — one transducer mounted radially and one axially — feeding separate channels within the 3500/42M to provide 2-out-of-2 (2oo2) or 2-out-of-3 (2oo3) voting logic for trip relay activation. The trip output from the Bently Nevada 3500/32 Relay Module is then wired to the machine's emergency shutdown (ESD) system, completing the protective loop from field sensor to final element.

The 190501-23-00-CN finds application across a broad spectrum of rotating machinery protection scenarios. In power generation facilities, it monitors steam turbine bearing housings, providing early warning of imbalance, misalignment, and bearing degradation before catastrophic failure occurs. In petrochemical and refinery environments, it is mounted on centrifugal compressors and boiler feed pumps — machines whose unplanned downtime carries significant safety and financial consequences.

In water treatment and municipal utility plants, the transducer supports continuous monitoring of large vertical pump motors, where vibration trending enables maintenance teams to schedule bearing replacements during planned outages rather than responding to emergency failures. In mining and mineral processing operations, it is deployed on ball mills, crushers, and conveyor drive gearboxes — environments characterized by high shock loads and variable operating speeds that demand robust, wide-bandwidth velocity sensing.

For marine and offshore applications, the IP67-rated housing and wide operating temperature range of the 190501-23-00-CN make it suitable for shipboard propulsion monitoring and offshore platform compressor protection. In packaging and discrete manufacturing lines, it supports predictive maintenance programs on high-speed rotary equipment, reducing unplanned downtime and extending mean time between failures (MTBF) across the production floor.

Q1: Is the 190501-23-00-CN directly compatible with the Bently Nevada 3500 Series rack without additional signal conditioning? Yes. The 190501-23-00-CN is designed for direct integration with the 3500/42M Proximitor/Seismic Monitor module. The transducer's output signal characteristics are matched to the input specifications of the 3500 rack, eliminating the need for external signal conditioning in standard installations. For long cable runs exceeding 300 meters or installations near high-EMI sources, a signal isolator is recommended to maintain measurement accuracy.

Q2: Can this transducer be used in a redundant monitoring architecture, and how does it interact with the trip relay logic? Absolutely. The 190501-23-00-CN supports redundant deployment configurations. When paired with a second transducer on the same machine, both channels feed into separate 3500/42M inputs, enabling voting logic (1oo2, 2oo2, or 2oo3) to be configured within the rack. Trip outputs from the 3500/32 Relay Module are then wired to the ESD or safety instrumented system (SIS), ensuring that a single transducer fault does not cause a spurious trip while maintaining full protective coverage.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for in-stock units? All 190501-23-00-CN units supplied by NANKMOS are covered by a 12-Month Warranty against manufacturing defects and functional failure under normal operating conditions. Each unit undergoes pre-shipment functional testing to verify output signal integrity, frequency response, and connector continuity before dispatch. In-stock units are typically available for same-week shipment.
