Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-01-00-CN Velomitor CT Velocity Transducer delivers precise, reliable measurements. This industrial-grade sensor converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it provides accurate data for condition monitoring systems.
Technical Specifications Breakdown
The 190501-01-00-CN offers a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, covering most rotating machinery vibration frequencies. Its amplitude linearity remains within ±2% up to 63.5 mm/s pk (2.5 in/s pk), ensuring consistent performance across the measurement range. The output bias voltage is 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), simplifying integration with standard data acquisition systems. A mounted resonant frequency of 9 kHz minimum (stud mounted) prevents structural interference.
Industry Applications
This transducer excels in critical rotating equipment such as turbines, compressors, and pumps. In a refinery, for example, the 190501-01-00-CN monitors centrifugal compressor vibration, alerting operators to developing faults before catastrophic failure occurs. Its wide operating temperature range of -40°C to +85°C (-40°F to +185°F) suits outdoor and process plant environments. The 316L stainless steel case and MIL-C-5015 connector withstand corrosive atmospheres.
Installation & Setup Guidance
Mount the transducer using the 3/8-24 stud with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Any mounting angle is acceptable, but ensure the mounting surface is clean and flat (33 mm diameter / 1.3 in diameter). Use Bently Nevada cable part number 02173006 for lengths up to 305 metres (1,000 ft.) without signal degradation. Polarity: Pin A goes positive with respect to Pin B when velocity is from base to top.
Maintenance & Reliability
The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk and 100% condensing humidity tolerance (non-submerged), this transducer withstands harsh industrial conditions. Periodic inspection of cable integrity and connector cleanliness is recommended. The low base strain sensitivity (0.43 mm/s/μstrain) minimizes false readings from structural flexing.
Compatibility & Integration
This velocity transducer connects directly to Bently Nevada monitoring systems and most PLC/DCS analog input modules. The dynamic output impedance is less than 400 Ω typical, allowing easy interfacing. For intrinsically safe installations (Ex ia IIC T4), follow drawing 167536. The 190501-01-00-CN is a drop-in replacement for existing Velomitor CT models.
Selection Guide & Purchasing Advice
Before ordering, verify your mounting hardware and connection requirements. The 190501-01-00-CN includes a 3/8-24 stud and MIL-C-5015 connector. For agency approval, this variant is country-specific (CN). SpareTechPLC stocks this exact model, ensuring fast delivery and genuine Bently Nevada quality.
