Product Introduction
When machinery vibration threatens uptime, the Bently Nevada 190501-11-00-04 Velomitor CT Velocity Transducer delivers precise, reliable measurement. This industrial automation module is engineered for permanent installation on rotating equipment, providing continuous velocity data to protect your assets. Manufactured in the U.S.A., the 190501-11-00-04 is a key component in predictive maintenance strategies.
Technical Specifications Breakdown
The Bently Nevada 190501-11-00-04 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This broad bandwidth captures both low-speed and high-speed machinery vibrations.
Temperature sensitivity of -8% to +5% typical over the operating temperature range (-40°C to +85°C) maintains stability in harsh environments. The transducer handles shock limits up to 5000 g pk and operates in 100% condensing humidity. With a mounted resonant frequency of 9 kHz minimum (stud mounted), the 190501-11-00-04 resists false readings from structural resonance.
Industry Applications
The Bently Nevada 190501-11-00-04 excels in critical rotating machinery monitoring. Typical applications include:
- Pumps and compressors in oil & gas facilities
- Turbines and generators in power plants
- Paper mill rollers and pulp processing equipment
- Cooling tower fans and HVAC systems
In each scenario, the high sensitivity and robust construction deliver dependable data for condition monitoring, helping you avoid unplanned downtime.
Installation & Setup Guidance
Proper mounting is crucial for accurate readings. The 190501-11-00-04 includes a plate stud (3/8-in 24 to 1/4-in 28) for secure attachment. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the mounting surface is flat and clean—a 33 mm diameter (1.3 in) area is required. The transducer can be mounted in any orientation, but verify that the cable routing avoids sharp bends and excessive strain.
For electrical connections, use the 2-pin 316L stainless steel MIL-C5015 connector. The output bias voltage is 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B). Observe polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 with no signal degradation.
Maintenance & Reliability
Routine inspection of the mounting integrity and cable condition ensures long-term reliability. The 316L stainless steel case resists corrosion, and internal electronics are isolated from the case, reducing ground loop issues. Base strain sensitivity is only 0.43 mm/s/μstrain, minimizing false signals from mounting stress. With proper care, this transducer delivers years of dependable service.
Compatibility & Integration
The 190501-11-00-04 integrates seamlessly with Bently Nevada monitoring systems and other vibration data collectors. Its dynamic output impedance of <400 Ω typical allows direct connection to most PLC/DCS analog input modules. The agency approvals include CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1), making it suitable for hazardous areas.
Selection Guide & Purchasing Advice
Before ordering, verify your required agency approval option and mounting hardware. The 190501-11-00-04 configuration includes option 11 (plate stud) and connection option 00 (MIL-C-5015). For hazardous locations, confirm the intrinsic safety rating matches your zone classification. PLC Source PRO offers genuine Bently Nevada parts with fast worldwide shipping.
