Product Overview
Industrial machinery has evolved from simple rotating equipment to complex, high-speed systems where predictive maintenance is critical. The Bently Nevada 190501-08-00-00 Velomitor CT Velocity Transducer addresses this need by delivering reliable vibration measurement for asset protection. This sensor converts mechanical velocity into a proportional electrical signal, enabling early detection of bearing wear, imbalance, and misalignment.
Technical Specifications Breakdown
The 190501-08-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings across a wide dynamic 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. This makes it suitable for monitoring low-speed to medium-speed rotating machinery. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced Pin A to Pin B, with a dynamic output impedance of less than 400 Ω typical. Amplitude linearity is ±2% to 63.5 mm/s pk (2.5 in/s pk), ensuring consistent performance under varying vibration levels.
Industry Applications
In the oil and gas sector, the 190501-08-00-00 monitors centrifugal pumps and compressors for early signs of failure. Its operating temperature range of -40°C to +85°C (-40°F to +185°F) and 100% condensing humidity tolerance make it ideal for harsh outdoor environments. Power generation plants use this transducer on steam turbines and fans, leveraging its 9 kHz minimum mounted resonant frequency to avoid structural resonance interference. The transducer's 316L stainless steel case and 2-pin MIL-C-5015 connector provide corrosion resistance in chemical processing applications.
Installation & Setup Guidance
Mount the 190501-08-00-00 on a flat, clean surface with a 33 mm diameter (1.3 in diameter) mounting area. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) using a calibrated torque wrench. The transducer accepts any orientation, simplifying placement on vertical or horizontal surfaces. For stud mounting, use the included 3/8-in-24 to 1/2-in-20 plate stud. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation. Ensure Pin A goes positive with respect to Pin B when velocity is from base to top.
Maintenance & Reliability
Routine inspection of the transducer and cable connections helps maintain signal integrity. The internal electronics are isolated from the case, reducing ground loop issues. The shock limit of 5000 g pk protects the sensor during unexpected impacts. Its magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, ensuring stable readings near electrical equipment. Regular calibration checks against the ±5% sensitivity tolerance are recommended.
Compatibility & Integration
The 190501-08-00-00 integrates with Bently Nevada monitoring systems and most industrial vibration data collectors. Its MIL-C-5015 connection option ensures robust, weatherproof connectivity. The transducer's intrinsic safety approvals (Ex ia IIC T4, Class I, Div 1, Groups A-D) allow installation in hazardous areas when wired per drawing 167536. For non-incendive applications, Ex nL IIC T4 and AEx nA T4 approvals apply.
Selection Guide & Purchasing Advice
Before ordering, verify the mounting hardware option (08 plate stud) and connection option (00 MIL-C-5015) match your installation requirements. The agency approval option (00) indicates no approvals; for intrinsically safe versions, select options 01 through 04. SpareTechPLC stocks the Bently Nevada 190501-08-00-00 Velomitor CT Velocity Transducer and can advise on compatible cables and accessories. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
