Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-12-00-CN Velomitor CT Velocity Transducer delivers precise, reliable measurements. This rugged sensor converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. Designed for continuous duty in harsh environments, it helps maintenance engineers prevent catastrophic failures and reduce unplanned downtime.
Key Technical Specifications
The 190501-12-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration amplitude readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, covering most rotating machinery speeds. The transducer operates from -40°C to +85°C (-40°F to +185°F) and withstands up to 5000 g pk shock, making it suitable for demanding industrial settings. Output bias voltage is 10.1 Vdc ± 1.0 Vdc, with a dynamic output impedance less than 400 Ω typical.
Industry Applications
This velocity transducer excels in monitoring pumps, compressors, fans, and turbines. In a petrochemical plant, for instance, it continuously tracks vibration on critical centrifugal compressors, alerting operators to developing faults before they cause unplanned shutdowns. Its 316L stainless steel case and 100% condensing humidity tolerance ensure reliable operation in wet or corrosive environments.
Installation & Setup Guidance
Mount the transducer using the included 3/8-in 24 to M8x1 stud plate. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The unit can be oriented at any angle, simplifying placement. Connect via the MIL-C-5015 2-pin connector; ensure Pin A is referenced to Pin B for correct polarity. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation.
Maintenance & Reliability
Routine inspection of the transducer and its cable is recommended to verify secure mounting and connector integrity. The internal electronics are isolated from the case, reducing ground loop issues. With a mounted resonant frequency of 9 kHz minimum, the sensor resists resonance-related errors. Its robust design minimizes maintenance needs, contributing to lower total cost of ownership.
Compatibility & Integration
The 190501-12-00-CN integrates seamlessly with Bently Nevada monitoring systems and most industrial vibration data collectors. Its standard sensitivity and output bias voltage allow direct connection to compatible PLCs and DCS modules. For intrinsically safe installations, refer to drawing 167536 and verify agency approval options (Ex ia IIC T4 or Ex nL IIC T4).
Selection Guide & Purchasing Advice
Before ordering, confirm your application requires a velocity transducer with 3.94 mV/mm/s sensitivity and the specified frequency response. Verify mounting hardware compatibility (plate stud 3/8-in 24 to M8x1) and connection type (MIL-C-5015). SpareTechPLC stocks the 190501-12-00-CN and can advise on availability and replacement options.
