Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-01-00-01 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. Designed for harsh environments, it features a 316L stainless steel case and intrinsic safety certifications for hazardous locations.
Technical Specifications Breakdown
The 190501-01-00-01 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration readings across a wide frequency range. 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. The output bias voltage sits at 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. With a mounted resonant frequency of 9 kHz minimum (stud mounted), this transducer avoids resonance interference in most industrial applications.
Industry Applications
In petrochemical plants, the 190501-01-00-01 monitors critical rotating equipment like pumps and compressors. Its intrinsic safety approvals (Ex ia IIC T4) allow installation in Class I, Division 1 hazardous areas. For power generation, the transducer provides reliable vibration data on turbines and generators, helping prevent catastrophic failures. The wide operating temperature range of -40°C to +85°C suits both indoor and outdoor installations.
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). The MIL-C-5015 connector ensures a secure, weatherproof connection. Any mounting orientation is acceptable. For optimal signal integrity, use cable part number 02173006 up to 305 metres (1,000 ft.) without degradation. Ground the system per drawing 167536 to maintain intrinsic safety.
Maintenance & Reliability
The 190501-01-00-01 requires minimal maintenance due to its robust design. Internal electronics are isolated from the case, reducing ground loop issues. The 316L stainless steel construction resists corrosion in humid or chemical environments. Periodic inspection of the connector and cable for damage ensures long-term reliability. With a shock limit of 5000 g pk, the transducer withstands severe mechanical shocks.
Compatibility & Integration
This velocity transducer integrates seamlessly with Bently Nevada monitoring systems. The 2-pin MIL-C-5015 connector provides a standard interface. Use the specified cable (02173006) for maximum performance. The transducer's dynamic output impedance of less than 400 Ω typical allows easy connection to data acquisition modules.
Selection Guide & Purchasing Advice
Before ordering, verify the agency approval option (190501-01-00-01 includes CSA/NRTL/C, ATEX/IECEx/CSA Class I, Division 1, Zone 0/1). Confirm mounting hardware compatibility with your installation. SpareTechPLC stocks the 190501-01-00-01 and can advise on availability and replacement options. Please verify current lifecycle status before ordering.
