Product Overview
When unplanned machinery downtime threatens production targets, the Bently Nevada 190501-11-00-CN Velomitor CT Velocity Transducer provides the precise vibration data needed for predictive maintenance. This rugged sensor converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment in rotating equipment.
Technical Specifications Breakdown
The 190501-11-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate measurement across its operating range. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, and extends from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. This wide bandwidth captures both low-speed and high-speed machinery vibrations effectively.
Amplitude linearity holds within ±2% up to 63.5 mm/s pk (2.5 in/s pk), providing reliable readings under varying load conditions. The mounted resonant frequency exceeds 9 kHz minimum, minimizing interference from structural resonances. Output bias voltage sits at 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), with a dynamic output impedance below 400 Ω typical.
Industry Applications
In petrochemical plants, the 190501-11-00-CN monitors critical pumps and compressors operating in harsh environments. Its 316L stainless steel case and 100% condensing humidity tolerance make it suitable for wash-down areas and outdoor installations. For power generation facilities, the transducer's 5000 g pk shock limit withstands sudden load changes and transient events without damage.
Installation & Setup Guidance
Mount the transducer using the provided 3/8-in 24 to 1/4-in 28 plate stud with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The MIL-C-5015 connection interface ensures a secure, weatherproof electrical connection. Orientation can be any angle, simplifying installation in tight spaces. Maximum cable length reaches 305 metres (1,000 ft.) using cable part number 02173006 without signal degradation.
Maintenance & Reliability
The internal electronics are isolated from the case, reducing ground loop issues and improving signal integrity. Routine inspection should focus on cable integrity and connector tightness. With an operating temperature range of -40°C to +85°C (-40°F to +185°F) and storage capability from -40°C to +100°C (-40°F to +212°F), this transducer performs reliably in extreme climates. The 316L stainless steel construction resists corrosion, extending service life in aggressive environments.
Compatibility & Integration
This velocity transducer integrates seamlessly with Bently Nevada monitoring systems and most industrial vibration data collectors. The dynamic output signal is compatible with standard PLC and DCS analog input modules. For intrinsically safe installations, the 190501-11-00-CN carries Ex ia IIC T4 and Class I, Division 1 approvals for hazardous areas.
Buying Guide
Before purchasing, verify that your monitoring system accepts a velocity input with 3.94 mV/mm/s sensitivity. Confirm the mounting thread requirement matches the 3/8-in 24 to 1/4-in 28 stud. SpareTechPLC stocks the Bently Nevada 190501-11-00-CN with fast shipping and expert support to ensure you get the right sensor for your application.
