Products Description
Bently Nevada 190501-12-00-04 Velomitor CT Velocity Transducer
The Bently Nevada 190501-12-00-04 Velomitor CT Velocity Transducer is a field-mounted vibration measurement device developed for continuous monitoring of casing vibration on rotating machinery. It combines a velocity sensing element with internal signal conditioning electronics, delivering a standardized current output suitable for direct connection to monitoring and control systems.
By integrating sensing and transmission functions into a single compact housing, the transducer simplifies vibration measurement architectures while maintaining measurement stability. It is designed to operate reliably in industrial environments where long-term vibration data is required for machinery protection and condition-based maintenance.
With over 50 million in inventory, PLC EXPORT delivers only brand-new, authentic components- ready to ship,
rigorously tested, and backed by professional technical support.

Functional Role / System Position
Within a machinery monitoring system, the Velomitor CT operates at the field instrumentation level. It converts mechanical vibration from the machine casing into an electrical signal proportional to vibration velocity and transmits this signal to monitoring racks, protection systems, or distributed control platforms.
The transducer functions purely as a measurement and signal interface device. It does not perform control logic or data processing, but instead provides reliable raw velocity data to upstream systems responsible for analysis, alarming, and shutdown decisions.
Key Features / Functional Capabilities
- Integrated velocity sensor and current transmitter in a single housing
- Direct measurement of absolute casing vibration velocity
- 4–20 mA output suitable for long-distance signal transmission
- Stable sensitivity for continuous monitoring applications
- Internal signal conditioning without external modules
- Designed for permanent installation on industrial machinery
Application Areas / Typical Use Cases
The 190501-12-00-04 is commonly applied to general rotating equipment such as pumps, motors, fans, and compressors. It is widely used in balance-of-plant monitoring systems where casing vibration is the primary diagnostic parameter rather than shaft-relative motion.
Typical installations include auxiliary equipment in power generation facilities, industrial process plants, and machinery skids where compact, self-contained velocity measurement devices are preferred.

Installation Guidance
The transducer is mounted directly to the machine casing using a threaded stud. The mounting surface should be clean, flat, and rigid to ensure proper mechanical coupling and accurate vibration measurement. Correct installation torque and orientation are important for repeatable results.
Signal wiring should follow standard industrial practices, with appropriate grounding and shielding to maintain signal integrity in electrically noisy environments.
Advantages / Value Highlights
The integrated design reduces system complexity and installation effort by combining sensing and signal conditioning in one device. The standardized current output improves compatibility with both Bently Nevada and third-party monitoring systems. Long-term stability supports reliable vibration trending and early fault detection, contributing to improved machinery availability and reduced maintenance risk.
