Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-02-00-00 Velomitor CT Velocity Transducer delivers precise, reliable measurements. This industrial-grade sensor converts mechanical velocity into an electrical signal for continuous monitoring and protection. Designed for harsh environments, it provides consistent performance across a wide temperature range.
Technical Specifications Breakdown
The 190501-02-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration detection. 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 is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. Dynamic output impedance is less than 400 Ω typical. These specs make it suitable for monitoring rotating equipment like pumps, fans, and compressors.
Industry Applications
In petrochemical plants, the 190501-02-00-00 monitors critical pumps and compressors, detecting early signs of bearing wear or imbalance. Its operating temperature range of -40°C to +85°C (-40°F to +185°F) and 100% condensing humidity tolerance allow deployment in outdoor or washdown areas. The 316L stainless steel case resists corrosion, ideal for offshore platforms and chemical processing.
Installation & Setup Guidance
Mount the transducer using the included 3/8-in 24 to 1/2-in 20 stud with a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The mounting surface must be clean and flat, with a diameter of 33 mm (1.3 in). Connect via the MIL-C-5015 2-pin connector. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation. Ensure Pin A connects to the positive signal input; polarity is defined as Pin A going positive with respect to Pin B when velocity is from base to top.
Maintenance & Reliability
This transducer requires minimal maintenance due to its sealed 316L stainless steel construction and internal electronics isolated from the case. The shock limit of 5000 g pk ensures survival in high-impact environments. Periodic inspection of the cable and connector for damage is recommended. Verify output bias voltage periodically to confirm proper operation. The absence of moving parts enhances long-term reliability.
Selection Guide & Purchasing Advice
Before ordering the 190501-02-00-00, confirm your application requires a velocity transducer with a sensitivity of 3.94 mV/mm/s and a frequency response starting at 3.0 Hz. Verify the mounting thread size (3/8-in 24 to 1/2-in 20) and connector type (MIL-C-5015). For intrinsically safe installations, refer to agency approval options 01 through 04. SpareTechPLC stocks this model and can assist with compatibility checks. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
