Bently Nevada 190501-00-00-04 Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime, the Bently Nevada 190501-00-00-04 Velomitor CT Velocity Transducer delivers reliable measurement. This sensor converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. Designed for harsh industrial environments, it combines precision with durability.

Technical Specifications Breakdown

The 190501-00-00-04 offers a sensitivity of 3.94 mV/mm/s ±5%, ensuring accurate readings across a wide frequency range. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, extending to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. The output bias voltage sits at 10.1 Vdc ± 1.0 Vdc, with a dynamic output impedance under 400 Ω typical. Amplitude linearity holds within ±2% up to 63.5 mm/s pk. These parameters make it ideal for critical rotating machinery monitoring.

Industry Applications

In petrochemical plants, the 190501-00-00-04 monitors pumps and compressors, detecting early vibration changes that signal impending failure. Power generation facilities use it on turbines and generators to prevent unplanned outages. Its intrinsically safe certifications—Ex ia IIC T4 and AEx ia IIC T4—allow installation in hazardous areas like Class I, Division 1 environments. This transducer reduces downtime by providing actionable data for predictive maintenance programs.

Installation & Setup Guidance

Mount the 190501-00-00-04 on a clean, flat surface with a 33 mm diameter area. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) for secure attachment. The 2-pin MIL-C-5015 connector simplifies wiring: Pin A goes positive relative to Pin B when velocity moves from base to top. Use cable part number 02173006 up to 305 metres (1,000 ft.) without signal degradation. Any orientation works, offering flexibility in tight spaces.

Maintenance & Reliability

Built with 316L stainless steel case and connector, the 190501-00-00-04 withstands corrosive environments. Its internal electronics are isolated from the case, reducing ground loop issues. Operating temperature ranges from -40°C to +85°C, with storage up to +100°C. The shock limit of 5000 g pk ensures survival during accidental impacts. Regular inspection of cable integrity and connector cleanliness maintains optimal performance. This robust design minimizes lifecycle costs by extending service intervals.

Selection Guide & Purchasing Advice

When ordering the 190501-00-00-04, verify the agency approval option (04 includes CSA/NRTL/C, ATEX/IECEx/CSA for Class I, Division 1 and Zone 0/1). Confirm mounting hardware: option 00 means no stud.
